Mango. There is one other point, apart from the fact it will probably kill you, and that is to non-smokers you stink! It doesn't matter what smokers think, they and their houses actually smell dreadful to others. My wife and I will not have smokers in our house and we won't visit theirs..
Like most workplaces, LTCC has a non-smoking policy so those on the weed have to go to special rest-rooms or stooge around outside in the rain whilst they satisfy their cravings. On return to the work place they STINK - their breath stinks, their clothes stink... Think about it long and hard.
I wish you luck. Like most kids, I had a few fags at school but the taste was so dreadful I packed it in.
