Professor Sue Pryce has warned of the dangers of drug taking being seen as normal.
Following a night out in Manchester, a 17-year-old girl died in hospital on Monday morning after taking a form of ecstasy named 'MasterCard'. Reports say she took only one pill at the Victoria Warehouse club, and police have warned anyone else who has taken the drug should seek medical attention immediately.
Professor Pryce, from the faculty of social sciences at the University of Nottingham, wonders what really happened, however.
"I feel for the parents who want to believe their child," she told Julia Hartley-Brewer. "My experience is [taking only one tablet] is not necessarily the truth.
"I’ve never heard anybody admit to taking two or three."
Pryce has found many young people wouldn't question the use of drugs.
"Drug taking is not a major thing," she added. "They [young people] regard it as normal because their friends do it with no ill effect.
"Some drugs affect people more than they would others, so there's a variable impact of drugs."
Views on drugs mean similar incidents will most likely continue and the problem is not going to be solved easily. Pryce said there are many ways to tackle the issue.
"We could sell drugs in a regulated way, like alcohol," she pointed out. "You would still have some people who would die.
"There are things we could do to make them less harmful, like telling people what's in them, so it's not such a game of Russian Roulette."
