Cocaine

Cocaine was an illegal drug in the United Kingdom. Baz Bailey decided to start selling it in the Coal Hill School area. To prevent this, Samantha Jones reported him to the police, but they found no evidence of the substance. To prevent Sam from repeating this, Baz planned to force the drug upon her so that she became addicted. However, the Eighth Doctor prevented this and took the drugs. The police arrived upon the scene and arrested the Doctor for possession of an illegal substance. (EDA: The Eight Doctors)
