Abstract:

Marijuana legalization offers an important advantage over 
decriminalization in that it allows for legal distribution and taxation of 
cannabis.   In the absence of taxation, the free market price of legal 
marijuana would be extremely low, on the order of five to ten cents 
per joint.  In terms of intoxicating potential, a joint is equivalent to at 
least $1 or $2 worth of alcohol, the price at which cannabis is currently 
sold in the Netherlands.  The easiest way to hold the price at this level 
under legalization would be by an excise tax on commercial sales.  An 
examination of the external costs imposed by cannabis users on the 
rest of society suggests that a "harmfulness tax" of $.50 -$1 per joint is 
appropriate.  It can be estimated that excise taxes in this range would 
raise between $2.2 and $6.4 billion per year.   Altogether, legalization 
would save the taxpayers around $8 - $16 billion, not counting the 
economic benefits of hemp agriculture and other spinoff industries.

The Case for Legalization:

    As drug war hysteria subsides it becomes increasingly certain that 
there must be a serious re-examination of the laws prohibiting 
marijuana.  The decriminalization of soft drugs has now emerged as an 
active political issue in Germany,  Italy, Switzerland, France and 
Australia. The policies being considered range from "decriminalization," 
or repeal of criminal penalties for private use and cultivation of 
cannabis, to full "legalization," in which cannabis is commercially sold 
like alcohol, tobacco and other commodities.
    Decriminalization has enjoyed impressive support from a 
succession of official panels, including the Presidential Commission on 
Marijuana, the California Research Advisory Panel, and the Canadian Le 
Dain Commission.  Decriminalization was also officially  the policy of the 
state of Alaska from 1976 through 1990, when it was narrowly 
overturned in a referendum.  The basic appeal of decriminalization is 
to reduce the harm of criminal punishment and respect personal 
freedom and privacy, while avoiding offensive commercialization.  The 
basic flaw in decriminalization is that it does not make allowance for 
pot users who cannot or will not grow their own.   The result is to 
create an illicit black market for cannabis that is neither regulated nor 
taxed, leaving many of the same basic enforcement problems as 
prohibition.
    These problems can be avoided by legalization, under which 
cannabis could be legally sold, taxed and regulated like alcohol or 
tobacco.   (It should be noted that legalization need not involve the 
evils of commercialization, given suitable restrictions on advertising).  
The world presently has no example of a completely legalized cannabis 
market, since this is forbidden by the Single Convention Treaty on 
Narcotics.   The nearest approximation may be seen in the Netherlands, 
which officially tolerates the possession and sale of up to 30 grams of 
hashish or marijuana in coffeehouses, although distribution and 
manufacture are technically illegal and large-scale traffickers are 
punished.  The apparent success of the Dutch in controlling hard drug 
abuse without a major hashish abuse epidemic has led a league of 15 
European cities to endorse the principle of legalized cannabis in the so-
called Frankfurt Resolution.  An important advantage of legalization is 
to open the door to taxation of marijuana - a potentially valuable 
source of public revenue - while eliminating the need for an illegal 
market.
    In the following, we will examine more closely the economics of a 
legalized cannabis market.

The Cheapest Intoxicant:

