本研究的主要目的在了解臺北市國中學生對藥物濫用的知識、態度及用藥行為現況，並以學生的社會入口學、學業投入、同儕用藥狀況及態度、家庭因素，來預測學生對藥物濫用的知識、態度及用藥行為。
研究對象為民國八十二年十二月份在學之臺北市公私立國中普通班的學生（不含特殊班級及補校），以比率機率抽樣法抽出661人為樣本。研究工具採結構式問卷調查法，問卷內容包括個人基本資料、藥物濫用知識、藥物濫用態度及藥物濫用行為四部份。資料收集以團體自填問卷的方式施測，共獲得有效問卷640份。
研究結果發現學生藥物濫用知識測驗的答對率為75.7％ ，在藥物濫用的基本概念、生理、心理、社會層面四部份中，以藥物濫用的心理層面（89.57％）答對率最高，其餘依次為藥物濫用的社會層面（79.14％）、藥物的基本概念（72.50％）、藥物濫用的生理層面（69.30％）。學生獲得藥物濫用知識的來源，以電視最多，其次為報紙、老師，再其次為海報、父母、雜誌或期刊、醫護人員。
受測學生對藥物濫用的態度方面，總分平均值為5.37分，顯示總體而言，學生大部分不贊成使用成癮性藥物。在學生吸菸、飲酒及使用成癮性藥物方面，以曾經飲酒最多（76.4％），其次為曾經吸菸（31.6％），而曾經使用成癮性藥物者最少（0.6％）。
探討受測學生的藥物濫用知識與藥物濫用態度的相關，發現此二者間有中度的正相關（r=.39，P<.001），顯示學生的藥物濫用知識得分愈高，則其愈不贊成使用成癮性藥物。
受測學生的社會人口學、學業投入、同儕用藥狀況及態度、家庭因素中的14個變項，能顯著預測學生對藥物濫用的知識（R=.30，F=4.14，ｐ<.001），能夠解釋知識總變異量的6.8%，其中取有影響力的變項是「學業成績」，能解秋總變異量的4.3%；其次是「年級」，可再增加0.8%的解釋力。
受測學生的14個預測變項，能顯著預測其對藥物濫用的態度（R=.37，F=6.65，P<.001），能解釋態度總變異量的11.5%。其中最有影響力的變項是「同儕對有藥的態度」，能解釋總變異量的7.4%；其次是「學業成績」，可再增加2.3%的解釋力；再其次是「性別」及「同儕用藥狀況」，可分別再增加1.0%及0.9%的解釋力。
本研究建議教育機關應制定一套完整的藥物教育計劃，並在各級學校中進行研究。另外，在設計藥物教育課程時應加強濫用藥物對生是的危害及其明確的刑罰。而在未來的研究上，再增加樣本的人數、增強自變項及再佐以觀察、驗尿、深度訪談等方法收集資料，可使研究更完善。

The main purpose of this study was to research the knowledge, attitude and behavior of drug abuse among junior high school students in Taipei City In addition, we also to predict these results by their demography, achievement in school, peer drug abuse and attitude, and family factors.
The sample was selected by the proportionate probability sampling method. Six schools were included, with the total number of valid question-naires being 640. The data were collected via a group self-administration in December 1993.
The main findings of this study were as followings:
1. The correct rate in the test about knowledge was 75.5%.
2. The most common sourceuof knowledge was the televesion programs which was followed by newspapers and teachers.
3. The mean scoring about the attitude of drug abuse was 5.37 which revealed that most of students disapproved to use addivtive drugs.
4. The rate of students who has been taken addictive drug was 0.6%
5. There was a positive relationship between knowledge and attitude about the drug abuse. (r=.39，P<.001). The result showed that the higher the score about knowledge, the less they agreed to use addictive drug.
6. We could predict the knowledge and attitude of the students via their demography, achievement in school, peer drug abuse and peer attitude, and family factor.
7. The predictive rate for knowledge was 6.8%; for attitude was 11.5%.
We suggested the authority of education to set a good program for drug education and start experimental study inevery school. We also have to emphasize the dangerous of the addictive drug to phisical body and calrify the punishment of abuse in these programs.
Furture research need more samples, indepednt variables and fruther clinical observation, urianalysis and sincerly talking to make the study more perfect.
