If you've experimented with LSD, you might wonder how long it will take to leave your system. In addition to how long a trip lasts, there's also the problem of drug tests. There are many factors that may influence how long LSD stays in your system, so here's a quick summary of them, as well as how LSD affects drug tests and what you can do about them.
How long does LSD stay in your system?
The typical LSD trip lasts for 6-12 hours, with this depending on a number of factors. Even when a trip ends, it doesn't mean you're clean of LSD.
Most drugs have what is called a half-life, which is the time it takes the body to half the amount of drug present. LSD is thought to have a half-life of around 3-5 hours, meaning that it takes the average person around 15-28 hours to become completely clean of LSD. That said, even if the body is 100% clean of LSD, some of its metabolites can linger for much longer.
Some factors that may influence how long LSD stays in your system
The numbers above are just guidelines based on the typical case. In reality, a number of factors may influence how long LSD stays in your system. Firstly, some people just metabolize things better thanks to their genetics, while others may need more time to metabolize LSD and expel it (and its metabolites) from their bodies.
Other factors include age, any other drugs being taken, the amount of LSD taken, and lifestyle. People who are more active also generally do better when it comes to flushing LSD from their system.
What about drug tests?
It's possible to test for LSD in urine and saliva for up to four days if it looks for the 2-oxo-3-hydroxy-LSD metabolite. LSD isn't part of the standard SAMHSA 5-panel test, but it is included in some extended drug tests. It can also be specifically tested for if requested.
The four-day period is just a guide of course. Some people may be clean much sooner, while others might take slightly longer. Home testing kits for LSD are not commonly available, so you won't be able to know for sure. We recommend taking some simple precautions before any drug test.
Preparing for a drug test
Various detox products can help you prepare for urine and saliva drug tests. About two hours before a urine test, you could use a detox drink to prepare your urinary system. These drinks stimulate the body's natural cleansing mechanisms and the production of clean urine, meaning you can safely take a urine drug test in the normal way without failing. Different detox drinks are intended for different body weights, so if you're a heavier person, be sure to get the right detox drink. Whichever detox drink you buy, always be sure to follow the directions.
Passing saliva drug tests can be even easier, because all you need to do is use a good detox mouthwash shortly before the test.
