I don't smoke cigarettes anymore, but when I did,.. I smoked Marlboro Red 100's in High School - then out of High School I smoked KOOLS. I did quit. Then smoked again. Then quit again. This time I managed to stop smoking altogether. I think I quit mostly because I stopped drinking. I used to love to smoke cigarettes when I consumed all that alcohol, and without it, smoking just felt like a chore. And I ended up smoking more to balance it all out. Eventually, I didn't like the way it all made me feel, my husband was also concerned for my health, so I felt that it was time for a change.
I smoked weed a few times in High School because of peer pressure and what I was going through - but I didn't find it all that amusing or fantabulous, even with friends. I smoked it again as an adult, and didn't really see the need. Then again - my life isn't exactly high stress, high responsibility.
