Psychoactive substances influence the function and interaction of one or more neurotransmitters in the brain. Depending on the type, dose, and combination of medications used as well as the individual's qualities, expectations, and environment, this can have a variety of consequences on the user's mental and physical health.

<h3>What is a psychoactive drug?</h3>

A psychoactive substance is one that modulates brain activity and has an impact on behavior, cognition, mood, or perception. Based on their results and modes of action, psychoactive substances can be divided into a variety of categories. Stimulants, depressants, opioids, hallucinogens, and cannabis are a few of the main groups.

Neurotransmitters are chemical messengers that transmit impulses between neurons (nerve cells) in the brain and other regions of the nervous system.

Psychoactive medications act on one or more neurotransmitters. The neuron sending the signal, the presynaptic neuron, releases neurotransmitters, which then bind to receptors on the postsynaptic neuron.

Depending on the type of neurotransmitter and receptor involved, this can either stimulate or inhibit the postsynaptic neuron.
