even if you do get an effect, it will be shortlived and in alot of people they get sick...

eventually it will wear away for good, no matter how much you increase 'dosage' it's a horrible habbit and you're hearing this from a 16 year smoker....

doesn't take long for that possible lightheadedness to go away and be replaced by pure addiction...

it's not worth it dude, do yourself a favor, take those cigarets, break everyoen of them and put them in the trash...
