heres a thought but just make oil or some kinda concentrate like bubble, personaly oil is best for ingestion and use that. no heat, no extract just pure.

look up BHO on you tube and learn to be safe with Butane and use only at least 5 times refined tane, no cheep stuff, lots of dangers in the cheep stuff.

I think this is what you were going for the whole time? the Cure?
