The human body manufactures its own painkillers to ensure survival when injured. This program shows how opium and its derivatives, heroin and morphine, hijack that natural pain-numbing ability. Illustrating the brain's ability to alter its own chemistry when attacked by drugs, the program depicts the process by which brain receptors become desensitized and thus addicted. Tranquilizers - and the potentially lifelong physical dependency and psychological problems they can cause - are also studied.

Like an avenue filled with neon signs, the brain's so-called pleasure pathway can light up or go dark, depending on what sort of stimulation it receives. This program explores the workings of the human nerve center under the influence of cocaine, amphetamines, and other stimulants, and shows how our understanding of brain disorders and drug addiction has increased by studying these drugs.
