Which drugs are used most?

The most commonly used mood altering drug used in the UK is caffeine

Our favourite drugs

Caffeine is our favourite drug. It is contained in tea, coffee, many soft drinks and colas, some confectionery, included in many medicines and available in over-the-counter stimulant preparations such as Pro Plus.

Apart from medicines in general the next most commonly used drug is alcohol, followed by the nicotine in cigarettes and other tobacco based products.

These and other drugs can be broadly categorised in a way that helps with understanding how a person might be affected when using them:

Depressants

Such as alcohol, tranquillisers, heroin, methadone and solvents slow down the central nervous system, affecting co-ordination and reaction times. Alcohol, for instance, used to create feelings of relaxation and disinhibition in social settings, can be inappropriate and cause problems in the workplace. Due to slow reactions, depressant use is particularly dangerous whilst driving or operating machinery.

Stimulants

Such as amphetamines ('speed'), ecstasy, cocaine, mephedrone. tobacco and caffeine increase the heart rate and give the user a sense of increased alertness and energy. People using some stimulants can become aggressive. Illicit stimulants might be used recreationally but the following day at work, a user can feel tired or depressed. Employees may also use stimulants to enable them to work long shifts but repeated and regular use could lead to problems or dependence.

Hallucinogens

Such as cannabis, ketamine and 'magic mushrooms' change the way people think, feel and perceive their surroundings. They can enhance appreciation of surroundings but can also cause anxiety or paranoia. As they can distort the user's sense of time and perception, these drugs would again be dangerous in 'safety critical' jobs. Whilst none of the hallucinogens mentioned cause physical dependence, a user may become psychologically dependent on their effects. Cannabis is the most commonly used illegal drug in the UK.
