I tend to be a bit of both. I'm whatthey call a "social smoker" I tend to smoke only after Ive had a few beers. Normally bludged ones. I was on a long train journey once atleast 5 hours long. The people I were travelling with generally all smoked but we ended up in the non-smoking wagon because we didnt want the stench. Anyway I found people so tense in the wagon. We couldnt make a noise without a dirty look. Me and one of my friends went to the smoking wagon for a quick puff. the general mood of everyone on there was completely different. Everyone was so relaxed. It's almost like they were sedated.
Verdict: smoking maybe bad for your health but in a sense it's a good way of relaxing. Maybe because these smokers have something to take there minds off things
