Researchers have attempted to develop a different method


LSD can generally be detected in urine tests within eight hours of use and up to two to four days after use.

Researchers discovered LSD in blood samples obtained 16 hours after individuals were administered 200mcg of LSD in one trial. 3 Researchers were able to identify the chemical in blood testing 8 hours after administering a lesser amount of 100mcg. Because levels gradually reduce over time, the capacity to identify the drug decreased significantly after 16 hours. does acid show up on a drug test?

LSD, like many other substances, can be detected for up to 90 days using a hair follicle drug test. Hair testing, on the other hand, is quite uncommon. Because the medication is frequently administered in such small dosages, it can be difficult to detect in both research and forensic contexts. While hair tests are occasionally used to screen for LSD, they are expensive and the findings might be inaccurate. 5
