Absolutely (such as an ongoing trial project in Vancouver, Canada), but it’s not currently not politically realistic in many regions.

In the meantime for the individual, I believe it’s best to sit down and talk to a young person about the risks of drugs in a realistic way. Not the DARE fearmongering stuff, but talking about how drugs can be an easy distraction and source of drama from the things in life that should be higher priorities (e.g. relationships and career). This should also include specific advice about avoiding pills because of fentanyl tainting.
