Alcohol is considered a drug because it acts as a depressant. Under the influence of heavy alcohol, the speech becomes slurred and there is loss of coordination and control on movements.
Alcohol is a drug because when it is absorbed into the body, it modifies the normal functions of the body. Alcohol is the most harmful drug followed by crack cocaine and heroin, according to CNN, and, according to published reports, it is three times as harmful as cocaine or tobacco. Nearly 100,000 Americans die every year as a result of alcohol abuse.
Alcohol is a depressant as it acts on the central nervous system, making the person lose consciousness. Under heavy doses of alcohol, the respiratory cells in the brain become numb. In this case, the autonomic nervous system collapses and the brain signals the body to stop breathing. As a result, the person may suffer from suffocation and even die due to alcohol overdose.
Alcohol neither stimulates nor does it act as a mood enhancer. In fact, it decreases the energy levels of the body and people become abusive and aggressive after drinking alcohol. They lose their ability to think rationally under the influence of alcohol.
