UK police issue warnings over potentially lethal Donald Trump MDMA pills

UK police are issuing warnings over potentially deadly ecstasy pills shaped like Donald Trump.

The pills, circulating around the Leeds Festival, contain as much as 260mg of MDMA each. Even more potent shapes have been tested at 330mg per pill.

"These are very dangerous, high strength pills, up to three times the normal average adult dose," the Leeds Festival police tweeted.

A 17-year-old girl died at Leeds Festival in a suspected drug overdose early on Saturday morning (local time). A 17-year-old male has been arrested on suspicion of supplying controlled drugs.

“While the exact cause of her death is yet to be established, the information we have indicates that she has taken a combination of drugs," police commander Supt Matt Davison said.

"This is a tragic incident and I hope serves as a timely reminder to others of the risk of taking illegal substances, particularly when mixing different types of drugs and drinking alcohol."

Drug harm reduction nonprofit The Loop has issued an alert for other Trump pills, which it says contain over three times the common dose.

"Donald Trump pills causing serious medical problems across the UK this weekend," it tweeted.

"Already associated with hospital admissions across the UK. Take care and seek medical help if unwell."
