Hallucinogens are sometimes also known as hallucinogenic substances or ‘psychedelic and dissociative drugs.’ These names refer to drugs that ‘can temporarily alter a person’s mood, thoughts, and perceptions.’
This can lead to changes in the way that we:
- Taste
- Smell
- Hear
- Feel
- See
things around us. On a very basic level, hallucinogens have the power to change the way that we perceive and interact with the world. For some people, this can lead to a heightening of the senses. This may mean that colours look brighter, we are more receptive to touch, and sounds feel louder and more pleasurable. This sensory-boosting effect is thought to be the primary driver of the use of psychedelics, especially in clubs, bars, festivals, music or other ‘party’ settings.
Alongside this heightening of sensory information, a psychedelic high may also produce hallucinations (hence the term ‘hallucinogen’). A hallucination is when someone perceives something that other people do not. This could look like:
- Seeing something that is not there (known as visual hallucinations)
- Hearing voices or sounds that other people do not (auditory hallucinations)
- Smelling something that is not present (olfactory hallucinations
- Tasting something that you have not eaten (gustatory hallucinations)
- Feeling sensations that have no outside cause (tactile hallucinations)
People using hallucinogens may also note that their emotional state changes. The emotional response experienced can vary widely from a sense of peace and calm to palpable fear. Some individuals find that using hallucinogens provides them with a type of spiritual enlightenment. Others find that it provokes paranoia and panic which can threaten both their physical and mental safety. This is often described as an ‘idiosyncratic reaction.’ This unpredictability makes the use of hallucinogens particularly risky. You may find that one use produces euphoria, whilst another use can feel darker and more uncomfortable.
Whilst reactions to different hallucinogens can be very broad, each type of psychedelic drug is associated with ‘typical’ effects.
