I Have a close friend who is dieing of cancer, She has never smoked before and has asked for some releaf via marijuana, She asked me about cooking oil/butter. She is on a limited budget So i want to make the weed go as far as it will and still do an effective job at making her comfortable. We will be starting out with an oz but i need to know what is the most effective way to use it? Butter? Oil? make is super consecrated then cut it with regular oil or butter? Just need some advise.
