More Americans getting high: cannabis study

Paris (AFP) – The number of adult cannabis users in the United States increased by ten million from 2002 to 2014, said a study Thursday that called for better education on the potential pitfalls.

The increase coincided with a general rise in the potency of the popular recreational drug and a growing belief that it is not harmful, researchers wrote in The Lancet Psychiatry.

The findings, the US-based team wrote, “suggest a potential benefit of education and prevention messages” even as many US states are relaxing cannabis policies.

Based on a survey of over 500,000 US adults between 2002 and 2014, the study found that marijuana use rose from 10.4 percent of the population in 2002 to 13.3 percent in 2014 — from 21.9 million to 31.9 million.
