I think alot of smoking is the habit you get into it somehow almost always to it seems social people you work or go to school with smoke so you end up doing it with them. When I was in Air Force tech school I messed around with smokes for a bit and off and on in highschool but I guess it never became a habit for me they made the daily PT much harder so I just ****canned em.But I can very easily see how that is the start point for many.
My roommate decided that he was gonna cold turkey so he stood over the balcony and smashed his whole pack he told me to keep him from going to the smoke pit when we where on duty and I did. What got him though was when we went out drinking we where stationed in Germany and at the time smoking was allowed in bars and they where thick with it.My buddy hooked up with this german chick and she had smokes and my friend being drunk at the time took one I was getting up with my girl to leave and I told him not to smoke one or hed be right back at it. And he did relapse a few times but he did finaly pull through it. The thing many military people get hooked on is dip/snuff though you are not supposed to use it on duty it is easy to hide that you are using just an empty soda can is all you need or nothing at all if your outside driving a truck or something and if someone calls you out many will simply swallow it. Based on people i knew and saw in the Air Force Id have to guess that about 30% at least military members use it and some also smoke it matches up with an AFN news segmint I saw a few weeks ago(if you have the Military Channel you can see the daily AFN news its in the afternoon some time) about the growing number of military snuffers.
Id say the number one thing is first figuring out what part of smoking you are addicted to(or parts) some it is the nicotene for others it is in the hands and having the cigarette in them and I suppose for some its a related habit like standing around with other smokers/coworkers or not feeling relaxed unless you have smoked.Also be careful not replace one addiction with another that happens to people sometimes. I have heard that snuff is the worst thing you can use nicotine wise as it gets into your blood stream much faster than via the lungs.
Anyway if you are wanting to quit go for it just realize it may not be very easy but the health benafits are well worth it. One of my very close childhood friends his father quit sadly the damage had already been done he got lung cancer and it was pretty advanced but they removed it however the cancer had already spread to his brain in a place that was in-operable it was terriable becasue he lived for about a year but the tumor was growing and of course it was effecting his brain function so his personality was changed at times.He was 45 I belive when he died he had started smoking at 14 or 15.The sooner you can stop doing the damage the better as AVG said about cilla growing back that is damage being repaired and the "muck" is the cilla being able to clean your lungs out again i guess it is your body saying you stupid ****nut whay the hell did you do that **** in the first place? Also it is very nice to be able to breathe fully COPD is anti-breathe which to me is very lame.
