Tolerance (need to increase the dose to feel the same effect)
Tolerance to MDMA appears to develop quickly. That said, with repeated use, it becomes difficult, if not impossible for users to experience the same effects they did when they first started.
Although some users become dependent, very few cases of MDMA-specific dependence have been reported in the literature. Since most users take this drug only occasionally, dependence is not very prominent.
Withdrawal symptoms are caused by a depletion of serotonin and may include depression and anxiety. Other symptoms associated with withdrawal are insomnia, panic attacks, agitation, psychosis and paranoid delusions. During withdrawal, users may also experience fatigue, sadness, bad moods and nightmares.
