Club drugs

This webpage looks at the effects of club drugs (or ‘recreational’ drugs), including legal highs.

These are substances which primarily act on the brain to make people feel euphoric, energised or relaxed.

They are commonly taken in nightclubs, at festivals, parties and are sometimes used by members of the lesbian, gay, bisexual and transgender (LGBT) community as part of their sex lives.

This information is aimed at:

  • people who use them
  • people who know someone who uses them
  • professionals who may be supporting someone who uses them.

The research about club drugs is limited. However, this webpage presents a summary of what is known about:

  • their good and bad effects
  • how users can reduce the risk of harm if using them
  • identifying who may need help
  • how to get help.

Club drugs are a group of drugs that primarily act on the brain. Some club drugs are well known, like cocaine, MDMA (ecstasy), mephedrone and ketamine.  

Groups of new club drugs are emerging all of the time. These are called ‘new psychoactive substances’ (NPS), the so called legal highs.

These are made specifically to mimic the effects of established drugs.

It is estimated that one new drug appears on the European drug market each week. Since these drugs are not regulated, it is hard to know exactly what each dose of drug contains.

Even people selling them don’t know this for sure. These are some of the reasons why the scientific evidence is limited.

Club drugs and the law

In 2015 the UK government made it illegal to produce, supply, offer to supply, possess with intent to supply, import or export psychoactive substances, including club drugs. The maximum sentence will be 7 years’ in prison.

Who uses club drugs?

Up to 1 million people may use club drugs each year in the UK. This figure is increasing, and some drugs like mephedrone and ketamine are more and more popular.  

These drugs are most commonly used by students, members of the LGBT community, and people who identify themselves as ‘clubbers.’

People typically use club drugs for their positive effects. They can increase energy levels, lift mood or alter the sensations they experience, which is why they are popular in social settings. 

Because many of them are quite new, the harmful effects are still unclear. However, it is increasingly clear that they can be as harmful as well-known drugs, such as heroin and crack cocaine.

In 2013, over 400 people in England and Wales died after taking club drugs, some of whom were taking club drugs for the first time.

Toxic reactions, damage to internal organs, overdoses, heart problems, mental health problems and dependence have all been seen in club drug users. 

The information below shows examples of club drugs and effects.

The simplest way to avoid the risks of taking club drugs is not to take them. For people who use these drugs, there are simple rules that can reduce, but not remove the risk of harm.

  • Tell someone what/how much you are taking.
  • Don’t use alone.
  • Look after one another.
  • Start with a small test dose and wait at least an hour before taking anything else.
  • Avoid mixing drugs and avoid drinking alcohol at the same time.
  • Drink sips of water: don’t drink more than 1 pint per hour.
  • Ask for help if you are feeling unwell, be honest about what you have taken.
  • Sleep on your side and put sleeping/unconscious friends in the recovery position. Information about how to put someone in the recovery position can be found on the NHS choices website.
  • Think about the essentials: condoms, money to get home safely.
You may want to think about your drug use, and whether it is something to worry about.

Here are ten questions for you to answer about your drug use (excluding alcohol) over the past 12 months. Circle the response that is mostly right.

1. Have you used drugs other than those required for medical reasons?YesNo
2. Do you use more than one drug at a time?YesNo
3. Are you always able to stop using drugs when you want to?YesNo
4. Have you had 'blackouts' or 'flashbacks' as a result of drug use?YesNo

10. Have you had medical problems as a result of your drug use (e.g. memory loss, hepatitis, convulsions, bleeding etc...)YesNo

Taken from DAST-10 (see references).

Score 1 point for each ‘yes,’ except for question 3, for when a ‘no’ scores 1 point.
