I hope I can be like your grandma! I got about 30+ years of smoking to go!My grandmother is in her late 70's and still smokes a few times a week. Shes a very healthy woman! As a matter of fact I give her some of my homegrown whenever she comes to visit.
Look up Irv Rosenfeld on youtube. US Government Medical Marijuana user for over 20 years and guess what, his lung capacity is at 108% after smoking that many joints a day for over 20 years.sorry dude you have to show prof of this one. lung capacity does not mean your more healthy I'm in med school and weed puts more tar in your lungs than cigarettes due to there not being a filter .
