Look, not everybody gets addicted to pot, in fact most folks don't. But it's psychologically addictive like everything chemically active you put in your body, and being constantly stoned because you're addicted is a miserable way to live.
I know, because I've been trying to quit all year. I've failed twice since February and I'm on my third go of it right now. And I only smoked a half-ounce a week for a year or so. That's probably a lot to the people reading this, but it's really not much as far as potheads go.
I'm sick of thinking so much slower than I know I can, being so much dumber than I used to be. I can't do my job nearly as well and I take pride in my work, so being too dumb to do my job has been really upsetting. I almost wish I were still addicted to cocaine, because at least then I kicked ass and took names when it came to thinking/analyzing/working in general.
I'm tired of being too lazy to leave my apartment all weekend, of the food I eat when I'm stoned, of not being present around my friends, family and co-workers, of needing to smoke when I wake up because it's so uncomfortable to be lucid. My motivation to pursue new ideas, to eat healthy and go to the gym, to meet new friends and pursue new women is all through the floor. My body desperately wants pot right now and I'm anxious and depressed as hell and my body is tugging at me to reach for any alternative, like alcohol or cigarettes.
Every drug taken to extreme can seriously hurt your life. Even weed. Stop trivializing it because you smoked a few joints in college.
Edit: and now I'm slowbanned, for sticking up for myself when someone kicked me while I was down. Time to roll a new account, I guess.
