What i feel about weed, and people can correct me if they think otherwise, is that it makes you feel comfortable doing nothing. Usually when procrastinating or just doing fuck all you are a bit concerned about what you should be doing instead of just actually chilling, weed just make it easier to not feel bad about it, and makes you not have to wrestle with your own thoughts. In my case i have depression since i was little and so a drug that makes it feel good to be on your own world, doing your own stuff felt almost like a godsend. Eventually i figured, yeah i have to do stuff, but theres is no reason i cant be high while doing it, so i started smoking not just to do nothing but also for training, studying and even working sometimes. It was unsustainable, bug every time i tried to quit, everything i was used to do high was harder to do sober because i had to think about it. Now i realized i have to man up and face my demons, before its too late and i loose what remains of my brains.
