I do smoke, for around 3,5-4 years now. In the first 2 years, I it did it not because of the addiction, but as a supplementary act. And thats the worst. I had my daily routine, lets say walking home, or sitting in front of my PC, where I didn't really do anything, but smoke. And it's really hard to get rid of it. If my dad doesn't make me angry with his daily BS, I can live without it for days, but since my dad doesn't leave me do my stuff for a single minute, I smoke a pack every day. Not planning to do it forever, it just helps a little in the current situation we are in...
