Legalization of recreational cannabis has seen usage rise by 20 percent, according to new research on America’s rapid and risky experiment with a drug that can be damaging — and even deadly — for young people.
University of Minnesota researchers say the frequency of pot use in California, Colorado, Oregon and other states that legalized adult recreational use jumped by a fifth, prompting ‘complex questions’ for policymakers.
The research counters other studies that recorded no increased use, and pro-cannabis campaigners who argued legalization would not boost consumption as black market pot was always widely available.