    In an  untaxed free market, cannabis ought to be as cheap as other 
leaf crops.  Bulk marijuana might reasonably retail at the price of other 
medicinal herbs, around $.75 -$1.50 an ounce.  Premium cured and 
manicured sinsemilla buds might be compared to fine teas, which 
range up to $2 per ounce,  or to pipe tobacco, which retails for $1.25-
$2.00.  This appears to have been the historical price range for 
cannabis in the days when it was still legal:  advertisements from 
medical catalogs imply that it sold for around $2.50-$5 per pound  in 
1929-30.  1    Adjusting for inflation, this works out to $1.20-$2.40 per 
ounce,  a breathtaking 100- to 300-fold reduction from today's illicit 
prices, which range from $100- $200 per ounce for low-grade Mexican 
to $400- $600 per ounce for high-grade sinsemilla.
    It is useful to translate these prices to a per-joint basis, where one 
joint is defined to represent the standard dosage of marijuana.   The 
number of joints in an ounce depends on the potency of the product 
involved, where potency is measured in terms of the concentration of  
tetrahydrocannabinol (THC), the chief psychoactive ingredient in 
marijuana.  THC potencies typically range from 2-3%  for low-grade 
leaf to 10-15% or more for premium sinsemilla buds.  We will define a 
standard dose of THC to be that contained in the government's own 
marijuana joints, which NIDA supplies to researchers and selected 
human subjects.  These consist of low-quality  2.5%-3% potency leaf 
rolled into cigarette-sized joints of 0.9 grams, yielding a 25 milligram 
dose of THC.   The same dose can be had in a slender one-third or one-
quarter gram joint of 10-12% sinsemilla.    A typical joint has been 
estimated to weigh about  0.4 grams.2  Taking this as a standard, we 
will define a "standard joint" to be 0.4 grams of average-quality 6% 
buds.   Thus an ounce of "standard pot" equals 60 joints,  an ounce of 
12% sinsemilla  120, and an ounce of government pot only 30 joints.   
Due to the fact that the price of marijuana tends to be proportional to 
potency, the price of a one-quarter gram joint of $600-per-ounce 
sinsemilla is about the same as a one-gram joint of $150-per-ounce 
ditchweed, that is around $6.   
    We have seen that in the absence of taxation, the price of legal 
marijuana would be cut by a factor of 100 or more.  At this rate, a joint 
costing $6 today would cost less than $.06 in a free legal market.  It 
therefore appears that marijuana would be a very cheap bargain 
compared to other intoxicants, including alcohol. 
    The free-market price of joints can also be calculated by comparison 
to tobacco cigarettes, which would probably cost the same to 
manufacture.  Cigarettes now sell at an average of $1.83 per pack, or 
$.09 per cigarette, one-quarter of which represents federal and state 
taxes.3  There is no reason to think that joints could not be sold for the 
same price under legalization.  
    At a nickel per joint, marijuana would be a uniquely economical 
intoxicant.  For only one-half dollar per day, a pothead could nurse a 
whopping ten-joint per day habit.   It may be doubted whether public 
opinion would tolerate so low a price for marijuana.   On one hand, it 
would invite extensive abuse.  Parents would no doubt object against 
making a serious marijuana habit so affordable for their young.  
Moreover, cheap pot would also pose a serious challenge to the alcohol 
industry, a powerful political interest, whose products are over ten 
times as expensive.  In order to make legalization politically palatable, 
it would almost certainly be necessary to raise the price through 
taxation or regulation.

Putting a Value on Cannabis:

