I've smoked on and off for over 20 years. Quit a few times for work and to clear my head. I never once got withdrawals or pains or the urge to get baked. It doesn't have a chemical hold on you like cocaine or the other drugs. Weed is one of the safest drugs to do. I've seen alcohol ruin lives. I've seen other drugs ruin lives. Never once have I seen weed ruin someone's life. It's absurd to say so.
