Salvia divinorum, a psychoactive plant, is legal in most countries. Exceptions, countries where there is some form of control, include Australia, Belgium, Brazil, Canada, Denmark, Estonia, Finland, Germany, Iceland, Ireland, Italy, India, Japan, South Korea, Norway, Poland, the United Kingdom, Ukraine, Slovakia, Spain, Sweden, Vietnam, Armenia and 33 states and territories of the United States.
In the United Kingdom, following a local newspaper story in October 2005, a parliamentary Early Day Motion was raised calling for Salvia divinorum to be banned there. However, it only received 11 signatures. A second Early Day Motion was raised in October 2008 attracting 18 signatures. The Advisory Council on the Misuse of Drugs, the independent body that advises UK government on drugs, was asked to investigate further. On the 28 January 2016, the Psychoactive Substances Act 2016 was passed. The act came into force on 26 May 2016, across the entire United Kingdom, making Salvia illegal to possess with intent to supply, possess on custodial premises, supply, import for human consumption, or produce for human consumption. The two sponsors for the bill were Conservative House of Lords member Michael Bates and Conservative MP Theresa May.
