OK i havent used a vaperiser before but i made a lightbulb one and basiclt put the weed in there (just a little bit), heated it with a lighter untill what looked like smoke started to fill up the bulb, then i took the cap off and inhaled the smoke and teh weed that was left in there was realy dry and crumbeled when i touched it and smelt kinda like realy dry grass. Problem is i dont feel anything at all, and if i had plain smoked the weed i put in the vap i think i would have been able to at least feel a slight change. Btw i did have a cone about half an hour before that...