    One way to estimate a reasonable price for marijuana is to evaluate 
it in comparison to the major competing intoxicant, alcohol.   While it is 
impossible to make an exact comparison between pot and booze, since 
their duration and effects are different and dosages vary from person 
to person, a joint might be roughly equated to an intoxicating dose of 
alcohol - between one and two ounces, or two to four drinks.   Thus one 
joint might be worth two to four 12-oz. beers or  1/3 - 2/3 bottle of 
wine.  These are currently sold on grocery shelves at a minimum price 
of around $1.25 - $2.50.   It may therefore be concluded that a 
reasonable minimum price for marijuana should be around $1.25 - 
$2.50 a joint, with higher prices for premium grades.  This works out to 
$75 - $150 per ounce for standard 6%-potency marijuana.
    Coincidentally, this price range is in line with that presently seen in 
the Netherlands, where coffeehouses sell hashish and sinsemilla by the 
gram for 4 to 15 guilders, or $2.15- $8.10.4  Taking the cheaper grade 
to yield two joints per gram and the premium grade four, this works 
out to $1 to $2 per joint.   The fact that the Dutch have not been 
plagued by widespread cannabis abuse and indeed believe they have 
obtained public health benefits from their system provides reassurance 
that this price level is realistic.5 
     It should be noted that Dutch prices are inflated by the fact that 
cannabis remains illegal, not by any form of legal taxation  (though the 
state does tax cannabis indirectly through the sales tax on cafes).  
Although Dutch authorities tolerate a number of small-scale domestic 
producers, international traffickers and domestic distributors are both 
subject to busts at the whim of the police.  As a result, Dutch 
consumers pay inflated black market prices.  This is not necessarily the 
optimal model for marijuana price control, since the lion's share of the 
profits go to illicit traffickers.
    In a legalized market, the easiest way to maintain marijuana prices 
would appear to be through some form of excise tax, as presently 
imposed on alcohol and tobacco.  This could conveniently be assessed 
on licensed manufacturers or wholesalers, like the federal tax on 
cigarettes.  Aside from a strict prohibition against sales to unlicensed 
distributors, cultivators need not be directly regulated.   Excise taxes 
have the advantage of being easy to enforce, since they involve a 
relatively small number of distributors.  The latter in turn pass the tax 
along with a markup, magnifying the price increase throughout the 
distribution chain.  
    Another way to control the market would be to tax or regulate 
cultivation.  However, experience shows that it is no easy task to track 
down and regulate marijuana growers.  More so than alcohol or 
tobacco, marijuana lends itself easily to small-scale home cultivation 
and production.   The problem therefore arises as to how to treat home 
cultivation in the legal market.  Clearly, the sale of untaxed home 
marijuana must be banned.  In theory, home cultivation could also be 
taxed and licensed in order to maintain high prices.  However, it seems 
unlikely that such requirements could be enforced in a world of 
legalized marijuana. The policing of home growers would appear to 
require many of the most odious and objectionable techniques of 
current marijuana enforcement, such as  helicopter surveillance, 
snooping on homes and spying on garden stores. 
    The most practical policy is thus likely to be the one most consistent 
with principles of personal freedom and civil liberties, namely to let 
Americans grow their own cannabis at home, just as they might  grow 
tomatoes, apples or grapes.  The inducements to home cultivation 
should not be exaggerated:  in Alaska, where it was the one legal way 
to get marijuana before 1991, pot continued to be sold illicitly at prices 
around $250 an ounce, proof that many pot smokers are quite 
disinclined to grow on their own.   Nonetheless, home cultivation would 
effectively put a lid on the amount marijuana could be taxed, since 
consumers would be induced to grow their own if prices rose too high. 
    Another possible way to limit marijuana abuse would be to regulate 
consumers directly, for instance, by requiring "user's licenses" for the 
right to buy or use marijuana, as proposed by Kleiman.6  By charging 
fees for these licenses, the state could raise tax revenues.   User fees 
are apt to be more costly to administer than excise taxes, since they 
must be collected from a much wider population.   More importantly, 
they are also apt to be unenforceable, given the ease with which 
unlicensed users can grow their own at home.  One situation in which 
user fees might be attractive would be under a regime of 
decriminalization,  where commercial sales were illegal.   Consumers 
might then be allowed to purchase a license to consume and grow 
marijuana for personal use.  In this system, licenses would afford the 
one opportunity for the government to derive tax revenues from 
marijuana, while an active marijuana surveillance program  would still 
be needed to prevent commercial sales and unlicensed use. 
    The problem of cannabis enforcement was first rigorously addressed 
one hundred years ago by the British Indian Hemp Drugs Commission.7  
The commission concluded that cannabis prohibition was not 
practicable, and that the best solution was to tax it to the extent 
possible.  After examining the different regulatory systems in various 
provinces of India, the Commission especially recommended the 
system in Bengal, where cannabis was taxed more rigorously than in 
other provinces by means of a system of excise fees and vendors' 
licenses.   Noting that hemp drugs tended to be much cheaper than 
liquor, the Commission argued that cannabis was undertaxed.8   It also 
noted that there were regions where cannabis grew wild, in which it 
was virtually impossible to control traffic in bhang, a low-potency 
beverage made from leaves.  Cannabis remained legal in India  until 
recent years, when it was banned under pressure from the U.S.

