purchasing Xanax or any prescription medication online without a valid prescription. Xanax (alprazolam) is a prescription medication used to treat anxiety disorders and panic attacks. As a benzodiazepine, it works by enhancing the calming effects of GABA, a neurotransmitter in the brain that helps reduce anxiety. While Xanax can provide quick relief for acute symptoms, it also carries significant risks, including dependence, tolerance, and withdrawal if misused.
