1. A 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.
5. A 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, ÒJudged by this test, there is room even in Bengal for increased taxation" (ibid., p. 311).

Conceivably, alcohol may be a greater risk 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.).
