PARENTS across the UK are being urged to talk to their children about the risks of drug use.

It comes as it’s revealed children are using the dark web to sell potentially lethal ecstasy pills.

Exeter Police said its neighbourhood team was “concerned” that children are using a blue drug called “Darth Vader” - shaped like the Star Wars villain - bought on the dark web with fatal consequences.

The force added: “Please ensure you know where your child is and teach them about the risks of drug use.”

Last year, a 14-year-old boy suffered kidney failure after taking half a pill.

Three teens and an adult have died in the space of a month in the south west of England after taking suspected ecstasy pills.
