How long LSD is detectable in the body depends on several variables, including which kind drug test is being used. LSD - also known as acid and microdot - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

How often the drug has been taken, how much as been used, and the potency of the dosage can also possibly play a role in how long LSD might be detected by a drug test.

The timetable for detecting LSD 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 LSD will show up on a drug test.

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

How Long Does LSD Stay in the Urine?

LSD can be detected in the urine for 8-24 hours

How Long Can LSD Be Detected in Blood?

LSD can show up in a blood test for up to 3 hours.

How Long Can a Saliva Test Detect LSD ?

A saliva test can detect psilocybin for up to 1-2 days

How Long Can a Hair Test Detect LSD?

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

It Is Important to Know How Long LSD Lingers

If a large dose of LSD is taken it can produce some very unpleasant effects, sometimes called a "bad trip." Of course, some users can experience a bad trip no matter what dosage they consumed.

LSD can produce delusions and visual hallucinations, which can cause some users to panic. Users can experience severe, terrifying thoughts and feelings of despair, fear of losing control, or fear of insanity and death.

Side-effects of LSD include raised body temperature and increased heart rate and blood pressure.

LSD can cause profuse sweating, loss of appetite, sleeplessness, dry mouth, and tremors.

One danger of LSD use is a condition called hallucinogen-induced persisting perceptual disorder (HPPD) in which flashbacks persist and produce distress or impairment for the user in social or occupational functioning.
