Super-strong pills containing three times the normal dose of MDMA are circulating New Zealand - and it's sparked a warning before New Year's Eve.
KnowYourStuffNZ has identified several pills during its testing, saying they're likely to be found around the country over the holiday period.
"A common dose of MDMA is around 80-120 milligrams, depending upon a user's body weight. These pills contain up to three doses in a single pill," a post on the KnowYourStuffNZ website says.
"These pills should be approached with caution. Users are advised that the only way to guarantee safety is to not take them. For those who do choose to take them, our recommendation is to only take a third of a pill at most, and wait at least an hour before considering taking any more."
Taking too much MDMA can result in a very unpleasant experience, health risks, and sometimes even death.
"If you or someone you know has taken one of these pills and experiences dizziness and vomiting, a sharp rise in body temperature, muscle cramping, heart palpitations, seizures, or unconsciousness, seek medical attention immediately," KnowYourStuffNZ says.
These suspected high dose pills include:
