In any case, there really isn't much that governments can do about this problem. If people decide to do harm to themselves in any manner whatsoever, we cannot force them to accept help. Just as we can't stop individuals from drinking a bottle of booze every day or smoking a pack or two of cigarettes each day - other than to make these habits much more expensive for the consumers of these things-  we can't stop people from taking fentanyl, heroin, or anything else.
