I have been smoking weed daily for over 20 years, my lungs are in great shape.

I quit smoking tobacco 10 years ago and haven't had any lung issues since.

I am also a computer programmer and cad\\cam designer for over 20 years, so the lazy airhead stoner stereotype a lot of people are bringing up is BS too.

Yah, my lungs are fine too, but it’s just a fact that something happens to your lungs when you inhale something other than air. That doesn’t mean we’ll ever see any actual signs of lung issues though.

I definitely can’t smoke daily though. My short term memory goes to shit.
