LSD Is Literally Getting Stuck In Your Brain


Most famous hallucinogenic LSD is know for the long lasting effect.

LSD’s hallucinogenic effects last an unusually long amount of time; 12 to 18 hours, which is longer than any other hallucinogen.

And the reason why it lasted that long was a mistery to scientist that let to drug reasearch that started in 60s and 70s.

Only in the latest study presented on Popular Science, the scientist claim to have found the key solution. Once ingested, LSD travels into brain receptors where it gets stuck—literally stuck—within a side pocket. This new understanding, they say, could help them to develop new, longer-lasting drugs to treat a variety of psychological disorders.

When researchers first began studying LSD, something tripped them up: The half-life (the amount of time a drug can be found in someone’s blood) for LSD is only about a half hour to an hour long. But the hallucinogenic effects of the drug often continue for a full day, and sometimes even longer. Even long after the drug could be detected in a person’s body, they were still able to feel its effects.

To figure it out, scientists used special photographs—called crystallography images—that display how atoms are arranged within a molecule. They zeroed in on images of an LSD molecule inside a serotonin receptor (these receptors are found throughout the brain and body, and create hallucinogenic effects when they attach to LSD). The photos showed that when LSD binds to serotonin, it gets stuck within an inner pocket inside the receptor at such a strong angle that it basically can’t get out. Then the serotonin receptor’s protein structure folds over the LSD molecule, further trapping it in.

Bryan Roth, one of the study’s authors and a pharmacology professor at the University of North Carolina at Chapel Hill, explains little further: The binding technique is likely unique to LSD, as other hallucinogens like psilocybin and DMT (N,N-Dimethyltryptamine) have much shorter effects on the body. Roth and his team plan to use this new knowledge to potentially create novel drugs to treat depression, schizophrenia, and other psychiatric disorders. Drugs used to treat these disorders also work by interacting with serotonin receptors. The idea would be to formulate a drug that gets trapped inside receptors in a similar fashion without causing the same hallucinogenic effects.

Roth says this new understanding of LSD may also help explain the apparent wonders of LSD “microdosing”—where people claim that even tiny, undetectable amounts of the drug provide a tangible effect, boosting creativity and relieving depression (although no evidence-based studies exist to back this up yet). When Roth and his team exposed cells in a petri dish to tiny amounts of LSD, the serotonin receptors’ signaling was altered, meaning that some change was occurring. The researchers plan to further study this effect and what it means.

Roth and his team are targeting multiple receptors to try to develop drugs with this new knowledge, but they’re focusing on schizophrenia first.
