One of the things that has always annoyed me about weed advocates is that they rarely, if ever, mention any of the negatives. For example, it can't be all that healthy purposely inhaling burning material into your lungs. Does it have the chemicals that tobacco has ? No but it is still burning a plant matter and putting that smoke into you. It wouldn't surprise me if over time as pot becomes legal across the country, big business starts to work it's way in and start treating like tobacco. Having said that, I realize that there are many positive properties in both the CBD and THC sides that make edibles and tinctures desirable for many and you can't argue that the societal effects are anywhere near what they are with alcohol.