Computing A Harmfulness Tax

    The question might well be asked from a libertarian free-market 
perspective why cannabis (or other drugs) should be taxed in the first 
place.  Why should government concern itself with regulating what is 
in essence a private decision, that is, what kind of drugs to ingest?  
Why shouldn't prices simply be settled by supply and demand?  
    The best answer is that marijuana consumption may impose costs on 
innocent third parties who do not consume it.  According to standard 
economic theory, such "external costs" may be compensated by means 
of a harmfulness tax. 9 Examples of external costs of drug abuse 
include increased insurance costs, accidents affecting third parties, and 
drug-induced violence and criminality.  In principle these costs must 
be distinguished from "internal costs" that fall on the user, such as ill-
health, reduced personal income, poor achievement, etc.  Because users 
already pay for the latter, there is no sense in making them pay again 
through a tax.  
    From a non-libertarian, public health perspective, higher taxes are 
often justified simply as a disincentive to prevent people from 
overindulging in what is presumably an unhealthy habit.  This 
argument is most persuasive in the case of highly addictive drugs such 
as nicotine, where naive users run a high risk of getting themselves 
trapped in an unhealthy habit due to initial misjudgment.  Punitive 
taxation appears less justifiable in the case of cannabis, not only 
because it has low addictivity, but also because of the ease with which 
home growers can evade excessive taxes.   
     In the  following discussion, we will examine the external costs of 
marijuana abuse as the basis for a prospective harmfulness tax.  At the 
outset, it should be noted that much further epidemiological research is 
needed to accurately assess the costs of marijuana;  nonetheless,  it is 
possible to hazard a guess at their magnitude.  Overall, the general 
scientific consensus is that marijuana has definite deleterious effects, 
though less so than alcohol or tobacco.  In the words of the California 
Research Advisory Panel: "An objective consideration of marijuana 
shows that it is responsible for less damage to society and the 
individual than are alcohol and cigarettes."10  
     From a physiological standpoint, the major health risk of heavy 
marijuana use appears to be respiratory harm due to smoking.11   A 
recent epidemiological study by the Kaiser Permanente Center for 
Health Research found that daily cannabis smokers had a 19% higher 
rate of respiratory complaints.12    Aside from cases of passive 
smoking, these must be counted as internal costs, except to the extent 
that they may raise group health insurance costs for others.   (There 
are actually good grounds to believe that legalization would reduce the 
costs of respiratory damage from marijuana smoking by encouraging 
the development of better smoke filtration technology, the substitution 
of more potent, less smoke-producing varieties of marijuana, and the 
substitution of oral preparations for smoked marijuana.)
    More important than the respiratory harm of marijuana is the 
increased risk of accidents due to mental impairment.   In the Kaiser 
study, this emerged as the number one hazard of marijuana use, with 
daily users reporting a  30% higher rate of injuries than non-users. 
Presumably, these injuries reflected an increased risk of accidents that 
might also involve third parties.  Hence, accidents should probably be 
counted as the major external cost of marijuana use.   Other concerns, 
such as amotivation, poor school performance and the controversial 
"gateway drug" syndrome are more properly classified as internal 
costs. 
    In order to quantify the external costs of marijuana, it is useful to 
consider those of alcohol and tobacco.  These are shown in Table 1, 
based on an analysis by W. Manning et al.13  aimed at estimating the 
appropriate level of taxation for alcohol and cigarettes.   Manning's 
analysis shows how the health costs imposed on the insurance system 
by tobacco- and alcohol-related illness tend to be counterbalanced by 
the fact that smokers and drinkers  die younger, and therefore collect 
fewer pension and retirement benefits.

Pay Their Way?," JAMA 261:1604-9.

