Study Notes
Stimulants
- Stimulants are a class of drugs that increase the activity of the central nervous system (CNS). They generally have arousing, alerting, and mood-elevating effects.
- Common stimulants include amphetamines (e.g., methamphetamine, amphetamine), cocaine, and nicotine.
- Mechanism of action: Stimulants typically increase dopamine and norepinephrine levels in the brain, leading to heightened alertness, focus, and energy.
- Effects: Increased heart rate and blood pressure, elevated mood, decreased appetite, insomnia, anxiety, and paranoia (in higher doses or with addiction).
- Potential for addiction/dependence: Many stimulants have a high potential for addiction, due to the intense reward pathways they activate in the brain. Tolerance develops quickly, meaning that larger and larger doses are needed to achieve the same effect.
- Withdrawal symptoms can be severe, including fatigue, depression.
- Medical uses: Some stimulants have legitimate medical applications, such as treating ADHD (e.g., methylphenidate) and narcolepsy.
- Risks: Cardiovascular issues (e.g., heart attack, stroke), psychosis, seizures are among severe associated risks.
Depressants
-
Depressants are drugs that slow down the activity of the central nervous system (CNS), reducing alertness and responsiveness.
-
Common depressants include alcohol, barbiturates, benzodiazepines (e.g., Xanax, Valium), and opioids (e.g., heroin, morphine).
-
Mechanism of action: Depressants generally affect neurotransmitter systems, slowing down the communication between neurons in the brain.
-
Effects: Reduced heart rate and breathing, drowsiness, impaired judgment, slurred speech.
-
Potential for addiction/dependence: Many depressants are habit-forming, producing tolerance and withdrawal symptoms.
-
Withdrawal symptoms can range from mild anxiety to severe seizures or even death.
-
Medical uses: Some depressants have legitimate medical uses, such as treating anxiety, insomnia, and seizures.
-
Risks: Respiratory depression, overdose (can lead to coma or death), slowed reflexes, impaired judgment.
-
Alcohol's effects on the body are varied and complex. In moderate use, it can have social lubricant effects. Heavy use can damage the liver, brain, and other organs.
-
Interactions: Depressants can interact dangerously when taken with other drugs including stimulants, increasing the risk of severe adverse effects. It's important to note the potential for combined overdose.
Commonalities & Distinctions
- Both stimulants and depressants have the potential to lead to addiction, dependence, and, in extreme cases, death.
- Both classes should be handled with extreme caution and only under direct medical supervision.
- Misuse of either class can lead to serious health complications and significant disruption to daily life and social relationships.
- Although they have varied mechanisms of action, both classes of drugs ultimately target and alter neurochemical processes in the central nervous system to bring about their characteristic effects.
