i have a son that takes percocet,s and xanax and i want to drug test him so i need to no how long it stays in him
In an obese group of subjects the half-life of Xanax (alprazolam) ranged between 9.9 and 40.4 hours (mean=21.8 hours, n=12) as compared to between 6.3 and 15.8 hours (mean=10.6 hours, n=12) in healthy subjects. The half-life of alprazolam is approximately 25% higher in Asians compared to Caucasians.
48 hours for the Percocet and about 10 hours for the Xanax. His age and activity level are also a factor. I weigh 210 lbs. and am not very active, but in a recent drug test I did not test positive for either drug because I had used all my Percocet 2 days earlier and had taken Xanax before I had gone to bed the night before. I hope this is helpful.
