Dual Diagnosis and Suicide Probability in Poly-Drug Users

To determine the frequency of suicidal thoughts and suicidal probability among poly-substance abusers in Saudi population, and to examine the relation between dual diagnosis and suicidal thoughts.

Case control study.

Al-Baha Psychiatric Hospital, Saudi Arabia, from May 2011 to June 2012.

Participants were 239 subjects, aged 18 - 45 years. We reviewed 122 individuals who fulfilled the DSM-IV-TR criteria of substance abuse for two or more substances, and their data were compared with that collected from 117 control persons.

Suicidal cases were highly present among poly-substance abusers 64.75%. Amphetamine and cannabis were the most abused substances, (87.7% and 70.49%, respectively). Astatistically significant association with suicidality was found with longer duration of substance abuse (p < 0.001), using alcohol (p=0.001), amphetamine (p=0.007), volatile substances (p=0.034), presence of comorbid psychiatric disorders (dual diagnosis) as substance induced mood disorder (p=0.001), schizo-affective disorder (p=0.017), major depressive disorders (p=0.001), antisocial (p=0.016) and borderline (p=0.005) personality disorder. Suicidal cases showed significant higher scores (p < 0.001) of suicide probability scale and higher scores in Beck depressive inventory (p < 0.001).

Abusing certain substances for long duration, in addition to comorbid psychiatric disorders especially with disturbed-mood element, may trigger suicidal thoughts in poly-substance abusers. Depression and suicide probability is common consequences of substance abuse.
