The Laughing Squid posts these pictures made by Rusty Blazenhoff and Ken Dashner, along with a little information they found on Wiley Online Library:

The Dangerous Drugs—Identification Kit contains harmless facsimiles of the more commonly abused dangerous drugs. The Kit was designed to be used primarily as an instructional aid in educational and training programs directed toward combating the existing narcotics and dangerous drugs problem. It consists of a plastic container which is transparent and durable. Plainly visible within the container are facsimiles of amphetamines and barbituates, reproduced with exacting fidelity in terms of color, size, shape, and other distinguising characteristics.
