The purpose of the study was to analyze the historical patterns in the relationship between specific types of disabilities and frequency of drug abuse or weapon offenses in public schools in the United States using the U.S. Department of Education Open Data Platform's (n.d.) data sets from 2011-2012 through 2020-2021. The problem is that students with disabilities are involved in drug abuse and weapon offense incidents in public schools at alarming rates. Theoretically, the historical pattern of students with disabilities abusing substances and committing weapon offenses from the 2011-2012 through 2020-2021 school years would reveal that some disabilities were more prone to using weapons and abusing substances. In my research, I examined the historical pattern in the relationship between type of disability and frequency of drug abuse and weapon offenses using six disability categories. Foster (2015) found that students with emotional disturbance had a higher rate of drug abuse and weapon offenses compared to other students with disabilities, followed by students with specific learning disabilities, traumatic brain injury, and intellectual disability. The researcher expected to find results similar to Dr. Foster's findings. Foster did not include students with other health impairment and autism, who may have high rates of weapon offenses and drug abuse. The second part of this study reviewed studies about the effectiveness of the intervention, prevention, and treatment programs for students with disabilities in public schools that focus on reducing engagement of students with disabilities in substance and drug abuse and weapon offenses. The concept of executive functioning and the deficits in social skills and problem solving in different disabilities was examined to investigate relationships between the decision-making process and involvement in drug abuse or weapon offenses.
