When alcohol enters in your system then your body will start to metabolise it. Metabolise is the body chemical process for breaking down a substance to be absorbed or used as energy. This whole process happens when you consume any food or drink. There are two commonly asked questions regarding alcohol in the body. “How long does alcohol stay in your system?” and “How long does alcohol stay in your blood?”. These questions are asked for several reasons. Alcohol is a depressant that has a short life span in our body. Once the alcohol has entered in your bloodstream then it will metabolize an amount of alcohol every hour. This totally depends on the individual and it also includes other factors like liver size and weight. For treatments and medications rehab centers are available at your nearby places.
