I need help, please
In the late 1970's, a graduate student at a major West Coast university began synthesizing new classes of drugs and testing them on himself. After being expelled from the university, he began making his living by illegally synthesizing and selling to heroin addicts compound B, a synthetic analog of meperidine (Demerol). After shortening his synthetic procedure and self-injecting his product, he developed severe symptoms of Parkinson's disease, as did several of his young clients, one person...
