Cigs are useless, the main effect is probably oxygen deprivation from the CO in the lungs. Makes you a little tipsy.
People that can't drop cigs, there's some problem there. And if pot is easier, you should certainly never need it again.
Again, God help you.
Pot is MUCH easier to go w/o than nicotine...when I smoked cigs, I couldn't go more than 4 hrs w/o getting "that feeling" (craving another one). Things eventually became almost unbearable after that, & the ONLY thing that kept my addiction from rearing its ugly head was another cig.
But w/ pot, if I go a week, or even a month or longer, it doesn't bother me. It's that simple!
