Substance; Use; Chat; Alcohol


The world drug problem continues to constitute a serious threat to public health and to the safety and well-being of humanity-particularly children, young people and their families [1]. About 230 million people or 5 percent of the world’s adult population are estimated to have used an illegal drug at least once in 2010. Alcohol and other drug (Khat and tobacco) users number about 27 million, which is 0.6 percent of the world adult population [2].

The United Nations Office on Drugs and Crime reports while drug use is stabilizing in industrialized countries, it is increasing in developing nations [3]. In Ethiopia a national study reported 23.0% of out-of-school and 7.5% of in-school adolescents use khat [4]. A separate study estimated prevalence of khat use in the general population of Ethiopia was 27.3% among men and 11.0% among women of 15-49 years in 2011 [5]. Heavy consumption of khat is associated with euphoria, hyper activity, anorexia, insomnia, lethargy and depression. In addition to combined use of alcohol and khat could increase sexual risk behavior contributing to spread of HIV [6,7].

In Ethiopia there is research evidence that indicate substance abuse is also increasing among high school and university student [8]. Substance use remains as an important area of research due to the implications of early substance dependence on the future of the youth [9].

Mizan Aman town is one of developing urban center and becoming educational hub of the country, it is expecting that the increasing trend of substance abuse among school student might be similar for our study area. Knowing the current magnitude of substance abuse have importance for future anti substance use behavioral change program, thus this study was conducted with the aim of assessing magnitude of substance abuse among students Aman Poly Technique College, South west Ethiopia.


Study setting and design

A descriptive quantitative cross sectional study design was conducted among students of Aman Poly Technique College.

Aman Poly Technique College is found at Mizan-Aman town of Benchi Maji zone of Southern nation nationalities and peoples of Ethiopia regional state (SNNPR) which is located 561 km from Addis Ababa; 234 from Jimma and 4.5 km from Mizan town. Aman TVET Collage was established in 1994 E.c and started its work in the same year by four departments with the total number of less than two hundred students. Currently the college has 885 students, studying 8 fields of technique and vocational education with different level; Level I, Level II and Level III.

Study participants

Regular students of Aman TVET College in Aman town obtained by sampling during the specified study period were included in the study.

Sample size and sapling

The formula that we were used to calculate sample size in the study was single population proportion formula. Prevalence of point under consideration was (P=50% because to the extent of our knowledge and searching effort, no P value has been obtained about the magnitude of substance abuse in the study area). So the 384 sample size was computed and after using correction formula hence our total population is less than 10,000 the final sample size became 268.

We were used stratified random sampling method followed by simple random technique to select individual students that are to be included in our sample size. Using stratified random sampling method, the total numbers of students in the college were first divided into different strata based on their departments and level of study. Sample was allocated to each departments and level of study proportionally. Finally, simple random lottery method was used to select study participants using sampling frame of students list (Table 1).
