Agreed. If I have good herb and I vape it in the Volcano... if I have things to do later on sometimes I cant finish the bag of vapor. And its not because I know I'll be too stoned, its because it hits me right away. I read a study that it supposedly takes 20 minutes to feel the "peak" or full affects of cannabis. I have not read any follow up research or any research besides that one study so I don't know how valid it is but thats a pretty interesting idea.
I've been toking since 1966, started out on good South African weed (Durban poison) in chillums - that was what we did as 13-year-old kids... before school, lunch times, after school, in the evening! Anyhow, I just love being high on good grass. All the time! Never smoked cigarettes or tobacco, until I emigrated to the UK in the late 70's... here, everyone (almost) smokes joints with tobacco, so I joined in for a few years, but really didn't like the tobacco, made my chest get tight, tastes yukky and makes everything smell awful, know what I mean? So I took to smoking a small pipe, managed to find a good source of sun-and-earthgrown grass, and that was great. Then I discovered vaporisers. I love it - the high is excellent, it seems to be a clean and economical means of ingestion, and it's really nice to turn my friends on to it too! Vaporisers rock! (mines a blue meanie - maybe not the best, but it does for me)
