If you’re particularly lazy and want to check how a plant is doing you can even just microwave to activate it. put it in a glass cup with a damp paper towl under it, cover with a second damp paper towl, cover in plastic wrap except a small gap like you’re making a microwave dinner. Cook for a minute at a time on 20-30% power and let the steam release between cooks. Do that 2-3 times then remove nug from container and let it sit a few minutes on a plate or something.
I can’t speak for other countries, the EU banned it a while ago, but up until very recently a lot of citrus drinks over here in the U.S. used a chemical called Brominated Vegetable Oil as a stabilizer/emulsifier I think? So at least in the U.S. there can be fats in some sodas. Maybe enough for the THC?
