Pill testing

From Wikipedia, the free encyclopedia

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

Since illicit drugs like MDMA are bought from drug dealers on the black market, both the source and contents of the substance are unknown. Pills sold by dealers as Ecstasy, may not contain the desired substance, usually being MDMA. Testing the pill can show if substances, such as MDMA, are present.

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.

DanceSafe reagent testing kits are Marquis, Mecke, and Simon's, and EZ Test kits are Ehrlich, Mandelin, Marquis, Mecke, and Scott. The EZ Test table here is a general guideline of the reactions from each substance and testing kit instructions may indicate different results. Reactions may show different colours if more than one substance is present. By using a series of these reagents, one can determine by the process of elimination what substance the pill contains. For example, marquis turns black in the presence of MDMA, and a common misconception is that if the marquis goes black, you have MDMA. But it can also turn black in the presence of MDA, MDEA or other less common MDXX-series analogs so usually a series of these tests are done to further determine contents.

Online testing kits are used by individuals to post reports to TranceSafe and the Pill Reports websites. At nightclubs and rave events organisations such as Enlighten Harm Reduction in Australia, Dancesafe in the United States and the Green Party Drugs Group in the United Kingdom conduct on-site pill testing.

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


EcstasyData.org is an independent laboratory pill testing program operated and primarily funded by Erowid with some funding support by Dancesafe. Testing is done using a GC/MS, which can positively identify substances where reagent tests can only give a clue what chemical can be found. When a pill contains more than one active compound, reagent tests are often misleading or not conclusive. Substances identified are listed on their website. Substances sent in to the lab are destroyed in the testing process or destroyed following DEA guidelines.


Pill testing is controversial because it can give the user the false impression that a pill is "safe." The act of pill testing may be illegal in many countries because it requires the tester to come into contact with the illicit substance, and so can then be charged with possession of an illicit substance. Many states in the United States deem the testing kits "drug paraphernalia," and possession and sales could result in a misdemeanor. DanceSafe and other organizations also test pills at raves, festivals, and other gatherings. Onsite pill-testing services have raised concerns as pills are not destroyed in the testing process, and are returned to the drug user after testing.
