The Dangerous Drugs (Supply to Addicts) Regulations 1968[1] determined the consultants who could prescribe, or treat addicts either in psychiatric hospitals or drug dependency units.

Other medical staff, if supervised by the consultants within the hospitals, would also be able to obtain licences.

Doctors working outside the NHS would be considered if their organisations had similar facilities to the DDUs.

[2] Doctors who disobeyed these regulations might have their permissions to supply rescinded.
