It was "Dead Flowers." About guy who travels in time by temporarily jumping into other people's bodies. The problem is that he's a heroin addict, so he leaves a trail of junkies behind as he jumps from one to the next. The government agency he works for doesn't care, but the woman assigned to look after his body does and finally decides to kill him.
Any connection to "Quatum Leap" the TV show? Main character goes body hopping through time and has to solve other's problems.
