Psychedelics and mental illness
I know a lot of cannabis fans (and count myself as one). Very, very few of them acknowledge that cannabis affects people inconsistently; one person's reaction to it can be very different than others. This is inconvenient for calling it a "medicine" so let's just ignore it.<p>Psychedelics are even worse. The same dose of the same drug can produce wildly vary effects in the same person depending on factors we have trouble nailing down. "Set and setting" and the Erowid wisdom are all very well, but they are barely enough to describe the area and edges of the therapeutic window in a general way. <i>Your</i> trip, today, is still going to be an experiment.
