Death Drug is a 1978 American exploitation film directed by Oscar Williams[1] that deals with the harsh and deadly effects of PCP, or "angel dust".
The film starred Philip Michael Thomas as a plumber turned musical artist who got hooked on angel dust, leading to a drastic change in personality and, soon, his demise.
The film begins with a news anchor reporting on a crazy man, suspected to be high on angel dust, attacking a group of roller skaters at a park in Venice, California; the man was apprehended by police and handcuffed, but broke free of the handcuffs and escaped, only to get hit by an automobile and die of his injuries.
Convinced of the magic cigarette's powers, he became hooked on angel dust, making regular visits with his drug dealer to get more of the stuff.
Scared and mentally tormented, Jesse leaves the store through the back onto a street, running towards a moving delivery truck, thinking that it was alive.
