School Shootings in America | Violence and Prescription Drugs

School Shootings

At least 36 school shootings or acts of violence committed at schools have been committed by individuals who were taking or withdrawing from psychiatric medications. In these incidents, at least 250 people were killed or wounded.

While this school shooting statistic is startling, it is also a conservative figure; in numerous mass school shootings, information on medication usage has never been publicized, which means it cannot be confirmed or denied that the perpetrators were under the influence of prescription drugs.

This psychiatric medication link is not limited to school shooters—dozens of acts of senseless violence have been perpetrated by individuals either taking or withdrawing from psychiatric prescription drugs. These tragedies (outside of schools) have killed at least 270 people and wounded at least 164.

Prescription Medications Linked to Violent Behavior

A study conducted by the Institute for Safe Medication Practices found that 31 prescription medications are disproportionately linked to reports of violent behavior. The researchers developed risk ratios for each medication compared to others in the database whilst adjusting for relevant factors that could result in misleading comparisons.

Per the study, the medications below were the most associated with violence adverse events:

  1. Varenicline (Chantix)
  2. Fluoxetine (Prozac)
  3. Paroxetine (Paxil)
  4. Amphetamines (Various)
  5. Mefoquine (Lariam)
  6. Atomoxetine (Strattera)
  7. Triazolam (Halcion)
  8. Fluvoxamine (Luvox)
  9. Venlafaxine (Effexor)
  10. Desvenlafaxine (Pristiq)

List of School Shootings in America With School Shooters on Drugs

School shootings have become ever more commonplace around the world and many of the school shooters responsible for these heinous attacks have been on psychiatric medications, including antidepressants, antipsychotics, ADHD medications, and sedatives all of which have connections to medication-induced violence. The list of school shootings below covers only some of the many high profile incidents with school shooters on drugs.

Date: Feb. 14, 2018
School: Marjory Stoneman Douglas High School (Parkland, FL)
Perpetrator: Nikolas Cruz, 19
Victims: 34 (17 dead, 17 wounded)
Medications: Unknown (ADHD)

It is unclear what medications, if any, Nikolas Cruz was taking at the time he opened fire on students at Marjory Stoneman Douglas High School in Parkland, Florida on Feb. 14, 2018. However, Cruz had previously been diagnosed with depression, autism and attention deficit hyper-activity disorder (ADHD). The link to violence caused by ADHD medication has been documented in medical literature for years.

Cruz was previously identified by the Florida Department of Children and Families (DCF) as a “vulnerable adult due to mental illness” in an investigation. At the time DCF came to this conclusion, Cruz was taking medication for ADHD, per the New York Times. What remains unclear is which ADHD medication he was taking, and whether or not he was taking any other psychiatric prescription medications.
