I'm not going to tell you to pray, or that weed will make you crazy, or that you're a bad person for smoking, or any of the the other health class nonsense. I've seen alcohol destroy way more lives than weed. I don't smoke, I quit about 7 years ago. Some people smoke and it's fine for them, but if you think it's time for you to quit, you're probably right. Best of luck, just don't lose sight of why you're quitting. After about a month, quitting anything becomes alot easier, whether it's weed, cigarettes, alcohol, overeating, whatever. Just stay on top of your game.
