Oven at about 80degC for maybe 10-15 minutes, but it will taste really really bad.

Patience is key when it comes to growing. Why waste all that hard work on growing just to have a nasty smoke.

What I would do, if you want a test smoke, is just take some of the less developed buds and snip them up into smaller pieces. Leave it out overnight and it should be ready by morning for a smoke. That's what I do anyways, and it doesn't taste bad.
