A tragic double homicide in Rock Hill, South Carolina, has taken a shocking turn as defense attorneys claim that a psychoactive chocolate bar labeled as “magic mushroom chocolate” impaired the accused shooter. The case is already drawing national attention, raising urgent questions about the safety, legality, and regulation of psychedelic edibles being sold in unregulated markets across the United States.
The accused, whose identity is being withheld pending trial, is charged with killing two individuals at a local smoke shop earlier this month. According to prosecutors, the suspect entered the shop, purchased a chocolate bar labeled as containing “magic mushrooms,” and later carried out the shooting.
During a recent bond hearing, defense attorneys argued that the defendant was under the influence of the psychedelic chocolate at the time of the attack and therefore not fully in control of his actions. They claimed that the bar contained psychoactive compounds that caused unpredictable and dangerous effects. Despite the defense’s arguments, the judge denied bond, citing the severity of the crime and the potential risk to the public.
The defense’s claim that a psychoactive edible was responsible for triggering violent behavior is highly unusual—and legally complex. Psychedelics such as psilocybin are generally not associated with aggression or violent tendencies. In fact, many clinical studies suggest the opposite: psilocybin-assisted therapy has been linked to reduced depression, anxiety, and substance abuse.
However, the defense is capitalizing on the gray market of psychoactive products being sold across the country. Because psilocybin remains a Schedule I controlled substance at the federal level, no psilocybin-containing products should be legally sold in South Carolina or most U.S. states. This raises questions about what was actually in the chocolate bar—and whether undisclosed synthetic compounds could have played a role.
The Rock Hill case is not happening in isolation. Just this week, an Oregon State University study revealed that none of the so-called “magic mushroom edibles” purchased from local smoke shops actually contained psilocybin. Instead, researchers found a cocktail of undisclosed substances, including THC, kava, caffeine, and unregulated synthetic compounds known as “syndelics.”
The finding underscores a troubling trend: consumers often have no idea what they are ingesting when they purchase psychedelic-branded edibles. The Rock Hill chocolate bar may not have contained psilocybin at all, but rather a dangerous mix of stimulants or untested synthetic hallucinogens.
In 2024, the Centers for Disease Control and Prevention documented 180 cases of poisoning tied to mislabeled “magic mushroom” products across 34 states, leading to 73 hospitalizations and 3 deaths. The regulatory vacuum around these products is creating fertile ground for tragedy.
South Carolina law enforcement is treating the chocolate bar as evidence, but without federal oversight, it is unclear how or whether the manufacturer can be held accountable. Unlike cannabis in legalized states, psilocybin products exist in a legal limbo: illegal federally, partially decriminalized in cities like Denver and Oakland, and regulated for therapeutic use only in Oregon and Colorado.
The FDA recently issued a warning against the use of Amanita muscaria mushroom extracts in food products, citing safety concerns, but has not addressed the proliferation of psilocybin-branded edibles. Until lawmakers or regulators act, cases like Rock Hill may become more common.
For advocates of psychedelic-assisted therapy, the Rock Hill case is a nightmare scenario. Just as public perception of psilocybin was beginning to shift—thanks to promising clinical trials for depression, PTSD, and addiction—headlines about violence linked to “magic mushroom chocolate” threaten to derail momentum.
If the defense succeeds in convincing a jury that psychedelic edibles can cause uncontrollable violent behavior, it could stigmatize legitimate therapeutic programs in Oregon, Colorado, and other states considering similar legislation. On the other hand, the case could also accelerate calls for stricter regulation, ensuring that only lab-tested, accurately labeled products are available.
The Rock Hill case is expected to proceed to trial in the coming months. Prosecutors will likely challenge the defense’s claim by pointing to evidence that psychedelics are not inherently linked to aggression, while toxicology reports may reveal whether the chocolate bar contained psilocybin or undisclosed substances.
Regardless of the trial’s outcome, the case highlights a dangerous reality: the U.S. is awash in psychedelic-branded edibles that exist outside of any regulatory framework. Consumers face real risks, and tragedies like Rock Hill may force lawmakers, regulators, and the psychedelic industry itself to confront these dangers head-on.
