I'm not making a moral judgment on smoking. You guys have done that for yourselves. I'm just saying it's stupid, because it has no benefit whatsoever to you or your health. You wanna blow off some steam? Get some exercise.
Gaming is stupid, because it has no benefit whatsoever to you or your health.
Reading fiction is stupid, because it has no benefit whatsoever to you or your health.
Eating cake is stupid, because it has no benefit whatsoever to you or your health.
Drinking is stupid, because it has no benefit whatsoever to you or your health.
etc etc.
Get off your high horse. Lots of things are bad for you and most of said things are highly enjoyable, that's why people do things that are bad for them. Personally if the choice is living my life without doing anything dangerous, or dying a couple of years earlier, I will happily start digging my grave. Living without joy isn't living.
Oh, on topic, yes, about half a pack a day, 3-6 joints in the weekend and cigars for special occasions.
