I certainly did. when I turned 18 I dunno what it was but I just bought a pack of cigs, then got hooked on tabacco for a few years after that. My memory isn't that great but I believe I smoked for 3 maybe 4 years max and the way I quit was I lost my job. I couldn't afford to buy smokes anymore so that was a prime moment for me right there. I'm now almost 33 and wow, I like breathing. Its like any addiction really. Now that I look back it I'm glad I quit
