I used to smoke marijuana for a month everyday multiple times and i quit it within a day and i never smoked again even though they called me everyday still to smoke with em. I used to smoke cigs for 3 months and i stopped and it took me 2 days to forget cigs. I used to drink everyday last month and i stopped and i just dont feel addicted to anything? But lots of my different friends are addicted to one of the 3 things i used to do? This means i have strong will right or does it ?
