Cannabis improves night vision: a case study of dark adaptometry and scotopic sensitivity in kif smokers of the Rif mountains of northern Morocco | cannabisabstracts.info. This is something I have always suspected. I would not be surprised if similar effects can be found for sound, taste and scent. Previous reports have documented an improvement in night vision among Jamaican fishermen after ingestion of a crude tincture of herbal cannabis, while two members of this group noted that Moroccan fishermen and mountain dwellers observe an analogous improvement after smoking kif , sifted Cannabis sativa mixed with tobacco ( Nicotiana rustica ).
Field-testing of night vision has become possible with a portable device, the LKC Technologies Scotopic Sensitivity Tester-1 (SST-1). This study examines the results of double-blinded graduated THC administration 0–20 mg (as Marinol ® ) versus placebo in one subject on measures of dark adaptometry and scotopic sensitivity. E.

Cannabis and Driving Studies: Scientific Evidence. Marijuana and Driving: A Review of the Latest Scientific Evidence It is well-established that alcohol increases accident risk.
Evidence of marijuana's culpability in on-road driving accidents is much less convincing. Although cannabis intoxication has been shown to mildly impair psychomotor skills, this impairment does not appear to be severe or long lasting. In driving simulator tests, Cannabis impairment is typically manifested by subjects decreasing their driving speed and requiring greater time to respond to emergency situations. Nevertheless, this impairment does not appear to play a significant role in on-road traffic accidents. A 2002 review of seven separate studies involving 7,934 drivers reported, "Crash culpability studies have failed to demonstrate that drivers with cannabinoids in the blood are significantly more likely than drug-free drivers to be culpable in road crashes.
" Crash culpability studies On-Road Performance Studies Driving simulator studies REFERENCE: G. Study says marijuana no gateway drug | Science Blog. Marijuana is not a “gateway” drug that predicts or eventually leads to substance abuse, suggests a 12-year University of Pittsburgh study. Moreover, the study’s findings call into question the long-held belief that has shaped prevention efforts and governmental policy for six decades and caused many a parent to panic upon discovering a bag of pot in their child’s bedroom.
The Pitt researchers tracked 214 boys beginning at ages 10-12, all of whom eventually used either legal or illegal drugs. When the boys reached age 22, they were categorized into three groups: those who used only alcohol or tobacco, those who started with alcohol and tobacco and then used marijuana (gateway sequence) and those who used marijuana prior to alcohol or tobacco (reverse sequence). “The gateway progression may be the most common pattern, but it’s certainly not the only order of drug use,” said Ralph E. Although this research has significant implications for drug abuse prevention approaches, Dr. Medical cannabis. Cannabis indica fluid extract, American Druggists Syndicate, pre-1937. Cannabis has been used to reduce nausea and vomiting in chemotherapy and people with AIDS, and to treat pain and muscle spasticity;[2] its use for other medical applications has been studied, but there is insufficient data for conclusions about safety and efficacy.
Short-term use increases minor adverse effects, but does not appear to increase major adverse effects.[3] Long-term effects of cannabis are not clear,[3] and there are safety concerns including memory and cognition problems, risk for dependence and the risk of children taking it by accident.[2] Medical cannabis can be administered using a variety of methods, including vaporizing or smoking dried buds, eating extracts, and taking capsules. Medical uses Cannabis as illustrated in Köhler's book of medicinal plants from 1897 Nausea and vomiting Pain Multiple sclerosis Studies of the efficacy of cannabis in treating multiple sclerosis have produced varying results.

Erowid: Health Effects. Five Things You May ‘Know’ About Marijuana That Aren’t True. Stoned drivers are safe drivers. UK cops are testing for "drugged drivers" despite studies which show stoners drive safely. UK cops are persisting in introducing a series of roadside tests for stoned drivers, despite a study released by the UK Transport Research Laboratory in August 2000, which found that pot-smoking has a minimal if not beneficial effect on driving performance.
The government-funded study was launched under pressure from anti-drug and driving groups, and was an embarassment to the British Ministers who had expected it to support their anti-stoned-driving campaigns. The British study confirmed the results of a wide variety of research into stoned driving from around the world: A 1983 study by the US National Highway Transportation Safety Administration (NHTSA) used stoned drivers on simulators, and concluded that the only statistically significant effect associated with marijuana use was slower driving.
Roadside testing Those who fail any aspect of the test must provide a blood sample for drug testing.
