Quotes:

"There is some evidence now that taking a single serotonergic agent—say, taking Lexapro—and no other medications that increase the risk of serotonin toxicity seems safe where I am not at this point recommending that people stop, skip, or taper a single SSRI in preparation for a psilocybin session due to safety." [12:20]

"One of the difficulties with making these decisions or speaking with some confidence or authority on the matter is that the clinical trials that have been done largely exclude people with lots of conditions—family history and specifically first degree relatives with history of psychosis and bipolar disorder… So we have anecdotal evidence, we have population based surveys to go by. And so when I talk to clients about this, I speak from a place of humility." [27:30]

"I always emphasize to clients that while we're talking about a specific safety issue like serotonin toxicity, we don't want to trade that for psychological instability and crisis and declare success because we've helped somebody taper off of a medication that seems less safe and now they aren't sleeping, they're agitated, they're depression is worse, their suicidality is worse. So we have to take a holistic approach to this and consider the totality of what's happening with that client." [36:45]

"There are so many different components to trying to set somebody up for success rather than a yes/no, black and white approach [to psilocybin therapy]." [48:44]
