The hot knifes are a good idea. They are the ultimate vaporizer.
Its the only method i use at home. The thing i do is stick the knifes
in the element on the stove and use a 2 liter coke bottle cut in half.
to catch all the smoke. A straw doesnt realy work for me.
I smoke like 1 gram a day and get stoned all day doing hot knifes.
It conserves bud.
