Pot belge

[1][2] The term is commonly used to describe a mixture of drugs, variously constituted from cocaine, heroin, caffeine, amphetamines, and other analgesics.

[3] A French reference also lists morphine in the mix, and notes that it can also be called "insane person mix",[4] though it's unclear whether this refers to the potential results of its use, or the suggestion that "you have to be crazy to take it."

The mixture has become widely associated with the world of professional cycling where it was used for many years, before the institution of highly regulated testing.

[5] There are suggestions that its use among amateur participants has been on the increase as both a recreational and a (relatively cheap) performance-enhancing drug.

[6] In his memoir 'Prisonnier du dopage', former pro cyclist Philippe Gaumont describes using pot belge for winter training purposes more than as aid during competition: "J'ai toujours entendu les anciens dire que prendre les amphétamines pour une grande sortie d'entraînement aide à 'débloquer le moteur'" (rough translation from French: "I've always heard old timers say that taking amphetamines before a training ride helps to 'unclog the motor'").