    In the case of tobacco, Manning estimates the gross cost of medical 
care for smoking-related diseases at $.26 a pack, or just over one 
penny per cigarette.   This turns out to be largely compensated by 
savings in retirement pensions and nursing home care for smokers.  
The final balance is highly sensitive to technical assumptions about the 
economic discount rate, and can even be made to show net external 
benefits at  interest rates under 3%.  Manning's final net estimate of 
$.15 per pack assumes a 5% interest rate.  
    By estimating the equivalency between joints and cigarettes, one can 
translate these costs to marijuana.   On a weight-for-weight basis, pot 
smokers inhale about four times as much noxious tars as cigarette 
smokers;14 as we have seen, however, the average joint weighs about 
half as much as a cigarette.  Also, cannabis lacks nicotine,  a leading 
factor in tobacco-related heart disease.  It seems reasonable on this 
basis to suppose that a joint is equal to less than two cigarettes, putting 
the net external cost of marijuana smoking at under 1.5 cents per joint.      
    One fault in Manning's accounting of external costs is that it excludes 
the costs of second-hand smoking,  which he estimates at $.23 per 
pack, on the questionable grounds that these costs are mainly internal 
to the users' families.  We treat them here as external costs instead.  
There are grounds to think that passive smoking is of much less 
concern with cannabis since pot smokers emit less smoke than 
cigarette smokers.  It therefore seems reasonable to conclude that the 
total smoking-related costs of active and passive pot smoking are 
unlikely to exceed two cents per joint.
     Turning to alcohol,  Manning concludes that the net medical-less-
pension costs of alcoholism-related disease are $.26 for every "excess 
ounce" of alcohol, which is defined to mean an ounce in excess of one 
per day (Manning does not try to account for the possibility that 
moderate consumption may actually extend life).  These costs turn out 
to be greatly outweighed by the cost of alcohol-related accidents, which 
he estimates at $.93 per excess ounce.  This figure includes traffic 
accidents to third parties caused by drunken drivers, but does not 
appear to include other alcohol-related accidents.  Also missing from 
Manning's account are the external costs of alcohol-related violence.   
Altogether, Manning concludes that the total cost of alcohol is $1.19 per 
excess ounce, or $.48 per ounce when averaged over all alcohol drunk.   
     While the cost of alcohol seems clearly dominated by accidents, it is 
unclear how to relate these to marijuana.  The burden of expert opinion 
appears  to be that marijuana is less of an accident risk than alcohol, 
though this is disputed.15    Studies of fatal car accidents indicate that, 
at least on the road, marijuana tends to be a secondary risk factor 
compared to alcohol.16  On the other hand, one survey of  trauma 
patients found that with respect to all accidental injuries, cannabis may 
be every bit as much a risk factor as alcohol.17  In terms of 
intoxicating potential, one joint probably lies between one ounce and 
one excess ounce of alcohol.   At the high end, if one equates a joint 
with one excess ounce, the accident costs of pot would be $.93 per joint.  
More reasonably, one could equate a joint with an "average" ounce of 
alcohol, the accident costs of which work out to $.38.  There are reasons 
to favor a lower external cost on marijuana relative to alcohol, notably 
the fact that marijuana tends to suppress violence, whereas alcohol 
tends to aggravate it.   From this perspective alone, an overall shift 
from alcohol to marijuana may be desirable.
    In conclusion, one can reasonably argue that marijuana should be 
assessed a harmfulness tax of  $.40 to $.95 per joint - or, say, $.50 - $1 
in round figures.  Experience indicates these taxes would probably be 
magnified at least twofold in the market, resulting in a minimum retail 
price of $1 - $2 per joint.18   Happily, this is consistent with the target 
price range we derived previously.  
    Different lines of reasoning thus converge to argue that cannabis 
should be taxed at  $.50 to $1 per joint.  That is $15-$30 per ounce for 
low-grade 3% leaf or $30 - $60 per ounce for 6% standard cannabis.  
Ideally, the tax rate per ounce should be proportional to THC potency.  
In practice, this could be implemented through a schedule of fixed 
product categories similar to those used for alcohol (beer, wine and 
hard liquor).   These categories might include: (1) leaf (potency <3%), 
(2) standard blend cannabis (4 - 10% potency), and (3) high-grade 
sinsemilla or hashish (potency>10%).  Other cannabis-based products, 
such as hashish, hash oil, tonics and foodstuffs, could be taxed 
according to their leaf or bud content.  It should be noted that low-
grade leaf, though harsh for smoking, could play a valuable role in the 
market as a source for cooked preparations and extracts, which are 
likely to play an increasing role in the market as health-conscious 
consumers seek to avoid smoking.

