Ecstasy has been the drug of choice among many clubbers for more than a decade. They think
it’s fun, they think it’s safe, but now there’s worrying new evidence that the ecstasy craze may have
created an entire generation of people that are more vulnerable to brain disorders. New research shows
that ecstasy damaged brain cells that are important for movement, so-called dopamine receptors. A study
was done by examining monkeys’ brain activities after giving the dance drug ecstasy. Monkeys were
given a dosage of three tablets over nine hours. A normal brain is full of dopamine, but after the animals
were given ecstasy, most of the dopamine receptors stopped working. It can damage brain dopamine
neurons and may render the user more susceptible to developing Parkinsonism as they grow older.
