I have a progressive disease that involved deterioration of the lungs. So I MUST keep my lungs in tip top shape. I vaporize marijuana or I ingest it. These edibles that i consume aren't made by me. But made by a legit medical bakery. I plan on getting a type of device similar to the Volcano Vaporizer. Vaporizing (the true form of vaporizing) is extremely safe on the lungs, it may be the tiniest bit harmful. But from what I've read its 100% safe, like smoking an natural ecig or something like that. I don't understand how you're sometimes prescribed it. States require you to get a medical card that lasts a year. Its not like an actual medication where they'll give you a gram a two for the next week or whatever.

I won't lie, i do smoke it on occasions. But in all honesty, the occasions that i do smoke it would have little, if any harmful effects on the lungs. its only harmful if its smoked on a weekly or daily basis. For the first few months i didn't have any money for a vaporizer, so i smoked it. But then when i got the money i immediately bought a vaporizer.

i view smoking marijuana similar to smoking cigs. not as harmful, but still very harmful. marijuana contains tar and other bad adulterants when its smoked, vaporizing basically heats up the cannabinoids to their boiling point. I've researched a lot about marijuana before getting the medical card.
Edibles digested by the liver change THC to 11THC (not delta 9, but 11 hydroxyTHC) . but eating normal, "unactivated" marijuana will barely, if any cause a high because it isn't THC. Its THCA.
