Pill testing is a process used to identify substances contained within a pill, usually illicit substances.

Reagent testing kits[edit]

A test is done by taking a small scraping from a pill and placing it in the reagent testing liquid.[1] The liquid will change colour when reacting with different chemicals to indicate the presence of certain substances. Testing with a reagent kit does not indicate the pill is safe. While the testing process does show some particular substances are present, it may not show a harmful substance unaccounted for by the testing process. Testing kits are distributed on a not-for-profit basis by Dancesafe and commercially.

[citation needed] It is advised to check the references for photos of reaction results.[2]

Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive.[3]
