Isn't that exactly what 10's of millions, if not 100's of millions of people do every day all over the World, when they drink alcoholic beverages?
Drink until they are drunk and unable to walk straight and/or talk coherently?
Except for a very minute minority of people, those who smoke marijuana don't cause trouble after they get high or zonked, as opposed with those that drink alcoholic beverages!
As a non-smoker and a non-drinker, I would rather be with a group of 100 people who smoke marijuana and get zonked than in a group of 10 drinkers!
