I was on a 6 month cigarette smoking stint freshman year of highschool after trying my first joint and cigarette as a "congratulations for graduating middle school" during summer with some friends in another state. I didn't know where to get weed back home, but a friend's brother could buy my the cigarettes, so I stuck with them. I smoked about 5 cigarettes per day, sometimes more if I was stressed out.
I was caught smoking behind the cafeteria during lunch period by my English teacher. Ironically, he was going outside to smoke too, which he was not allowed to do while "working". He told me to put it out, get back inside, and not let him catch me out there again.
I realized then, I can't go through life trying to hide this habit I knew was discussing and was going to give me lung cancer anyway (we had an assembly about the ill affects of drugs and alcohol the second week of school and it did scare me, as intended.) So, I had my friend's brother buy the Nicorette step 1 patches. With the patches, my own willpower, and support from my two best buddies, two weeks later I had my last cigarette at 11:46pm on December 7, 2003.
In college, I've socially experimented with hookah, tobacco pipes, Black&Mild cigars, a bunch of "natural" herbal stuff, vaporizers, and weed. I loved them all, but have quit everything but B&Ms. (I would smoke weed if I didn't have a job that drug tested.) About twice a month my roommate and I split a B&M after a night of drinking as we talk philosophically about random stuff.
I've probably spent about $2500 on everything I've smoked to date. At this point I spend $5 on a 5 pack B&M every 4 months. At $15/year it would take me 33.34 years to spend the equivalent of an iPad ($500). How much money I would save if I gave up alcohol is an entirely different story!
