Study Finds Some Scientific Consensus on Marijuana


For decades, a constant flow of research into the health impacts of marijuana has painted a confused picture of how exactly cannabis effects the human body and mind, but a new review of the last 20 years of research finds there is some academic consensus.

“There are consistent associations between regular cannabis use and poor psychosocial outcomes and mental health in adulthood,” writes Wayne Hall, in the latest edition of the journal Addiction.

Hall, a professor at Australia's University of Queensland, examined epidemiological literature published between 1993 and 2013.

He notes that those who drive under the influence of marijuana are twice as likely to be involved in an accident.

About one in 10 daily marijuana smokers become dependent.

While only about seven people out of 1,000 from the general population experience hallucinations and delusions, Hall points to a study that finds double, or 14 in 1,000 marijuana smokers, experience those symptoms.
