Ecstasy pills are usually swallowed, although some people crush them up and snort them. The amount of MDMA in ecstasy pills varies massively. Some pills sold as ecstasy actually contain other, more dangerous, drugs that take longer to kick in.
For this reason, you should never take a whole pill in one go, even if you’ve taken ecstasy before.
Drinking too much (including water) can also be dangerous. Users should sip no more than a pint of water or non-alcoholic drink every hour.
