The Overcoming Cohort study is a studies looking for variations in DNA,for populations less than or 25 years of age, that either protect people from COVID-19 disease or make them more susceptible. The study will sequence patients' entire genome or the smaller group of genes that code for proteins (exome). The study would gain a better understanding of COVID-19 that would improve diagnostic, prevention, and treatment measures.

The study will test a computerized treatment with subjects ages 13-17 years who are interested in seeking treatment for alcohol and/or cannabis use. Follow-up assessments will be conducted at one- and three-months following treatment.
