My transition into vaporizing was similar... went from getting shitfaced on the fattest j's, blunts, and bowls I could suck down, to where I am now. Seeing my friends throw 2g+ of high grade into a wrap nowadays makes me want to go, "NOOOO! We could of all been high for days off of that". Of course, they don't understand. And also like you mentioned, I get high off way less product than I ever thought would be possible. All I have to do is load up what would have been "one big ass bong rip" into a vaporizer, and I can stay elevated for most of my day with no burnt out comedown feeling.
