Introduced earlier this year, Senate Bill 519 would allow the possession and sharing of certain hallucinogenic substances such as magic mushrooms, MDMA, LSD, ketamine and ibogaine for those 21 years and older. Notably, however, the legislation does not decriminalize sales of such drugs.

“This is a big step for this legislation and for our movement to end the war on drugs and to take a more health and science-based approach and to move away from criminalization of drugs,” [state Sen. Scott] Wiener said in a video posted on Twitter.

Research has demonstrated that psychedelic compounds combined with therapy can be effectively used to treat an array of mental health conditions, including anxiety, depression and post-traumatic stress disorder, as well as substance use disorder, according to SB 519’s text.
