Xanax effects many different aspects of an individual. The major concern about Xanax has been "idiosyncratic reaction." People taking Xanax can become uninhibited, violent, or have marked personality changes. This is why Xanax is prohibited in the UK. In general, Xanax will sedate the user. Many people use Xanax to lower their inhibitions the same way that others use alcohol. Both Xanax and alcohol are depressants and in low doses they tend to make the user feel more relaxed and sociable. Unfortunately, as with any depressant, tolerance develops from prolonged use. The user needs larger & larger dosages to feel sedated which greatly increases the risk of severe side effects.
