Detailed description: 
      This study aims to measure the effects of a per-led educational intervention based on theory
      of planned behavior to reduce tobacco, alcohol and khat use and intention to use among
      secondary school students over 3-months of follow-up in Dessie and Kombolcha town, Northeast
      Ethiopia.A quasi-experimental nonequivalent control group pretest-post-test design will be
      carried out among secondary school students of Dessie and Kombolcha Town from April to
      August, 2021. Individuals/Students/ in those selected schools will be allocated as
      intervention and control group purposively. The study will include 748 students from two
      secondary schools for the intervention group and another 748 students for the control group
      from other two secondary schools. The per-educational intervention will be planned based on
      results of the elicitation and TPB constructs and will be implemented on the experimental
      group for three months. Both experimental and control groups will be followed up after three
      months of educational intervention using the same tools and methods on same participants
      interviewed in pretest survey. Primary outcomes are substance(Cigarette,alcohol and Khat) use
      intention and behavior. Secondary outcome are attitudes, subjective norms, and perceived
      behavioral control over substance(Cigarette,alcohol and Khat) use. Self-administered
      questionnaire based on TPB constructs will be used to collect the baseline and follow up
      data. In-depth interviews will be employed to explore the salient beliefs about substance
      use. The data will be analyzed using SPSS statistical software package version 20 using
      appropriate statistical tests including paired t-test, independent t-tests, McNemar and
      multivariate logistic regression analysis. All statistical tests will be carried out using
      two tailed tests with alpha set at 0.05. Information from the interviews will be transcribed
