The Marquis Reagent is a drip test to determine the contents of certain drug substances. This reagent test determines the presence, however not the quality or purity, or certain drugs. For example, if someone wanted to test what they thought was MDMA, they would use the Marquis Reagent and it would quickly turn black or purple.

It is also primarily used for testing ecstasy and other opiates such as codeine, heroin, etc. The test is a mixture of concentrated sulfuric acid and formaldehyde. Additionally, to use the test, there are many steps that need to be followed.

First, it is essential that one reagent kit is being used one at a time. If multiple kits are switched, it is possible they could be ruined. As this reagent is a chemical, wear latex gloves as it could be toxic to skin, mouth, and eyes.

Next, take a bit of the substance in question and put it on a plate. Then, take the Marquis Reagent and squeeze one drop onto the substance. Be careful to not let the actual bottle touch the substance, as this will ruin any further tests.

Finally, observe the color change immediately and use the chart supplied to evaluate the results.

Eduard Marquis, a Russian pharmacologist, invented this test in 1896. It was first tested at University of Dorpat and now is widely used as a basic spot test. History reveals that drug checking has been involved in nightlife and music scenes of many European countries since the 1990s. This emergence of raves and dance-music culture also affected Australia in the 1970-80s. During this time, “party-drugs” like psychoactive substances became very popular. Drug checking and regent test soon followed as a harm reduction strategy. In the 21st century, a very similar use is applied. The Marquis Reagent test was particularly popular since it reacts with many drugs used in the dance scene. Music festivals like Coachella have a history for being a place where many people sell and use drugs. With the prevalence of people selling fake drugs and the recipients not knowing the true contents of their substances, using reagent test became popular. One study by the concluded that 76% of people thought that they had unknowingly consumed fentanyl. Of the same sample, the majority concluded that they wanted to know the presence and amount of fentanyl in their drugs as well as any other substances present. This awareness of contamination in drugs can overall reduce the chance of overdose and create well-informed, responsible users of drugs. While there is no “safe” way to use drugs, the promotion of education around the issue can help save lives, or at least prolong them. 

Furthermore, as the years progress, and the youth of our country become increasingly dependent on drugs at younger ages, more evidence is revealed that various forms of drug testing is overall beneficial. Among youth, ages 12-18, the demand for MDMA has increased, approximately 2.8 million having at least tried this drug. The Loop, a nonprofit organization community interest company provides drug testing and harm reduction services. They set up at a festival for four days and analyzed 247 substances submitted by the public. The results shown were shocking. Half of the drugs submitted were smuggled into the festival. 48.3% of the substances were acquired on the fairgrounds. Just about 1 in 5 samples were different than what they were advertised or sold as. Drugs that were obtained on the grounds of the festival were more than twice as likely to be miss sold as a different substance. In many cases, cheaper drugs were sold as more expensive substances. A majority of people ended up throwing away the adulterated substances. Overall, drug testing leads to a more open dialogue about taking drugs and can lead people to buy drugs from different dealers which could result in safer consumption. 

Moreover, many organizations have taken strides to combat the misinformation and dangerous use around drugs. Dance Safe is an organization that continues to fight for harm reduction and education around substances. The founder, Emanuel Sferios established the organization in the San Francisco Bay Area in 1998. Now, they are a national organization with chapters all along North America. They are commonly known for bringing pill and drug tests to raves and nightlife communities. Additionally, this organization created the sole publicly acceptable laboratory analysis program for ecstasy in North America. Another similar organization founded in 2014 is Unharm. The organization began when Will Tregoning became frustrated with the ways in which the War on Drugs has failed. A journalist, Lisa Pryor wrote about these issues in her 2011 book. Soon after, Will and Lisa sparked up conversation and developed Unharm. They then brought this idea to an entrepreneur with an extensive involvement in drug policy. They are a grassroots organization striving to make drug use positive and safe that argues that drugs shouldn’t be illegal, as this is a counterproductive measure. This organization strives to change laws and policies that could promote the wellbeing and safety around drugs. 

The Marquis reagent test and other drug/pill testers are used to test the actual substance within acquired substances. From the 1800s to 2019, this reagent test is used to serve as a harm reduction or a safer alternative to blindly taking and buying drugs. With the emergence and increase of popularity behind “party-drugs,” such as ecstasy tests like Marquis couldn’t be more significant. Cases like Alex Ross-King illustrate this point clearly. Alex, after already “pre-loading” on the bus ride there, was reportedly afraid of being caught having drugs by festival security and she subsequently took 2 MDMA pills at once. Just 9 hours later, she way pronounced dead by overdose after many attempts at saving her. Her case is devastating but unfortunately not unique. There are many instances like this every year. However, with the increased use of the Marquis Reagent, instances like these can become less frequent. Fewer teenagers will die because of drug use and misinformation. Overdosing on MDMA is pretty rare. It is possible that the overdose was due to physical exertion and the effect of alcohol as well but it also could be because of other substances being present in the drug she was taking. Opening the dialogue about drugs towards a narrative that promotes harm reduction and drug testing like reagents can save the youth of our country and lead us down a greater, more understanding path.
