Stephen Freye has been jailed for life at Cardiff Crown Court after mowing down an innocent passer by.
The court heard the 22-year-old snorted 70 lines of cocaine before climbing into his car and looking for a victim to run over late at night.
Kyle Griffith, 25, was on the way home from work when Freye aimed his car at him - killing him instantly.
Freye claimed he was hallucinating after sniffing a bag of 10 grammes of cocaine over a weekend.
Cardiff Crown court heard Freye confessed to police at the scene: "I was told to kill a stranger." Freye, of Roath, Cardiff, denied murder but was found guilty following a two week trial.
