People should be free to take whatever soft drugs they like.
We will not win the war against drugs with prohibition, just
look at when alcohol was forbidden in United states during the 30ies that led to the rise of Al Capone and similar mafia organizations.
The solution is simple make it unprofitable for criminal originations to manufacture drugs by making them legal.
The current drug laws are also hypocrazy as long range bomber fighters are allowed to take light doses of Amphetamine to stay awake during long missions. So the state are allowed todo what its citizens are not allowed todo.
