How can i smoke without getting addicted?

i smoked 1 cigarette with my friend and it was my first time and i didn't mind it because normally i hate the smell but this time i really didn't mind it. i don't have the craving for cigarettes but i do still want to continue to smoke from time to time but i really don't want to get adictted. and i know smoking is bad especially since im asmatic but when i do smoke i only smoke 1 cigarette
