pepper, thanks again for your response.

One last thing: In my plan, I don't think the psychoactivity is the issue. Once I have the THC extracted into the canola oil, I will cook the canola oil into brownies. The THC will become psychoactive then. The question is: will the THC, not in a psychoactive form and without heat, go from the plant material to the oil merely with shaking and patience?

Any more light that can be shed on the above issue would be much appreciated.

I'm going to go ahead and grind the bud to a powder and mix it with canola oil and start letting it sit for a few days. I figure that if this doesn't work at all, and no thc enters the oil, then that means the THC is still in the plant matter, and so instead of throwing away that stuff after straining I will keep it and use it later. (with heat)

I'd love any more comments and suggestions. Thanks.
