1976 CE
The Netherlands decriminalizes cannabis

Under the 1976, the Dutch law, possession of marijuana remains illegal but low-level possession is tolerated. A system of “coffee shops” has developed. These cannabis bars can sell small amounts for take-out or smoke-in to adult patrons. One of the reasons for this practice of toleration is to prevent users of "soft" drugs from coming into contact with street dealers who also sell drugs like heroin or cocaine. The national framework allows local governments to implement the policy with a fair degree of freedom in terms of criteria and enforcement. Most cities, other than Amsterdam, do not allow sales to tourists.
