As of now, get in the gym. I don't care if you get on the bike or you do some curls just give yourself some motivation to better yourself in every way.
Also, I'd search as hard as you can to find a job. Look everywhere, retail isn't as bad as you think if you find a reputable company that has shown to have kindness towards their employees; Walmart is a bad choice.
Hope everything works out man, if you need anything hit me with a PM
I generally smoke anywhere from 2g - 6g of weed a day. Sometimes more depending on how good or bad it is. I also smoke anywhere from 10 - 14 cigs (Peter Jackson or DuMaurier) a day. I smoke a lot Bullseye Cigarillos, Captian Blacks, Colts, Colts Mini, PomPoms, Century Sam, and at least 1 blunt wrap a day. I enjoy a nice fine cigar every now and again. Usually spend a few bucks a month on a nice Romeo y Julieta (mostly for blunts), Cohiba, Monte Cristo, Partagas, Crispin Patino, or whatever else arouses my intrest.
As for the question, I think eventually it does have some effect, but I know plenty of smokers and for the length of time they have been smoking (some upwards of 60 years) they have had a relatively clean bill of health and work out on a regular basis. There was only one person I know of that had a trach done from throat cancer, but 1 out of god knows how many isn't too bad. I think the way some people are going, they have more of a chance of getting skin cancer from tanning too much, or liver diseases from alcoholism. Anti-Tobacco and Anti-Marijuana are way, way over-hyped. It hasn't effected my training per-se, but it has deff made me lazier.
To quote Dennis Leary "They could come in a black pack. Call them "Toumers" and smokers would be lined up around the block for 'em. What's the new law now, you need to smoke in your apartment, under a blanket, with all the lights out? What the fuck is that?"
its not even the dieseases that it causes that makes it shit. Its the cigarette breathe. The stained lips and teeth. the stainging on the fingers. I REFUSE to date a girl (she would have to be awesome for me to even fuck her) if she smokes or has smokers breathe.
