Drug stereotypes in TV and film

[Pondlife]

What are your favourite drug stereotypes on the TV and in films?

Here are my two favourites, both from memories of 1970's American cop shows like Starskey & Hutch and Hawaii Five-O, and British police series like The Sweeney:

1. Heroin is always injected in a hotel room with a flashing neon sign outside the window, and the syringe must be one of those old style glass ones that has to be assembled like a sniper rifle.

2. When a policeman finds suspected drugs, he will always dip his finger in the powder and taste it before giving a knowing nod and cuffing the suspect (even as a child I realised it was pretty stupid to taste some random unidentified powder).
