trail mix
n.— «Coming out of all of this is what is called “Trail Mix” where upwards of five to six different compounds are mixed into one tablet which is being sold as ecstasy. “Caffeine, codeine, ketamine, GHB, meth, viagra—just about anything is mixed into them. And when they overdose, paramedics have no idea what they took and that causes more problems into trying to revive them.”» —“Chemical drugs the latest trend” Central Peace Signal (Rycroft, Alberta, Canada) Mar. 14, 2006.
