Laws against cannabis have failed to cut its use around the world and have led to policies that are intrusive, socially divisive and expensive, according to an international group of drug policy experts.
In a book published on Tuesday looking at cannabis policies, the experts said that, while the drug harmed some users, it had only a modest effect on society, where cocaine and alcohol were potentially more damaging.
"It is time for governments around the world to readdress cannabis policy," Peter Reuter, a professor of public policy at the University of Maryland in the United States and one of the book’s five co-authors, told Reuters in an interview.