Revenues From Legalization:

    Assuming a tax of  $.50 or $1 per joint, we can venture a rough 
estimate of the revenues that could be raised from legalized cannabis.  
According to the 1991 National Household Survey on Drug Abuse, some 
19.5 million Americans used marijuana at least once in the year, of 
whom 5.3 million used at least once a week and 3.1 million daily.  
About one-half  of the latter are thought to be multipleJdaily users, 
who can be expected to make up the bulk of total consumption.19     
Assuming the mean consumption of all daily users is two or three 
joints per day, current national consumption can be figured to exceed 7 
to 10 million joints per day, or 1200 to 1800 metric tons of 6% THC 
cannabis per year.  These figures may well be low, since the Household 
Survey underestimates actual use.  A considerably higher estimate is 
given by Kleiman, who puts 1986 consumption at the equivalent of 
2700 metric tons of 6% THC cannabis;  other trafficking-based 
estimates range as high as 4700 tons.20
    Consumption would surely expand further in a legal market where 
joints were freely and cheaply available.  At the height of marijuana's 
popularity around 1979, consumption was over twice that of today.  
One factor that could significantly expand the demand for legal 
cannabis in the future would be the development of mild cannabis 
beverages like bhang, which traditionally constituted the bulk of 
demand in India.  It is therefore not unreasonable to forecast ultimate 
consumption at 15 - 30 million joints per day, or 2750 - 5500 metric 
tons of 6% THC cannabis per year.  
    The obvious question remains what portion of consumption would 
be absorbed by home growers.   As we have seen, it is probably 
hopeless to limit personal use cultivation.   Home growing would 
naturally be most attractive to heavy users with little money, who 
probably account for a major share of consumption. At $2 per joint, a 
three-joint per day habit would cost over $2000 a year, a hefty 
incentive for any home gardener.   It therefore seems likely that home 
cultivation would absorb a substantial portion of  the consumption of 
multiple daily users, who are estimated to account for 60% of the total 
market.21
    We shall estimate the size of the commercial cannabis market by 
posing two price scenarios.  (1) Given a $.50 excise tax and a minimum 
price of $1 per joint, we will assume that home growing absorbs 20% of 
consumption (that is, one-third of the consumption of multiple daily 
smokers), leaving a commercial demand of 12-24 million joints per 
day.  This works out to about $2.2 to $4.4 billion per year in tax 
revenues.  (2) Given a $1 excise tax and a price over $2 per joint, we 
assume commercial consumption would be cut by 40% to 9 - 18 million 
joints, yielding $3.2 to $6.4 billion per year.  We conclude that 
revenues from cannabis excise taxes might range from $2.2 to $6.4 
billion per year.    This is comparable to the revenues currently raised 
through the federal tax on alcohol ($8 billion) and cigarettes ($5 
billion).  
    By comparison, in the Netherlands, a nation of 15 million people, 
total domestic sales of soft drugs have been estimated at under 1 
billion guilder, or $500 million. 22 Extrapolating this to the U.S. 
population, one arrives at total retail sales of about $8 billion.  If one-
half of this went to taxes, one would get $4  billion per year.   
    Similarly, in Bengal, with a population of 50 million, the Indian 
Hemp Drugs Commission reported total tax revenues from ganja of 24 
million rupees in the year 1892-3, or about $10 million (1892 
dollars).23    Extrapolated fivefold to the current U.S. population, this 
would work out to $700 million in 1992 currency.  The tax on ganja 
was about 8 rupees per kilo in Bengal, or just $.04 per joint in current 
dollars. 24 Were the tax increased tenfold to the level we have 
proposed, revenues would presumably increase to $7 billion, minus a 
substantial amount due to decreased demand from higher prices.
    In addition to excise taxes, states could impose sales taxes on 
cannabis.  Unlike excise taxes, sales taxes would be proportional to final 
retail price, including the added markup for premium brands.  Just like 
alcohol, it can be expected that marijuana would often be sold for 
substantially more  than its minimum price:  in a hotel bar, a good 
sinsemilla joint might well go for $5.   Assuming average retail prices 
of $ 1.50 - $2.50  per joint, and sales taxes between 4% and 6%, the 
total revenues raised might range from $200 million to $1.3 billion.
    In addition, legalization would create numerous revenue-generating 
spinoff industries, such as coffee houses, gardening equipment and 
paraphernalia.  The city of Amsterdam, with a million people, boasts 
300 coffee houses retailing cannabis.25    Translated to the U.S, this 
would amount to over 60,000 retailers and 100,000 jobs.
     Finally, the legalization of cannabis would also permit the 
agriculture of hemp, a versatile source of fiber, protein, biomass and 
oil, which was once one of America's top crops.  Hemp production might 
well rival that of other leading crops such as cotton or soy beans, which 
are currently on the order of $ 6 - 10 billion per year.
    On the other side of the ledger, legalization would save the 
considerable economic and social costs of the current criminal 
prohibition system.  Current federal drug enforcement programs run at 
$13 billion per year.  State and local programs are probably of similar 
or greater magnitude:  in California, the Legislative Analyst's Office 
estimated the cost of state drug enforcement programs at around $640 
million per year in 1989-90, plus perhaps twice as much more in local 
expenditures.26   A sizable chunk of these costs involve cannabis, 
which accounts for 30% of drug arrests nationwide.   Legalization of 
cannabis would also divert demand from other drugs, resulting in 
further savings.  If legalization reduced current narcotics enforcement 
costs by one-third to one-fourth, it might save $6 - $9  billion per year.
    The economic benefits of marijuana legalization are summarized in 
Table 2.  The total direct savings to government in taxes and 
enforcement come to some $8 - $16 billion per year.  These figures are 
somewhat lower than those sometimes bandied about in public 
discourse, as both legalizers and prohibitionists have a tendency to 
make consumption estimates that are in our opinion inflated.  
Nonetheless, the benefits of legalization seem both substantial and 
undeniable, and deserve to be taken seriously.

