How does MDMA affect the brain?
How does MDMA affect the brain?
Dopamine—produces increased energy/activity and acts in the reward system to reinforce behaviors
Norepinephrine—increases heart rate and blood pressure, which are particularly risky for people with heart and blood vessel problems
Serotonin—affects mood, appetite, sleep, and other functions. It also triggers hormones that affect sexual arousal and trust. The release of large amounts of serotonin likely causes the emotional closeness, elevated mood, and empathy felt by those who use MDMA.
Other health effects include:
nausea
muscle cramping
involuntary teeth clenching
blurred vision
chills
sweating
MDMA’s effects last about 3 to 6 hours, although many users take a second dose as the effects of the first dose begin to fade. Over the course of the week following moderate use of the drug, a person may experience:
irritability
impulsiveness and aggression
depression
sleep problems
anxiety
memory and attention problems
decreased appetite
decreased interest in and pleasure from sex
It’s possible that some of these effects may be due to the combined use of MDMA with other drugs, especially marijuana.
What are other health effects of MDMA?
High doses of MDMA can affect the body’s ability to regulate temperature. This can lead to a spike in body temperature that can occasionally result in liver, kidney, or heart failure or even death.
In addition, because MDMA can promote trust and closeness, its use—especially combined with sildenafil (Viagra®)—may encourage unsafe sexual behavior. This increases people’s risk of contracting or transmitting HIV/AIDS or hepatitis.
