  • 12:00 PM - 2:00 PM


Our longtime colleague friend and April sponsor Joe Considine, along with John Puls, LCSW will update us on cannabis abuse research including the use of the Marchman Act to force involuntary treatment, pulling many back from the brink of cannabis-induced psychosis. 


Cannabis is the most used substance nationwide after tobacco and alcohol (NIH.   Approximately 16 million Americans report regularly using cannabis (NIH). The vast majority of cannabis users begin using during their teenage years (NIH). Problems have arisen with the broad legalization of pot, including a failure to account for increased toxicity and the dangerous effects on early teens and young adults. Rapid increases in anxiety, paranoia, and psychosis-related hospitalizations from cannabis are causing alarm.

Cannabis has been shown to increase early-onset schizophrenia by 3 years.  As well, the spectrum of psychotic disorders, including schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, delusional disorder, and substance-induced psychotic disorder have been stark and concerning.  Cannabis is found to be linked to the onset of bipolar disorder with psychotic features and increases in the onset of symptoms of mania.
