Illegal markets resulting from drug prohibition create multiple problems:

- Fuels criminal enterprises and underground economies
- Makes drug use more dangerous due to lack of quality control and safety standards
- Forces users into risky situations to obtain substances

The better approach would be:
1. Create a heavily regulated legal market for certain substances
2. Maintain bans on the most lethal/dangerous drugs
3. Allow controlled use of psychedelics in appropriate therapeutic/medical settings with proper oversight

This would help eliminate black markets while providing safer access through legitimate channels, similar to how alcohol and tobacco are currently regulated.
