cook the weed and oil only long enough for the weed to turn. once the weed goes brown and then black, there really isnt any more you can draw out of it.

i think maybe 10 or 15 minutes on pretty high heat tops. it wont take that long.

start out low heat.... then increase. as the heat increases, the oil will sizzle, and the weed will go from green to brown.

thats what you want. you can stop there.... or go from brown to black. once it goes black... its done. there is no point in cooking it more.

whats strange is that i found when i stopped at different cooking times.... in other words, sometimes it was mostly brown still, and other times it was black....

it gave me a different high. even when it was the same weed.

so do some expierementation. but you at least need the weed to turn brown. if the weed is still green, you wont get high at all as far as i know.
