I see no problem with using dry weed to infuse or in edibles. Whenever I decarb my buds in my Ardent, they come out very dry but are perfectly fine as edibles.What to do with the world's driest weed? Tempted to crush it like oregano and make a batch of butter for baked goods. Taste isn't an issue since it's got none!
Aroma is there, and I'm betting that much weed has to have some THC left in it.
