Study Notes
Stimulants
- Psychoactive drugs that enhance alertness and energy levels.
- Function by blocking the reuptake of neurotransmitters: dopamine, norepinephrine, and serotonin.
- Increased presence of these neurotransmitters in synapses results in heightened mood and focus.
Depressants
- A class of drugs that diminish overall brain and body activity.
- Primarily depress the Central Nervous System (CNS), leading to relaxation and reduced anxiety levels.
- Commonly used for conditions such as insomnia, anxiety, and muscle spasms.
Opioids
- Chemicals that activate opioid receptors in the brain and digestive system.
- Effects include euphoria (intense happiness), analgesia (pain relief), slower breathing, and constipation.
- Often utilized in pain management, but carry a risk of addiction and overdose.
Hallucinogens
- Psychoactive substances that disrupt normal sensory processing.
- Alter sensations and perceptions, leading to experiences that may seem unreal or distorted.
- Can evoke visual and auditory hallucinations, affecting thoughts, emotions, and self-perception.
