LSD, magic mushrooms and ecstasy are well known street drugs not usually associated with medical treatment.
But that could be changing.
In a new article in the Canadian Medical Association Journal, researchers examine the therapeutic effects of these substances on people with mental disorders, ranging from addiction to depression, anxiety and PTSD.
The research suggests some illegal drugs may have beneficial medical effects.
MDMA- assisted psychotherapy has shown promising effects for treating PTSD in The U.S. and is currently being studied in Vancouver.
It was research that was pioneered in the 1950s and conducted through to the 70s, but eventually fizzled due to the condemnation of illegal substances and the subsequent war on drugs.
"As decades have worn on and we face continued challenges with mental health and limitations of the existing paradigm and existing treatments, it is reemerging as an area of clinical interest," Dr. Evan Wood told CBC On the Coast's Stephen Quinn.
Wood, a professor of medicine at UBC, is one of the study's authors.
