I was thinking today about the arrests of weed smokers

What crime has a person under the influence of Marijuana ever commited besides smoking weed. I have shoplifted a couple of times in my life but never when I was high, not because I was scared to, but because I ponder about how if a steal that how much trouble it causes other people. I have no idea how anyone would attempt to hurt some else when high because it puts you in such an uplifted and happy mood, you just love everything. So why are marijuana users criminals?
