Abstract

Abstract: Objective: To report results from a follow-up study of alcohol, cannabis and other drugs on suicidal behavior. Method: We estimated prospective associations of substance use as a risk factor for incident suicide ideation and attempt, from a follow-up conducted in 2013 (n = 1071) of the original Mexican Adolescent Mental Health Survey conducted in 2005. Results: Cannabis use before age 15 (ideation risk ratio (RR) = 3.97; 95% confidence interval (CI) = 1.43–11.03; attempt RR = 5.23; 95% CI = 1.17–23.32), early onset of DSM-IV drug use disorder (DUD) among cannabis users (ideation RR = 3.30; 95% CI = 1.11–9.84; attempt RR = 4.14; 95% CI = 1.28–13.36), high frequency of cannabis use (RR for attempts = 4.60; 1.03–20.60) and recent DSM-IV-DUD among cannabis users (RR for attempts = 4.74; 1.09–20.57) increased the RR. For "other drug use", significant results were found among those with high frequency use of other drugs such that they had a higher RR of suicide attempt (5.04; 1.03–24.64). For alcohol, only those who initiated alcohol before age 15 had higher RRs of suicide attempt (1.79; 1.00–3.20). Discussion: Those who used cannabis at an early age, early onset of DSM-IV-DUD, and those with heavy cannabis use and recent DSM-IV-DUD among cannabis users in the last 12-months had increased risk of suicide ideation and attempt. Drugs other than cannabis showed some of these associations, but to a lesser degree. Prevention of substance use and treatment of those already engaged in drug use, by decreasing suicide ideation and attempt, may help to prevent suicide in Mexico.
