(卤)3,4-Methylenedioxymethamphetamine (MDMA, Ecstasy) is a synthetic ring-substituted amphetamine analog that produces a unique blend of stimulant and psychedelic effects. Considerable research demonstrates that
MDMA stimulates the release of neurotransmitters, such as serotonin and norepinephrine, from brain neurons producing a high that lasts from 3 to 6 hours, but the length of a high is variable based on the user. The drug's rewarding effects vary with the individual taking it, the dose taken,...

Effects of MDMA on the Human Nervous System 3Conclusions MDMAis a ring-substitutedamphetamineanalog with reinforcing psychoactive effects, in addition to neurotoxic potential toward central 5-HT neurons. Its major pharmacological effects appear to be secondary to actions at brain monoaminergic neurons, ...

Ecstasy is a Schedule I substance under the Controlled Substances Act, which means that the DEA has determined that it has no medical benefit and a high potential for abuse.Its primary effects are in the brain on neurons that use the chemical serotonin to communicate with other neurons. The ...
s team from MedUni Vienna’s Center for Physiology and Pharmacology show, the new chemical compounds have a similar effect to MDMA on the relevant clinical target structures in the brain (such asserotonin,dopamine, and noradrenaline transporters), which are crucial for regulating mood and emotion....
MDMA boosts the brain’s production of feel-good neurotransmitters, causing a burst of euphoria and good will toward others. But the drug can also cause high blood pressure, memory problems, anxiety, irritability, and confusion. And repeated use can cause lasting changes in the brain. If the...
Although MDMA affects the brain in the same ways no matter how it is taken, the delivery method can affect both the dose and how quickly the drug is absorbed by the body. Powder carries the risk of less consistent dosing, and snorting or dabbing can cause a faster-acting, though shorter...
