Step-by-step explanation:
The most common population affected by alcohol dependence is teenagers and young adults. This age group is more likely to engage in risky behaviors and experimentation with alcohol. However, it is important to note that alcohol dependence can occur at any age.
It is crucial to understand that alcohol consumption should be done in moderation and only by adults of legal drinking age. The immediate effects of alcohol depend on the individual's blood alcohol concentration (BAC), which can vary based on factors like age, sex, and overall health.
Excessive alcohol consumption can have various negative consequences, such as impaired coordination, blurred vision, aggressive behavior, and increased risk of accidents. Additionally, heavy drinking can lead to long-term health problems like liver cirrhosis and certain forms of cancer.
