Drugs
Smoking
Diseases Caused by Smoking: Lung cancer, chronic obstructive pulmonary disease (COPD), heart disease, and stroke
Tar: Coats the lungs and contains carcinogens, increasing the risk of cancer.
Carbon Monoxide: Reduces the blood's ability to carry oxygen, leading to shortness of breath and cardiovascular issues.
-
Effects on the Lungs: Smoking damages the lungs' structure, leading to diseases like chronic bronchitis, emphysema, and lung cancer. It impairs the lungs' ability to exchange gases effectively.
What do drugs do?
Depressants: Slow down brain activity, leading to relaxation, reduced anxiety, and drowsiness. They decrease alertness and can impair coordination and reaction times.
Stimulant: Increase activity in the brain, leading to increased alertness, energy, and wakefulness. They speed up messages between the brain and the body.
Painkillers: Block or reduce the sensation of pain by interfering with the nervous system's transmission of pain signals.
Performance enhancers: Enhance physical abilities by increasing muscle mass, stamina, or recovery rates, often used illegally in sports to gain an unfair advantage.
Effects of Heroin Abuse
Addiction and Withdrawal: Heroin is highly addictive, with severe withdrawal symptoms including muscle pain, vomiting, and intense cravings.
Depressant Effects: It depresses the central nervous system, slowing heart rate and respiration, leading to a state of drowsiness.
Effect on the Brain: - binds to opioid receptors, leading to euphoria.
Chronic use alters brain structure and function, particularly affecting the reward system
Heroin impacts the nervous system by slowing down the communication between neurons. At synapses, it increases dopamine levels, leading to a feeling of euphoria but also altering brain chemistry, leading to dependence.
