Although very rarely reported, opioids may also be found in tablets buy mdma sold as MDMA. In the period from 2019 to 2023, caffeine, 4-CMC (4), amphetamine, cocaine and MDA were the adulterants most commonly found in MDMA samples (tablets and powders/crystals) submitted to drug-checking organisations belonging to the TEDI network. Again, these data should be interpreted with caution and not necessarily be seen as statistically representative of the market as a whole. Crystal MDMA appeared on the European market at that time, as a response to a fall in consumer confidence due to concerns about the low quality of ecstasy. However, adulteration is commonplace, and therefore these tablets may contain a variety of substances in addition to, or instead of, MDMA. Retail quantities sold online are often dispatched in post and parcels from EU Member States to consumer markets in Europe and globally, and cryptocurrencies are often used to settle these online transactions.

While a slight decrease in price was observed in 2022 for ecstasy tablets, this may not be statistically significant or sustained in the coming years. In fact, it could be argued that MDMA in the form of ecstasy tablets became cheaper between 2012 and 2019 as tablets containing larger quantities of MDMA became increasingly available on the market (see Section The trend of large tablets containing more MDMA may be reversing). For countries reporting data in 2022, a considerable retail price range was observed, with prices per ecstasy tablet ranging from EUR 4 to EUR 19 (mean) and prices of MDMA powder from EUR 6 to EUR 50 per gram. Occasionally, tablets containing 250 milligrams or more of MDMA are encountered on EU drug markets. This trend may be a combination of the scheduling of PMK glycidate, and a reduction in demand for MDMA during the COVID-19 pandemic, and is in line with the changes observed in the adulteration of ecstasy tablets (see Section Ecstasy adulteration is responsive to market pressures). This means that the ratio of MDMA to fillers (excipients) in the mixtures used to make ecstasy tablets did not increase over this time period.


Estimates from darknet market studies in 2015 suggested that MDMA was the third most popular drug (after cannabis and pharmaceuticals) purchased on the darknet, accounting for 25% of drug sales. MDMA has also developed a substantial niche in online darknet markets accessed via dedicated TOR browsers and paid for using cryptocurrencies like Bitcoin. The addiction risk ties back to its effects on neurotransmitters. MDMA, due to its psychoactive effects and potential for misuse, is a substance often tested for in various drug screening processes. When sold in pill form, two pills with the same logo or symbol may have different effects — they can come from different sources and have different ingredient

The drug can be used to reduce inhibitions and eliminate anxiety and produces feelings of empathy for others. In Napa County MDMA or ecstasy is sold in pill form. Persistent deficits in serotonin are likely responsible buy mdma for many of the persistent behavioral effects that the user experiences. MDMA in its true form works in the brain by increasing the activity levels of at least three neuro-transmitters, serotonin, dopamine, and norepinephrine.
Ecstasy adulteration is responsive to market pressures


A study conducted by 10 drug-checking organisations from the TEDI network found that the increase in MDMA content in tablets in this time period was directly related to an increase in the average weight of ecstasy tablets (Vrolijk et al., 2022). The average content of MDMA in ecstasy tablets appears to be on a slight downward trend from 2019, after close to a decade of increasingly stronger (and larger) tablets becoming available on the market. On occasion, neurotoxic compounds such as PMMA (5) are detected mixed with, or as a replacement for, MDMA in ecstasy tablets. From 2019 onwards a new cycle appears to have begun, whereby the number of ecstasy tablets containing other substances alongside, or instead of, MDMA has increased (as expressed by a drop in percentage in the indexed trends shown above from 96 % in 2019 to 73 % in 2022). Crystal MDMA was marketed as a purer product compared to ecstasy tablets, an assertion that was and remains largely true (see Section The trend of large tablets containing more MDMA may be reversing). One way to observe these cycles is to monitor rates of adulteration, as expressed by the percentage of tested samples of seized ecstasy tablets that contain MDMA and no other buy mdma scheduled substances.
Wastewater-based methods
Although often used interchangeably, ecstasy and MDMA are not necessarily synonyms. Additionally, particularly with instant messaging applications, transactions may be organised online, but completed using in-person pick-up or ‘dead-drop’ delivery. This appears to be supported by existing studies that indicate that MDMA is bought online mostly by retail distributors for the purpose of re-sale rather than purchased directly by retail clients (Aldridge and Décary-Hétu, 2016; Gremeaux, 2022). Data collected from individuals submitting MDMA samples to drug-checking services between 2019 and 2022 appear to support these findings from the EWSD.
