I sense judgement from you towards anyone who has found utility or enlightenment through mind-altering drugs.

Just because I'm smart doesn't mean I stop reading. Just because I am fit doesn't mean I stop running. Just because I'm happy doesn't mean I can't dabble with new mental models.

And finally, to clarify the OP's statement: "Mind in the right place" doesn't mean being perfectly happy or without stressors/depression. To me it suggests someone doesn't have mental illness or suicidal tendencies.
