My grandma is sick with cancer and my dad brought her up to Colorado to get some THC dosage! He thinks he is making Tincture correctly right now but I am almost guaranteed he made it wrong. He just put straight vegetable glycerin with a half ounce of shatter (not decarbed, no alcohol extraction or whatever) in a bottle, and let the bottle soak in hot water for a while. He has been shaking it up while it cools down. But I just am worried that he did not make it right, that he wasted a whole half ounce of shatter, and that my grandma will not get full effects (or any for that matter) and may be getting carcinogens from the butane that she does not need!!! I have no idea where he got this idea to mix these two with no other steps, all of my research shows in depth processes. He tells me to stop questioning him, I just need some advice for myself and him as well!! Is this mixture good? If not, what can we do to salvage the shatter?
