Hello. I'm a french nurse with 20 years experience currently working in Norway. I work in elderly care as a night shift. But, why I'm here now is because after watching Youtube videos about the homeless in USA (Invisible people, AML, etc.) I have questions about doses these people put in themselves. They say they need 7 to 12 "bags" a day, so what's in a "bag" anyway and how much of drugs is it?
