I started smoking in my early / mid teens just to get wasted. Back in those days everyone like to get in an altered state by drinking or smoking or both and just hang out and laugh our asses off at stupid things. As the years went by, it became a habit. Not an addiction like cigarrettes, just something that I did on a regular basis. I'd smoke a bowl or four every day. I certainly stopped enjoying it as much as I used to in the early years which is why I've just given it up. It's just not as fun as it used to be.
No regrets though
