The half-life of MDMA is about 8 hours, which means that it takes about 8 hours for half of the drug to be eliminated from your body. This means that if you take 100 milligrams of MDMA, after 8 hours, there will be 50 milligrams left in your system. Ecstasy, also known as MDMA, is a drug that is often used at nightclubs and raves. However, ecstasy can also have negative side effects, such as dehydration, overheating, and anxiety.

In the United Kingdom, MDMA was made illegal in 1977 by a modification order to the existing Misuse of Drugs Act 1971. Although MDMA was not named explicitly in this legislation, the order extended the definition of Class A drugs to include various ring-substituted phenethylamines.200201 The drug is therefore illegal to sell, buy, or possess without a licence in the UK. Penalties include a maximum of seven years and/or unlimited fine for possession; life and/or unlimited fine for production or trafficking.
Other Drug Detection Times
MDMA, or 3,4-methylenedioxymethamphetamine, is a synthetic amphetamine derivative known as a recreational drug since the 1980s by street names like “Ecstasy,” “Molly,” and “XTC.” The entactogenic properties foster euphoria, memory retrieval, and enhanced sensory perception. This course sheds light on clinical aspects of MDMA use, emphasizing its potential life-threatening impact on cardiovascular, neurological, renal, and hepatic systems. Certainly, the most controversial aspect of MDMA pharmacology is its potential to induce neurotoxicity. The neurotoxic effects of MDMA have been extensively reviewed by others,165,166,167,168,169,170,171 and thus, we will focus only on the key studies. Additionally, we will attempt to highlight why this is such a contentious area and why the controversy is not likely to be resolved soon.

In Australia, MDMA was rescheduled on 1 July 2023 as a schedule 8 substance (available on prescription) when used in the treatment of PTSD, while remaining a schedule 9 substance (prohibited) for all other uses. Permits for research uses on humans must be approved by a recognized ethics committee on human research. Pharmacokinetic parameters for mephedrone 200 mg and MDMA 100 mg are summarized in Table 2. Figure 2 represents plasma concentration over time curves of mephedrone and MDMA, including the metabolites of MDMA (HMMA, MDA, and HMA). Mephedrone plasma concentrations were determined by gas chromatography-mass spectrometry. The method consisted of a liquid-liquid extraction with tert-butyl methyl ether and a further derivatization with N-Methyl-N-(trimethylsilyl) trifluoroacetamide (MSTFA) of mephedrone.
MDMA (“molly” or “ecstasy”) is a club drug with stimulant and hallucinogenic effects. The primary effects of molly may last for up to six hours, but the drug remains in the body and can be detected by drug tests for a much longer period of time. In conclusion, mephedrone presents an abuse potential profile similar to MDMA, but with some differences, a more rapid onset and a shorter duration of effects, probably related to its brief elimination half-life. Such differences could explain, in real life conditions, a more compulsive pattern of use to prolong the duration of the desired effects and, consequently, an increased risk of toxicity. Our study has some limitations, the relatively scarce number of participants could justify a lack of power in the comparisons between both active drugs. Although the study was designed to explore the abuse liability of mephedrone in comparison with MDMA, the protocol only included one dose of mephedrone, and we cannot extrapolate our results to higher narcissism and alcoholism doses or demonstrate a dose–response relationship.
- The study used a highly controlled hospital setting and included only healthy volunteers.
- In general, the unlicensed use, sale or manufacture of MDMA are all criminal offences.
- People who are heavier tend to have a slower metabolism, which takes them longer to eliminate drugs from their system.
- MDMA metabolites are substances that are produced when MDMA is broken down by the body.
Is the stereoisomer R-MDMA a safer version of MDMA?
- Note that taking any additional supplements and substances may create dangerous interactions.
- MDMA appears to be less addictive than some other substances, such as cocaine.
- Scientists continue to research effective treatment options for withdrawal from Molly, but there are currently no specific treatments for it.
- Therefore, the present study compared acute responses to racemic MDMA, S-MDMA, R-MDMA, and placebo in a double-blind, crossover study in healthy participants.
- The 2 most frequently reported causes of death include hyperthermia and hyponatremia.
- Generally, opioids can be detectable in urine for around 2 to 4 days after use, but some opioids with longer half-lives can be detected for a longer period.
Such effects are similar to those spontaneously reported by mephedrone recreational users and are the basis of its potential abuse. In addition, we described for first time in a controlled study, the pharmacokinetic parameters of mephedrone after a single oral dose. Evidence from animal studies and human reports indicates that both enantiomers of MDMA are active and produce differential effects or are even reportedly needed to synergistically produce the full MDMA experience 13, 16, 17.
However, we found similar minimal increases in body temperature after S-MDMA and R-MDMA in the present human study. An effective dosing paradigm was established by Oehen and co-workers utilizing low dose MDMA as an active placebo.221 The use of an active placebo is an important part of the experimental design implemented by Oehen and co-workers. Inactive placebos, such as lactose, fail to produce physiological and psychological responses noticeable to trained clinicians or experienced MDMA users. This raises the question as to whether or not studies utilizing inactive placebos can truly be considered double-blind experiments. Patients in the experimental treatment group received an initial dose of 125 mg of MDMA followed by an additional 62.5 mg after 2.5 h. The active placebo group received an initial dose of 25 mg of MDMA followed by an additional 12.5 mg 2.5 h later.
