Well I've been using weed since the 80's and have done just about everything.
Smoking while driving is like drinking a beer while driving. If you start off with no booze in your system and just limit yourself to one beer, you are still breaking the law. Same if the backseat passengers drink--makes no sense really but thats how the law is.
Yeah vap pens are way better then smoking a joint, joints stink, you can smell one from pretty far away.
As for my medical use, nope, I don't have cancer, aids, etc. I just have longterm pain from old injuries and I hate pills and alcohol, weed works better for me and lets me live a happy normal life all day and all night long. I bike, swim, stay activate and in shape all year round .. Its easier to get approved here in Michigan for medical use, we got like 130,000 people signed up in Michigan. I believe there is only around 50,000 people in all of Canada approved for medical use. So maybe I don't understand with needing to puff every so often,
