I've toked for 40 years- my lungs were a mess. It took just 2 weeks after getting a vaporizer for them to be clear. No morning cough! If you are worried about your health, vaporizing is the way to go! Plus, vaping doesn't have that tell-tale pot smell. In fact, there's almost NO smell. The pot is still there after vaping (unlike smoking), and it makes passable brownies. To be honest, they are not as good as if you had used bud, but they get you quite pleasantly high. So, you get to get high twice on the same weed. Get a vaporizer! I got a little Vapor Brothers after doing a bit of research. I finally bought from discountworldonline.com I got a receipt, which I expected and then a notice stating it had been shipped about 48 hours after my order (I was surprised at the fast service- I expected about 4 days to ship it). Arrived in the mail about a week after I ordered (there was a Sunday in there, too). Always a bit paranoid about chemicals, I ran it empty at high for an hour. Vaping some of my homegrown for the first time was heavenly!
