Most scientific studies are not allowed to do experiments with human beings. That was the case in concentration camps, but you can't really allow that. A lot of our knowledge stems from informal accounts, from people who use heroin. Now, in the later years we've had heroin trials in which heroin was prescribed in a legal setting to people, and that changed the whole access to that kind of knowledge, because you would also ask people were inside the heroin trials how they felt, what it did to them, and so on, and that has provided researchers with new knowledge.
