Tolerance & dependence

Tolerance

People can develop tolerance to the pleasurable effects of ecstasy. This means that more ecstasy is needed to get the same effects as before.

Dependence

A substantial minority of those who use ecstasy regularly are likely, at some point, to become psychologically dependent ecstasy and will experience chronic problems in relation to their use of ecstasy.

Research into the long-term risks of ecstasy use has so far shown no conclusive evidence that people become physically dependent on ecstasy.
