Ecstasy increases blood pressure
and pulse rate, and raises body
temperature. The user loses appetite
and sweats a lot, maybe even vomits.
Some people can overheat, while
side effects such as involuntary
jaw clenching, teeth grinding and
dilated pupils are common, as is
anxiety and insomnia during the
comedown. Taking a pill in a hot,
humid environment (like a rave party
or a mosh pit) can cause dehydration,
and although rare, heart failure and
death. There’s also well-known cases
of people over-hydrating and suffering
water-intoxication, leading to a
swelling of the brain.
