Study Notes

Stimulants

Stimulants are a category of psychoactive drugs that enhance alertness and energy.
They act by blocking the reuptake of key neurotransmitters: dopamine, norepinephrine, and serotonin.
This action occurs in the synapses, facilitating increased communication between neurons in the central nervous system.

Depressants

Depressants are psychoactive drugs that lower the activity level of the central nervous system (CNS).
These substances can promote relaxation, decrease anxiety, and induce sedation.
Common examples include alcohol, benzodiazepines, and barbiturates.

Opioids

Opioids are chemicals that engage opioid receptor neurons, located in the brain and digestive system.
Their effects include producing euphoria, analgesia (pain relief), and slower breathing rates.
Opioids can also lead to constipation, a common side effect due to their action on the digestive system.

Hallucinogens

Hallucinogens are a class of psychoactive drugs that significantly alter sensation and perception.
They can cause visual and auditory hallucinations, changing a person's experience of reality.
Common examples include LSD, psilocybin (magic mushrooms), and mescaline.
