Some negative effects of alcohol include a less productive professional life, broken homes, health complications and financial problems. Drinking small amounts of alcohol may have little or no negative effect. However, too much drinking inevitably leads to problems, notes the National Institute on Alcohol Abuse and Alcoholism.
Drinking too much alcohol often leads to health complications because of the chemical content of the substance, notes the Foundation for a Drug-Free World. Organs such as the heart, liver, brain and kidney may end up being damaged. Depending on the amount of alcohol consumed, the damage may occur over a short or longer period of time. While some health issues may be treated, other complications may become chronic and lead to poor quality of life or death.
Individuals who drink a lot risk becoming dependent on the drink. This means they are no longer able to carry out professional or academic duties. Such individuals often feel the urge to drink even at odd hours.
Drinking alcohol impairs human judgment. This can easily lead to car accidents or other forms of accidents which may cause harm to the individual drinking and those around. In certain cases, family units fall apart due to a member with an alcohol problem.
