Mephedrone Addiction: The Causes, Symptoms and Impacts

Remember when everyone was talking about that party drug that smelled like cat wee? That was mephedrone. Its peak in the UK might have passed over a decade ago but it hasn’t vanished. It’s still out there, still finding its way into parties and the wrong hands across Europe.

What is mephedrone?

Mephedrone, often called ‘meow meow’ or ‘MKAT’, is a synthetic stimulant from the cathinone family. It first gained popularity in the UK’s party and clubbing scenes for its intense bursts of energy and sociability at a very low cost. 

Before its ban in 2010, it was often sold online as “plant food” or “bath salts” to bypass regulations but today, it is classified as a Class B drug in the UK.

While its effects can initially feel appealing, mephedrone is far from harmless. Its stimulant properties strain both the heart and mind and its short-lived high often leaves users chasing the same feeling, sometimes within minutes. 

Understanding its risks is the first step in recognising when casual use is starting to turn into something more serious.

How does mephedrone affect your body?

Mephedrone works by flooding the brain with dopamine and serotonin, which produces an intense high, often described as a wave of euphoria and heightened confidence. However, these effects come at a cost. 

Physical impacts include increased heart rate, raised blood pressure, teeth grinding, excessive sweating and overheating. Over time, these stresses can lead to more serious issues such as cardiovascular strain or damage to the nervous system.

The comedown is another challenging aspect of mephedrone use. Once the high fades, users often experience sudden fatigue, low mood, irritability and strong cravings to take more. This cycle of short-lived euphoria followed by emotional and physical crashes can quickly pull a person toward dependency.

Is mephedrone addictive?

Mephedrone has a high potential for addiction. Its rapid onset and short duration encourage repeated use in a short space of time, with many people taking dose after dose in one session. This binge pattern not only increases the risk of harmful side effects but also speeds up the development of tolerance, where larger amounts are needed to feel the same effects.

As mephedrone is a stimulant, addiction can develop both physically and psychologically. Physically, the body becomes accustomed to having mephedrone in its system, leading to withdrawal symptoms such as fatigue, depression, anxiety and intense cravings when use stops. Psychologically, many come to rely on the drug to feel confident or sociable, making the idea of quitting feel daunting.

The reality of mephedrone use in the UK

In recent years, mephedrone use has surged again in parts of Eastern Europe, where it’s cheap, easy to find and carries a reputation for delivering a powerful high. In countries like Russia and Georgia, this rise has been fuelled by lower-quality alternatives disappearing from the market and the growth of dark web sales. More worryingly, the way it’s taken has shifted, with injecting becoming far more common and the risks of psychosis, dependence and fatal overdoses increasing. 

While this is happening abroad, it’s a reminder of how quickly trends can cross borders. In the UK, where the cost of living is pushing people away from expensive party options like cocaine, a drug that can be bought for a fraction of the price could easily tempt new users, especially if they’re unaware of how destructive it can be.

Am I addicted to mephedrone?

For some, mephedrone use can feel harmless at first. You might only take it to feel more confident in social situations or to make a night out last longer. The problem is that this is often exactly where addiction begins. 

While we do not condone the use of any illegal drug, if you are already using mephedrone, it is important to check in with yourself regularly to make sure it is not starting to take more from your life than it gives.

Ask yourself the following:

If you recognise yourself in these questions, it is important to act now rather than waiting for things to get worse. Seeking out rehab treatment could make the difference between regaining control or slipping deeper into dependence.
