I own a vaporiser and I was given/lent one.

The Blue Meanie was the one I was given and it literally cooks the weed. Not very good if you are trying to escape 'smoke'. That was quite a cheap vaporiser that will get you high (if it doen't cook your weed first).

I didn't give up with vaporisers even though the blue meanie was a little on the crap side.. I then bought a Vapureyes. By far not as expensive as the volcano but in my opinion worth the neat pricetag. Nice and small and usable in the car as it runs off 12V. If I wasn't always on the move I'd vape all the time, but joints are just more a convenience.
