I can't say, as I've never been in a situation that traumatic. From as much experience with memory as I have (mine is terrible anyway), I'd say chances are that I would opt not to take that kind of a drug. If I am going to fundamentally alter my mind, I prefer to do it through my own devices (mind over matter, or mind over mind if you will). And no, smoking weed is not fundamentally altering one's mind. It goes back to normal later.