1A 1929-30 Parke-Davis catalog advertised a 4 oz. bottle of 
tincture of cannabis of 20% potency for $5,  which works out to 
the equivalent of  $5 per pound at 5% potency.   Another Squibb 
catalog of uncertain date lists powdered cannabis at $2.50/lb: 
from the collection of Dr. Tod Mikuriya.

5A similar price range may be found in the state of South 
Australia, where the cultivation of fewer than 10 plants has 
been decriminalized to a minor misdemeanor punishable by a 
fine.  There cannabis is sold on the black market for about $100-
$150 per ounce, about one-half to one-third the price elsewhere 
in Australia.

8 In Bombay, the Commission heard testimony that "the 
ordinary liquor consumer pays twice as much for what he wants 
as the ordinary ganja consumer would, or three times as much as 
the ordinary bhang drinker.  I think the rates should be 
equalized." (Report of the British Indian Hemp Drugs 
Commission, 1893-4,, Vol. 1, Chap. XVI, p. 327).   Even in Bengal, 
where taxes were  higher, the Commission found that "the 
average allowance of liquor to the habitual consumer was "much 
higher than in the case of ganja."  It concluded, "Judged by this 
test, there is room even in Bengal for increased taxation"  (ibid., 
p. 311).

factor in traffic accidents because it promotes speeding, whereas 
pot smoking-drivers tend to slow down.  On the other hand, 
marijuana may be more involved in other kinds of accidents 
where forgetfulness or loss of concentration are a risk factor. 
18 In Bengal in 1892-3, excise taxes and licensing fees on ganja 
totaled more than 10 rupees per ser (i.e., kilo), over one-half the 
average retail price of 20 rupees.   This appears to have 
represented a 10-fold increase over the free-market price of 
cannabis, which sold for as little as 2 rupees in other provinces 
where it was lightly taxed.  Report of the British Indian Hemp 
Drugs Commission, Vol. 1, Ch. XV p.295  and Ch. XVI pp. 311-2, 
p.321.  The U.S. cigarette tax has historically  accounted for about 
25%-50% of retail prices, according to the Tobacco Institute (op. 
cit.).
