The Indian Hemp Drugs Commission Report, completed in 1894, was an Indo-British study of cannabis usage in British India.
[1] By 2 March 1893, the House of Commons of the United Kingdom was concerned with the effects of hemp drugs in the province of Bengal, India.
The report the commission produced was at least 3,281 pages long, with testimony from almost 1,200 "doctors, coolies, yogis, fakirs, heads of lunatic asylums, bhang peasants, tax gatherers, smugglers, army officers, hemp dealers, ganja palace operators and the clergy.
"[2] A sociological analysis of the report reveals that the commission's visits to asylums all over India helped to undermine the then prevailing belief that consumption of ganja causes insanity.
There are also many cases where in tracts with a specially malarious climate, or in circumstances of hard work and exposure, the people attribute beneficial effects to the habitual moderate use of these drugs; and there is evidence to show that the popular impression may have some basis in fact.
Speaking generally, the Commission are of opinion that the moderate use of hemp drugs appears to cause no appreciable physical injury of any kind.
The large number of witnesses of all classes who professed never to have seen these effects, the vague statements made by many who professed to have observed them, the very few witnesses who could so recall a case as to give any definite account of it, and the manner in which a large proportion of these cases broke down on the first attempt to examine them, are facts which combine to show most clearly how little injury society has hitherto sustained from hemp drugs (1:264).
