Seventeen-year-old Connor Hilton was charged with murder and aggravated assault in September of 2025 after shooting two of his friends. Hilton reported having suicidal and homicidal ideations prior to the offense due to the medical side effects of the acne medication Accutane, according to the New York Times. The defense team argued that the psychotic episodes Hilton was experiencing were due to the known side effects of the acne medication, stating that when Hilton was not taking the medication, these episodes did not occur. The case ended in a guilty verdict, as the judge ruled that the medical side effects of Accutane were not admissible as evidence of Hilton’s proclaimed involuntary actions during the criminal event.
The use of medical side effects as a mitigating factor in criminal cases has legal scholars at a standstill in research, reported by Greg Hill & Associates. According to the U.S. Pharmacist, there is an abundance of nonpsychotic medications that can lead to medication-induced psychosis, resulting in emergency department visits, hospitalization and death. Individuals affected by medication-induced psychosis often endure paranoid ideations, hallucinations and confusion, all of which are significantly associated with an increased risk of criminal activity and violent behaviors, as stated by the National Library of Medicine.
Despite the possibility of medications producing intense psychological distress, judges rarely accept medical side effects as a factor that should be considered when analyzing a defendant’s guilt. Mental health and substance abuse are factors more commonly considered during deliberation as elements that may have contributed to the crime noted by John Anthony Picerno. The growing acceptance of mental health conditions in accordance with criminal activity has given rise to the use of mitigation evaluations. In the words of Vorwerk Forensic Psychology, Inc., during these evaluations, the defendant is subjected to a comprehensive psychological assessment to analyze the influence their medical history has on the actions used to commit the crime. These exams have proven beneficial in cases where difficulties with medication-induced cognitive impairment are present. According to the National Institute of Health, this phenomenon consists of a reversible decline in mental functions, often resulting in situations where an individual experiences psychosis-like symptoms, leading to criminal activity. An increasing number of cases using this medical event as a mitigating factor in the motivation for participating in such a crime are beginning to emerge alongside the fast-paced medicalization of the world. The setback in the matter, however, is the continuing reluctance of court officials to recognize and accept temporary psychosis as a factor that sets an individual’s behavior apart from their normal routine. As of present, there has been no single case where the courts have accepted the excuse of prescription medication side effects as a successful legal excuse, as clarified by CBS News. The case of Connor Hilton gained widespread media coverage as the defense team adhered to the rarely cited medication-induced psychosis plea in hopes of highlighting Hilton’s significant change in behavior during his Accutane treatment timeline. According to the Centers for Disease Control and Prevention, prescription medication usage worldwide has grown approximately 14% in the past five years and is projected to continue exponentially by the year 2028. With the expanding need for prescription medication, a nuanced way of thinking about the direct implications that medical side effects have on an individual’s psyche, may need to be evaluated
In cases similar to Connor Hilton’s, the legal system is challenged with a complex question of how to balance the intersection of psychology, law and medicine. Medication-induced psychosis is a medically recognized occurrence and the justice system has yet to determine how cognitive implications may interfere with criminal responsibility. With the increased globalization of medication usage, courts will likely face similar cases at an increasing frequency. Constructing clear legal standards and investing in collaboration between medical and legal experts may be a requirement to ensure criminal responsibility is evaluated with growing scientific understanding and fairness under the law.
