I smoke daily and I would not be happy to give it up at all I agree with you on that ..... But it has its ups and downs and it is better than burning through percocets. Judge if ya want but walk a mile or so they say

. Also ask your friends who drink coffee or a lot of caffine to give it up and see what happens ? In a classic sense those people are addicts but they will get over it in a short span and it isnt going to be the same as kicking dope or booze at all which hook into a person in way worse ways.
I think those peoples enthusiasm is mostly harmless most folks arent burn a half a day smokers and no one seems to bat an eye at the beer wine whiskey enthusiasts etc . Let people enjoy themselves.
Personal liberty is always a good thing and the more the better. Folks should be free to decide if they wish to compete in 3 gun on saturday night or get high and giggle at the ceiling on the couch and as Rogan would tell you you can get addicted to anything including cheese burgers.
Im extremely pro pot but I will be honest and say that my entire life revolves around the plant as I am a heavy smoker and work in that industry just so you know where i am coming from. Its given me a real life and allowed me to get myself out of the hood so it is very hard for me to see the negatives as anywhere close to the positives
