Missouri Republican proposes adding access to LSD, MDMA, peyote, and psilocybin as treatment options


Wednesday, Representative Michael Davis, R-Kansas City, proposed legislation that would modify Missouri’s existing ‘Right-to-Try’ law.

Right-to-try aims to allow patients who have been diagnosed with life-threatening diseases or conditions who have tried all approved treatment options and who are unable to participate in a clinical trial to access certain unapproved treatments. Right-to-try permits those patients to have access to investigational drugs.

HB 2429 would expand access for right-to-try to not only those with terminal illnesses but also those who are afflicted with debilitating or life-threatening conditions as well. Missouri has had its own version of right-to-try since 2014. Federal approval in the form of the 2018 “Right to Try Act,” has since opened more doors and created new treatment options for patients.

Accordingly, Davis’ proposal would also expand the list of substances those patients would have access to. Schedule I drugs such as DMT, ibogaine, LSD, MDMA, mescaline, peyote, and psilocybin would all be added as treatment options.

Davis’ proposal reads, “The offense of possession of more than ten grams but thirty-five grams or less of marijuana, any synthetic cannabinoid, 3,4-methylenedioxymethamphetamine, diethyltryptamine, dimethyltryptamine, 5-methoxy-N, N-diisopropyltryptamine, ibogaine, lysergic acid diethylamide, mescaline, peyote, psilocybin, or psilocyn is a class A misdemeanor; except that, any such possession shall not be considered an offense if the possession is in accordance with the provisions of section 191.480.”


Davis filed the same bill in 2021, HB1176, the bill was referred to committee but never reached the floor.
