"Take pot away from the user and he's pissed off for a few days" :^)
This is true, to some extent. I have a friend who is actually addicted to marijuana. You can tell when he is in desperate need of a hit.
Illicit drugs are destructive at any level.
I absolutely agree. This last until he sleeps off his buzz. Improvement in temperament will be marked with each sleep/wake cycle.
If he remains a jerk after a few days he's probably a better person when he smokes the stuff. Don't knock it.

I used to work with a guy who was impossible to be around unless he had gotten lucky at the bar the night before. Then he was a great guy.
