you have nothing to be ashamed for my friend, jordan has the best "muassel" it's hard to resist
I smoked cigarettes for 30 years ,i have not had a cigarette for over 10 years,i found it was easy to stop thank goodness,i started smoking in the Army as for me nothing really to understand apart from i am a better healthier man for not smoking.
I just hated the smell that would come off my mouth the next morning after a night of heavy smoking, that alone was the reason i quit.
I'm proud to say I'm not a non-smoker. Non-smokers are the scum of the Earth! (Just kidding, that's an old Bill Hicks line ) As for the smell, well, e-cigs are the way to go - water vapor doesn't produce a flame or smell!
I mostly just smoke Marlboro menthol Smooths, back when I had money I used to smoke stogies and pipe tobacco with my dad a lot as well. Also loves me some pot, but it's harder to come by here in the ultra-conservative part of Texas.
Never drink and smoke any more, though. Used to get amazingly trashed on massive bender binges of like two packs of smokes and tons of beer in a single night! Learned the hard way to never do that again!
