Bumquist
Dr. L Ron Bumquist is an "expert" on drug abuse called in to the convention in the Flamingo Hotel. He describes "drug addicts" in a very extremist, and exaggerated tone similar to how many politically-motivated scientists still do even today. He claims that the reefer butt looks like a cockroach and that's why it is called a roach clip, a statement that makes Dr. Gonzo exclaim that you'd have to be crazy on acid to think that.
