That has been my experience as well. Weed users are usually chill, relaxed and don't cause a lot of problems. Alcohol on the other hand is a flip of the coin on how things can end up.
Yes, I am so sick of phones. Just dealt with a lady in traffic the other day who was paying more attention to her phone than driving. I just wish I could get an Office Linebacker to tackle anyone using a phone in a rude manner.
