Unfortunately,yes. But I smoke a lot less than I used to. Just a few years ago I was like you (yeah,like a chimney…hehe) but now I only smoke 10 maybe 15 a day. BTW…tobacco is a REAL drug,and probably the most addictive drug in the whole world! The only difference is that one is legal,the other one is illegal. (at least in most countries) Oh,and the fact that tobacco does not render your brain to a useless piece of junk. :))
