Age 64. Smoked pot in late 60's, 70's, 80's, but not as much as in the 60's. I'm on bi-polar medications, and my psychiatrist said alcohol, pot, or any other drug would interfere with my BP medications. I gave it all up, including cigarettes 2.5 yrs back. My medications are working great, and would not want to mess it up.

Then for the very shocker, Youtube - Lung Damage
