Drug addict

A drug addict is someone who is addicted to drugs. This could range from everything including cocaine to heroin to methamphetamines and beyond. Drug addiction features prominently in films of the crime drama genre, but may also appear in other genres as well. As is often the case, drug addiction will have averse effects on an individual's physical and mental health and may even lead to death. To say nothing of what it does to an addict's family. Kids... be smart. Don't do drugs!

Nightmare on Elm Street 3: Dream Warriors, A
In A Nightmare on Elm Street 3: Dream Warriors, the character of Taryn White was a drug addict. It is unspecified which was her drug of choice, but as pointed out by an orderly named Lorenzo, she had track marks along her arms, suggesting an addiction to heroin. By her own account though, those marks were "ancient history", implying that she was attempting to clean herself up.
