• 肝病：由于多年的酒精使用或其他健康状况导致患有慢性肝病的人们在他们的身体中较难以突破药物，导致健康成年人近20小时的半衰期。
• 代谢: People with a higher metabolism, for example, those who are physically active, tend to be able to excrete Xanax faster. Hydration, age, and other health conditions may also play a role in a person's metabolic rate.
• Smoking cigarettes: The concentration of Xanax in the blood is up to 50% less in smokers than non-smokers.
• Weight: When you’re overweight, it’s more difficult for your body to break down Xanax, which can increase the half-life of the drug.
