Drug abuse has profound and wide-ranging impacts on health, affecting virtually every organ system in the body. These effects can be acute (short-term) or chronic (long-term) and vary depending on the type of drug, the method of administration, the duration of use, and the individual’s overall health.

Examples and impact of drug abuse on health

(1) Cardiovascular System:- for Example; Cocaine Use, Therefore Cocaine causes a range of cardiovascular problems including arrhythmias, heart attacks, and increased risk of stroke.
Mechanism:- It constricts blood vessels, increases heart rate and blood pressure, and can lead to a heart attack even in young, healthy individuals.

(2) Respiratory System:-
For Example; Smoking Tobacco, it Impact Chronic obstructive pulmonary disease (COPD), lung cancer, and other respiratory infections.
Mechanism:-The tar and chemicals in tobacco smoke damage the airways and lung tissue, leading to chronic inflammation, reduced lung function, and carcinogenesis.

(3) Neurological System:- For Example; Methamphetamine Use,
It Impact Severe dental problems (“meth mouth”), skin sores, weight loss, and neurological issues such as memory loss, aggression, and psychosis.
Mechanism:- Methamphetamine increases the amount of dopamine in the brain, which stimulates brain cells but also causes significant neurological damage over time.

(4) Liver:- For Example; Abuse can lead to hepatitis, fatty liver disease, cirrhosis, and liver cancer.
Mechanism:- Chronic alcohol consumption leads to the accumulation of fat in liver cells, inflammation, and scarring (fibrosis), ultimately resulting in liver failure.

(5) Gastrointestinal System:- For Example; Opioid Use,
It Impact Severe constipation, nausea, vomiting, and abdominal pain.
Mechanism:- Opioids slow down the gastrointestinal motility, leading to bowel dysfunction and discomfort.

(6) Immune System:- For Example: Injection Drug Use (e.g., Heroin)
Impact, Increased risk of infectious diseases like HIV/AIDS, hepatitis B and C, and bacterial infections.
Mechanism:- Sharing needles and the unhygienic conditions associated with drug use lead to the spread of bloodborne pathogens and other infections.

(7) Mental Health:- For Example: Cannabis Use,
Increased risk of anxiety, depression, and in some cases, psychosis.
Mechanism:- While some use cannabis for its perceived benefits on mood, heavy use, particularly during adolescence, can alter brain development and lead to mental health disorders.

(8) Reproductive System:- For Example; Anabolic Steroid Abuse,
Therefore it Impact, Infertility, testicular atrophy, and menstrual irregularities.
Mechanism:- Steroids disrupt the normal production of hormones, leading to reproductive system dysfunction and secondary sexual characteristic changes.

Drug abuse affects every organ system, leading to both acute and chronic health issues.
