Is the Controlled Substances Act really responsible for the general decline since 1970? We’re not sure, but what is clear is that drugs are foundational technologies, like the motor, combustion engine, semiconductor, or the concept of an experiment. New drugs lead to scientific revolutions. Some of those drugs, like coffee, continue to fuel fields like mathematics and computer science, even some hundreds of years later. With apologies to Newton, “If I seem higher than other men, it is because I am standing on the shoulders of giants.”
