The effect of recreational drugs

The Effects of Stimulant Drugs

Stimulants such as cocaine and amphetamines increase neurotransmitter activity in the brain.
They stimulate the central nervous system (CNS), promoting alertness, attention, and elevated mood.
Stimulants increase the amount of neurotransmitters like dopamine and norepinephrine in the synaptic cleft by blocking their reuptake, leading to prolonged effects of these neurotransmitters on the post-synaptic neuron.
Prolonged use of stimulants can lead to neurotransmitter depletion, causing ongoing psychological effects, such as depression and anxiety.

Substances like alcohol and benzodiazepines are known as depressants. They decrease neurotransmitter activity, producing a calming effect and reducing anxiety and tension.
Depressants increase the activity of the neurotransmitter GABA and decrease the activity of the neurotransmitter glutamate.
Long-term use of depressants can lead to physical dependence and withdrawal symptoms when the substance is not consumed.
Chronic alcohol usage may lead to deficits in cognitive and motor functions, including difficulty with memory and motor coordination.

Hallucinogenic Drugs like LSD (Lysergic acid diethylamide) and psilocybin act primarily on serotonin receptors in the brain.
They can have profound effects on perceptions and can produce hallucinations, or sensorial experiences that are not real.
Changes in thought, mood, and sensory perception can be associated with the release of serotonin in different areas of the brain.
Tolerance to these drugs grows rapidly, requiring users to take larger quantities to achieve the same effect, and withdrawal effects can include depression and anxiety.
