its better than smoking though mate!
i speaketh from experience dude, i smoked for 20 years, the green stuff and ciggies and never felt better after packing in!
the first 6 months of packing in i felt terrible as the gunk was coming off my chest, but after that, no turning back!
heck i even bought my audi with the money i saved!
the only drawback is that i put on about 3 stone and thats partially down to drinking a touch more!
you hang in there soldier and dont relapse!
£7 a packet of fags.............................balls to that
