yes that's my concern (drug interactions) I've seen curious users mix all kinds of things without checking first, and they've never had any experience in doing drugs (either legal or illegal) and end up worse off

In terms of reactions, I think it varies from person to person. Generally speaking though, hallucinogens aggravate existing psychotic disorders. If you suffer from PTSD/depression it's not a psychotic disorder (so it's relatively safe for you to take).

Curiously enough, a subset of patients suffering from ptsd/depression/anxiety don't experience the euphoria associated with amphetamines. I'm sorry if I didn't word myself clearly enough
