Activity of the NMDA system is implicated in numerous brain functions, including sensory perception, memory and levels of consciousness, and is inhibited by alcohol. On acute withdrawal of alcohol this results in excitatory effects via, respectively, an increased calcium flux and a reduced chloride shift in CNS neurons . Drinking in moderation has been found to help those who have had a heart attack survive it. However, excessive alcohol consumption leads to an increased risk of heart failure. A review of the literature found that half a drink of alcohol offered the best level of protection.

The molecular and biochemical mechanisms by which chronic alcohol consumption leads to the development of cancers of various organs are not fully understood. It likely plays an important role in the development of cancers of the digestive Alcohol misuse tract, especially those of the upper digestive tract (Lachenmeier et al. 2009; Seitz and Becker 2007). Brain damage may also occur through alcohol-induced nutrition deficiencies, alcohol-induced seizures and liver disease.

Giving into peer pressure can lead to drinking problems down the road, as well as many health complications that arise from excessive alcohol consumption.

This is especially true when adolescents engage in frequent binge drinking. While drinking early on can increase the likelihood of alcohol abuse, alcoholism can affect anyone at any age.

A meta-analysis determined the dose-response relationships by sex and end point using lifetime abstainers as the reference group. Compared with lifetime abstainers, the relative risk for type 2 diabetes among men was most protective when consuming 22 g/day alcohol and became deleterious at just over 60 g/day alcohol.

Long-term effects of alcohol

Social skills are significantly impaired in people that have alcoholism due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. A study found that moderate consumption of alcohol had a protective effect against intermittent claudication. The lowest risk was seen in men who drank 1 to 2 drinks per day and in women who drank half to 1 drink per day.

On the other hand, heavy alcohol use occurs when a person binge drinks on five or more days during a month. The liver can only process approximately one alcoholic drink per hour.
