smoke the ganja man …… 
I was down to 5 cigs a day when I got busted for growing.
now I’m back up to about 1 1/2 packs a day ….. can’t wait to get off probation so I can again substitute …..seems to be my only workable solution.

btw: Nick makes an excellent point. Back in the day …. (as they say nowadays) …. people died from emphysema and TB …. not cancer.
That didn’t start happening until they started adding the additives to the tobacco.
