questionnaires from a convenience sample of 1497 high school students in the central district of Jordan.
Results: Students who reported that they have never used stimulant agent were 91.5%, tranquilizer
sedative 87.2%, hypnotic agent 85.8% and antidepressant agent 94.5%, while those never used nicotine
were 81.7%. Coping efficacy (crude OR = 1.07, CI 95% = 1.03 – 1.12), psychological distress
(crude OR = 1.07, CI 95% = 1.03 – 1.11), and perceived social support from family (crude OR =
