Drugs and Alcohol Abuse — Core Principles
Core Principles
Drugs and alcohol abuse involves the harmful use of psychoactive substances, leading to adverse health, social, and psychological outcomes. Key substances include opioids (e.g., heroin, morphine from Papaver somniferum), cannabinoids (e.
g., marijuana, hashish from Cannabis sativa), stimulants (e.g., cocaine from Erythroxylum coca), and hallucinogens (e.g., LSD from Claviceps purpurea). These substances primarily affect the central nervous system by interacting with specific neurotransmitter systems and receptors, altering mood, perception, and behavior.
Abuse can lead to tolerance, physical dependence (withdrawal symptoms upon cessation), and psychological dependence (strong craving). Chronic abuse results in severe health consequences like liver damage (cirrhosis), neurological impairment, cardiovascular issues, and mental health disorders.
Adolescents are particularly vulnerable due to ongoing brain development and peer pressure. Prevention involves education, counseling, and fostering a 'Say No' attitude to resist peer pressure and avoid experimentation.
Important Differences
vs Drug Abuse vs. Drug Dependence
| Aspect | This Topic | Drug Abuse vs. Drug Dependence |
|---|---|---|
| Definition | Drug Abuse: Harmful pattern of drug use, often non-medical or excessive, leading to negative consequences. | Drug Dependence: A state (physical or psychological) where the body or mind relies on a drug to function normally, often accompanied by tolerance and withdrawal. |
| Nature | Behavioral pattern of misuse. | Physiological and/or psychological adaptation to the drug. |
| Withdrawal Symptoms | Generally not present or mild if use stops. | Characteristic and often severe withdrawal symptoms upon cessation. |
| Tolerance | May or may not be present. | Typically present, requiring increasing doses for the same effect. |
| Reversibility | Easier to cease use with intervention. | Much harder to cease due to physical/psychological cravings and withdrawal. |
