Prohibition refers to the act of outlawing or forbidding something officially in law.

In the UK, cannabis was prohibited by the Dangerous Drugs Act in 1928 which made it illegal for people to consume, purchase or cultivate cannabis. Doctors were still able to prescribe cannabis for medicinal purposes up until 1971, when the Misuse of Drugs Act criminalised cannabis completely. In the UK, this prohibition continued until medical cannabis was legalised in November 2018.
