I have been around numerous people who smoked marijuana. Quite
frankly I grew up around people who grew and smoked it. When they had what they called “seeding” parties after a harvest, I never saw anyone act like any of those people. (this included about half the people in the town I lived in) During the seeding parties we usually had a fish fry and the adults sat around seeding and smoking. Likewise, when I smoked pot many years ago, in my teenage years, I do not recall ever acting that way or anyone I knew acting that way. I recall laughing at funny stuff such as, Bill Cosby’s comedy tour, which we had on video, (I would have done anyway because I loved his comedy tours) eating a lot of junk food, and being very thirsty, because I had cotton mouth.
As for the part of the movie where the fight breaks out over some guy trying to rape Mary, that’s another thing I have never seen happen. People may get sexual but not so sexually aroused that they try to rape people. I also have never seen high people get violent, ever.
I can’t forget to mention the part about Jimmy hitting the man. I cannot say that I have ever seen a high person ever drive erratically. They tend to be more relaxed and drive slower, however, that is only in my experience. Not to say they couldn’t hit someone because their reaction time is slower, but being an erratic driver is unlikely. I expect that type of behavior out of someone who drunk.
