Green Xanax bars are considered short-acting benzodiazepine drugs. After taking these pills, peak levels are found in your blood vessels after 1 or 2 hours. The average half-life of Green Xanax pills in the blood is 11.2 hours in healthy people.
The half-life of a drug indicates an estimated time that our body takes to clear the half part of a tablet.
It takes almost five half-lives for 98 percent of a drug dose to clear the entire body, so a Green Xanax tablet takes 2 to 4 days to be eliminated from the body.
Alprazolam is detectable in your saliva, blood, urine, and hair, but how long it's detectable depends upon different factors. Green Xanax is cleared from our other body parts at different rates.
General timelines may be as;
Blood: Up to 24 hours
Hair: Up to 90 days
Urine: Up to 4 days
Saliva: Up to 2.5 days
Blood levels may be considered a screening test or in case of treatment for a suspected overdose, but they can only be detected if you have taken Green Xanax in the last 24 hours.
Like all other benzodiazepines, Green Xanax bars can be detected in your hair as well. It lasts up to 90 days in our hair after the last dose.
Green Xanax is also found in our saliva for a short period. It can be seen in your saliva for up to 2.5 days.1
Like those done for employment, a urine drug screen will test positive for most benzodiazepines for up to 5 days and up to a week after a dose. For patients who metabolize Green Xanax slowly—like the obese, elderly, and those with alcoholic liver problems—that time maybe even longer.
