Study Notes

Stimulants

Operate by blocking reuptake of neurotransmitters: dopamine, norepinephrine, and serotonin.
Affect the synapses in the central nervous system, resulting in heightened alertness and energy.

Depressants

Reduce overall activity of the Central Nervous System (CNS).
Lead to effects such as relaxation, lowered inhibitions, and sedation.

Opioids

Chemicals that enhance activity at opioid receptor neurons.
Key effects include euphoria, pain relief (analgesia), slower respiratory rate, and potential side effects like constipation.
Commonly used for pain management but carry risks of addiction.

Hallucinogens

Psychoactive substances that significantly alter a person's sensations and perceptions.
May produce visual or auditory hallucinations and changes in thought processes and emotions.
