Estimating how long peyote is detectable in the body depends on many variables, including which kind drug test is being used. Peyote - also known as mesc, peyote, peyote buttons, broken, dead - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting peyote in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time peyote will show up on a drug test.

The following is an estimated range of times, or detection windows, during which peyote can be detected by various testing methods:

How Long Does Peyote Stay in the Urine?

Peyote can be detected in the urine for 2-3 days

How Long Can Peyote Be Detected in Blood?

There is some data available that indicates Peyote can be detected in the blood for up to 24 hours.

How Long Can a Saliva Test Detect Peyote?

A saliva test can detect Peyote for up to 1-10 days

How Long Can a Hair Test Detect Peyote?

Peyote, like like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

Preventing Peyote Side-Effects

Peyote is a small cactus for which the principal active ingredient is mescaline. Mescaline can also be manmade through chemical synthesis. The dried peytoe buttons are usually dried and then chewed or made into a liquid or tea for consumption.

Enough mescaline to produce hallucinogens is very small - usually 0.3 to 0.5 grams.

The effects last about 12 hours, but it remains in the system for a much longer time.

The effects of peyote can be similar to those of LSD, including:
