Im just greedy though and plenty of people are. Used to love a smoke (obviously) but now I hate it.forgive me but you sound a little self-righteous. I smoke anyway so that gets rid of a lot of your negatives, i actually found it helped me sleep better, cost me very little as i grew my own and ive had a fairly successful life these last 30 odd yrs. Like i said it wont suit everyone just like drink doesnt you have to have the strength of character to keep it in check especially when you're sitting on a bin bag full. As for f***ing your brain i think the gear i was using in the late 80s early 90s was much more harmful
