Psychedelic drugs are known to make people highly sensitive to their surroundings. In other words, a user's mindset and immediate environment heavily shape the entire trippy experience. In a study published in the journal Psychedelic Medicine, scientists wanted to test a brand-new idea: whether an invisible backdrop of national culture, rather than just a person's local setting, could influence people's support for partisan violence after taking a psychedelic.
Their real-world test bed focused on timing trips around Fourth of July celebrations and other major politically significant events.
The research was motivated by the rise of political violence in the U.S., with increasing numbers of people believing that force is a justified way to advance certain political goals. Because psychedelics are known to make people highly suggestible, researchers wanted to find out if these substances act like a magnifying glass for whatever mood or message is already in the air.
Tracking trips around political events
The research team recruited nearly 22,000 U.S. adults and surveyed them twice. The first questionnaire was designed to measure baseline views on political violence, and the second was given about two months later. The participants did not know that the research was specifically about drugs.
Around 12,000 people completed the second survey, and of those, 505 reported using classic psychedelics like LSD or magic mushrooms during the study window. The researchers then asked these people for the exact dates of their most intense trips so they could match them with major events on the political calendar.
The results revealed that participants who had their most intense psychedelic experience on the Fourth of July showed a larger drop in support for partisan violence than those whose most intense experiences occurred on other days. The analysis also suggested that people who took psychedelics during Democratic or Republican conventions or closer to Election Day showed an increase in support for partisan violence.
"The results suggest that naturalistic psychedelic use on the Fourth of July and other dates of politically salient events may modulate support for partisan violence in directions that depend on the political nature of the events," the study authors wrote in their paper.
The Trump exception
However, there was one exception: around the first Trump assassination attempt. Participants whose most intense psychedelic experience occurred on that date showed a decrease in support for partisan violence, and this effect was seen only among Republican users.
The researchers suggest this may have been because the event triggered widespread shock and reduced support for violence among Republicans at the time. They propose that, for people tripping then, the psychedelic experience may have amplified that broader social mood.
Study limitations
While this research is the first time an observational study has backed up what was previously only a theory—namely, that the national mood can color a psychedelic trip—it is worth noting its limitations.
Only 19 people actually tripped on the Fourth of July, and nearly 44% of the participants did not return the second survey. Also, because this was an observational study rather than a laboratory experiment, it can show only an association, not prove that psychedelic use caused these shifts in attitudes.
Nonetheless, the paper offers a new way to look at how psychedelics and society mix, as the researchers note. "It appears the broader sociocultural context could influence outcomes following naturalistic psychedelic use."
