The majority of illicit drugs consumed in the United Kingdom fall under one of four categories. These categories include opiates, hallucinogens, stimulants, and depressants. All of these drugs are highly addictive. Many of these drugs induce dependency when consumed on two or three occasions and many are defined by how they affect the human body when consumed. The precise properties of each category will be discussed throughout this section of the website.


Opiates are well-known for their pain relieving properties. However, opiates are commonly abused because opiates interact with the pleasure centres in the brain. This means opiates allow people to experience feelings of euphoria when consumed. Common opiates consumed in the United Kingdom include methadone, heroin, opium, fentanyl, and tramadol. heroin rehab treatment is usually required when an addiction arises.


Hallucinogens are known to alter users’ view of reality. Common hallucinogens consumed in the United Kingdom include LSD, cannabis, magic mushrooms, and ecstasy.


Stimulants affect users’ central nervous system. When stimulants are consumed, users experience a sense of euphoria and an enhanced feeling of improved well-being. Stimulants also improve motor and mental activity. Common stimulants consumed in the United Kingdom include crack cocaine, cocaine, ecstasy, and amphetamines.


Depressants have a reverse effect when compared to stimulants. Unlike stimulants which speed up the central nervous system, depressants act by slowing down the central nervous system. When the central nervous system is slowed down, brain activity is also suppressed. This causes users to experience a sense of calm and relief from stress. If users suffer from anxiety, the symptoms of anxiety will also temporarily disappear when under the influence of depressants. Examples of depressants include cannabis, benzodiazepines, barbiturates, and alcohol.
