Boo, as an anti smoking, never smoked person who has a bit of a go at smokers I just want to say, very well done, you have started, don't give up giving up, stick with it. I have known several mates who have cracked it so I know how tough it must be. Once you've given up for a preiod of time there is a tendency to think you've cracked it and just have one "socially" etc DON'T! It's trap, I knew a guy who gave up for 2 years, had one cigar and was then smoking Hamlets like they were cigarettes! You can never ever have another smoke of any kind, but you can sniff some passive smoke, that'll help. I really hope you stick with this and well done to you and others above who have cracked the weed!
