Xanax (alprazolam) belongs to a group of drugs called benzodiazepines. It works by slowing down the movement of chemicals in the brain that may become unbalanced. This results in a reduction in nervous tension (anxiety). This drug is used to treat anxiety disorders, panic disorders, and anxiety caused by depression. Because this drug can easily be addictive, people tend to get hooked on it. Where going off of it becomes extremely hard for many patients. Xanax is not made to make you feel good, but it completes it's job by relaxing you altogether, which is why people abuses it.
