Alcohol, Tobacco, and Other Drugs Effects
Learning Objective
I can analyze the short-term and long-term effects of alcohol, tobacco, and other drugs on the body and mind.
Key Concepts
When smoking cigarettes, tar damages tooth enamel and causes decay, while smoke damages nerve-endings in the nose, causing loss of smell.
Nicotine in cigarettes causes the release of dopamine and other neurotransmitters, which creates pleasurable sensations and makes smoking highly addictive.
Quitting smoking can lead to anxiety and depression due to nicotine withdrawal, but nicotine replacement therapy, counseling, and exercise can help smokers stay cigarette-free.
