I saw this movie over twenty years ago, back when CBS showed late night movies instead of Letterman et al. I thought it was the worst, most poorly produced and thought-out movie ever. Nothing I have seen since has caused me to change my mind. It does not even fall into the "so bad it's good" category. My roommate and I were ridiculing almost every aspect of this disaster.
One example: the drug at issue, "Blue Sunshine," supposedly made the victim's hair fall out. The "falling out" consisted of the victim's entire head of hair coming off, all at once, in one piece -- obviously a wig being pulled off. The movie did not so much come to a logical end as, suddenly, the camera pulls back and announces that the movie is over.
I remember that the closing credits announced that the film had been produced by "The Blue Sunshine Corporation," leading me to suspect that it was a tax loss project designed to be bad, a la the plot of The Producers. If so, it succeeded.
