hey, I read on a site that seemed like it was legit (but had no scientific proof) that you can just put finely chopped cannabis buds in a jar with canola oil and wait ~24 hours (shaking periodically) and then pour it through a cloth to separate the leafs from the oil and you'll be left with canna-oil with THC. The thing that struck me as odd is that this mentioned that you didn't need heat at all. Of course I would be heating it eventually to cook the brownies but is this true? Can anyone back this up? Can I really make canna-oil without heat, and just by waiting? Thanks.
