Washington DC legalises all forms of Cannabis in what is seen as the most controlled legalisation laws to date. Under the law, residents can grow and possess Dagga in their homes, but can’t smoke it outside. Cannabis shops are banned and there is to be no public smoking –  be it outdoors or in a public space, night club, private club or restaurant. Penalties for violating the new city rules are so stiff that there are unlikely to be many conscientious objectors.
