Hi,
A while back I bought a vaporiser-not a very good one mind (they are very expensive), because i was curious and felt guilty about my lungs, as I was smoking quite a lot back then.

You don't need much in the vaporiser for it to really hit you. Because it is only a fume as opposed to smoke you can inhale deeply and hold it for a few seconds-it soon gets you zonked.

I get a nice body high using a vaporiser I don't get with a joint or pipe, and if I have a bit more it i often quite psychedelic-colours, patterns, shapes in clouds, moving images on carpet etc. If you overdo it though your pulse goes way up. For me anyway, there is definately a difference between the high you get using a vaporiser, compared to using a joint or pipe.

Not only is it better for your lungs but you need a lot less weed for the desired effect.
