Panama Canal Zone Report, 1925. “There is no evidence… that any deleterious influence on the individual using [cannabis]”.

Siler Commission, Panama Canal Zone Report, 1930. Reported that cannabis use was harmless, and, having subjected to medico-scientific clinical monitoring, heavy cannabis smoking produced no effect upon motivation or performance.

LaGuardia Commission Report, 1944. “Cannabis smoking does not lead directly to mental or physical deterioration… Those who have consumed marijuana for a period of years showed no mental or physical deterioration which may be attributed to the drug”.

The Wootton Report, 1969. “The long term consumption of cannabis in moderate doses has no harmful effect”.

Marijuana: A Signal of Misunderstanding: The Shafer Report, 1972. US National Commission on Marijuana and Drug Abuse. Recommended that the WHO should do a reassessment of cannabis.

NIMH Jamaican Study, 1972. “No impairment of physiological, sensory and perceptual performance, concept formation, abstracting ability and cognitive style and tests of memory”.

Some participants had smoked at least two to four large cigarettes (each containing 1/4 to 1/2 ounce of cannabis) over 16 hours a day for periods of up to 50 years. ‘the most impressive thing … is the true paucity of neurological abnormalities’. Heavy cannabis consumers suffered no apparent psychological or physical harm. (‘Hemp, Lifeline to the Future’, C Conrad, 1994).

Costa Rican Study, 1982. “Users in our matched-pair sample smoked marihuana in addition to as many tobacco cigarettes as did their matched non-using pairs. Yet their small airways were, if anything, a bit healthier than their matches. We must tentatively conclude either that marihuana has no harmful effect on such passages or that it actually offers some slight protection against the harmful effects of tobacco smoke”. Found that there was no distinguishable harm that could be attributed to cannabis usage.

DEA Administrative Law Judge, FL Young, 1988. “Nearly all medicines have toxic, potentially lethal effects. But marijuana is not such a substance. There is no record in the extensive medical literature describing a proven, documented cannabis-induced fatality. Simply stated, researchers have been unable to give animals enough marijuana to induce death. In practical terms, marijuana cannot induce a lethal response as a result of drug-related toxicity. In strict medical terms marijuana is far safer than many foods we commonly consume. Marijuana, in its natural form, is one of the safest therapeutically active substances known to man”.

The Lancet, Volume 346, Number 8985, November 11, 1995 (Editorial). “The smoking of cannabis, even long term, is not harmful to health. Leaving politics aside, where is the harm in decriminalising cannabis? There is none to the health of consumers. Sooner or later politicians will have to stop running scared and address the evidence: cannabis per se is not a hazard to society but driving it further underground may well be”.

‘Marihuana Reconsidered’, Prof. L Grinspoon, 1996. “…as in the case of psychiatric illness, no level of use has yet been discovered that qualifies as obviously so immoderate that it causes physical disease”.

British Medical Association, Therapeutic Uses of Cannabis, 1997. “Individual cannabinoids have a therapeutic potential in several conditions in which other treatments are not fully adequate. Cannabioids and cannabis should be legalised for wider medical use under medical supervision. The report found that there was “good evidence” that several cannabinoids had analgesic and anti-inflammatory properties.

House of Lords Report, 1998. The Lords Science and Technology Committee urges a “change in the law to allow derivatives of the drug to be used legally”.
