Back in March 2010, Prime Minister of the UK, Gordon Brown, promised a crackdown on the drug that was categorized as a class B substance, second highest level of illegal narcotics in the UK. This classification carries a five-year jail sentence for users and places it in the same class as amphetamines and marijuana. The deaths of several teenagers in the UK were at the root of PM Brown and the National Association of Head Teachers" ban. What is Mephedrone? Similar to the effects of more familiar "party drugs" such as cocaine, amphetamines, and MDMA, mephedrone provides the user with a euphoric sensation lasting, on average, two to four hours. Other than meow meow, this relatively new street drug is also known as "MCat," and "drone." It comes in crystal, capsule, or powder form and can be either swallowed or snorted. It has been linked to several deaths in the UK, Europe, and Australia. In spite of its initial rush of euphoria, mephedrone users tend to develop a psychological dependence and often experience anxiety and paranoia. The drug can also lead to more severe health concerns including nausea, vomiting, blurred vision, memory loss, insomnia, increased heart rate, tremors, and lack of energy. The effects of mephedrone depend on the weight, height, and overall health of a person in addition to the amount that was taken and if it was combined with alcohol or any other drugs.
