The kit aims to allow users to test the purity of the illegal drug.

It works by mixing a scraping of a tablet with a special liquid and testing the result against a swatch of seven different colours to identify the contents, the inventors claim.





Kit tests purity of drugs

"It's something we ought to stop before it starts," he told BBC Radio 4's Today programme.

"I think it's immoral, just a money-making venture going on the back of the trend in young people taking drugs."





Drugs czar Keith Hellawell: "An immoral, money-making venture"

The test itself was "extremely crude" he said. It identified a number of substances that may be in a tablet, but did not pick out what else may be in it.

Even a pure ecstasy tablet was life-threatening to many people, he said.

"Therefore, it [the kit] is building false confidence. It's immoral and just a crude measure for money-making."

Ecstasy damaged all parts of the system, and people were getting involved with other drugs, as they took them to counteract the effects of ecstasy, Mr Hellawell said.

The number of people using ecstasy had begun to drop, he said, adding: "My worry is that this sort of thing [the kit] may encourage other people to take it."





Tony Puglio believes the kit will help users

Information from the kit will allow drug users to make informed decisions before they take ecstasy, he claims.

He told BBC One O'Clock News: "All drugs carry risks and we assume that people who use the kit will already be taking those drugs.

"Because ecstasy manufacture is unmonitored there are a variety of drugs inside the pills and all of those have different mental and emotional affects.

"What the kit does is to assist you what substance is in the pill and gives you some information on the effects."
