West Yorkshire Police have been forced to issue a warning to attendees heading to Leeds Festival about the dangers of “super-strength” MDMA.

According to The Loop, a none profit company that triumphs and provides safe drug testing at festivals, there have been reports of drug dealers selling a substance called ‘N-ethyl Pentylone’, a drug which has been described as “fake MDMA”.

The dangers, according to The Loop and West Yorkshire Police, is that ‘N-ethyl Pentylone’ is considered to be around three or four times stronger than normal MDMA. Furthermore, the substance is exactly the same in appearance and is normally sold it crystal, pill and powder form.

While the high from the drug doesn’t last as long as MDMA, the Yorkshire Evening Post claim that the side effects are much more severe and can “lead to 12 to 48 hours of severe insomnia, paranoia, erratic behaviour and drug-induced psychosis.”

Reacting to the news that ‘N-ethyl Pentylone’ may be sold at Leeds Festival this weekend, West Yorkshire Police said: “Whether it’s claimed to be a legal high or a banned substance, people supplying drugs are more often than not unscrupulous individuals who don’t care about you,” in a statement.

“Aside from the potential effect that anything you take may have on your health and wellbeing, drugs can also have a significant effect on your life and future. A conviction for taking or supplying controlled drugs to your friends will impact on your life. This can include travel plans, employment prospects as well as your general reputation.”

They concluded: “Come to the festival and enjoy it but don’t let one bad decision ruin the weekend and jeopardise your future.”
