I would go as far as to say it is good for you!
Saw a study years ago (long before the days of vaping) which compared the lungs of pure green smokers with joint smokers (green/tobacco mix) & non smokers. And it turned out the people who had the healthiest lungs were the pure green smokers! So... it pays to be a smoker if you're smoking the right thing ;)
Puff puff pass...
Well I honestly wouldn't know, I've never even tasted tobacco, not once. I don't know why, actually, it just never happened. Which is fine with me!
Puff puff and pass again...
