What is posh drug wise

In drug terms, Posh is the nickname for cocaine. It's been called this due to the high price of the drug, and the fact that the well-to-do, "posh" class of people, are the most likely to be able to afford and use it. Cocaine is a strongly addictive stimulant drug which can cause death when abused.
