The purpose of this study is to understand problems of the abstention of drug abuse in Taiwan. Comparing the model of Operation Dawn Taiwan with that of the government’s official rehabilitation institutes, this paper aims to identify advantages and disadvantages of the model in private institutes. The opinions of all inmates and tutors in Operation Dawn Taiwan, the biggest private rehabilitation institute in Taiwan, were collected via questionnaires. This study’s findings show that factors of relapse for a drug abuser after leaving rehabilitation institutes include: 1) the enticement from drug fellows; 2) incapability to resist the allure of drugs; 3) unemployment or hindrances to job-finding; 4) psychological depression; and 5) his/her desire for drugs. Inmates and tutors hold the same opinion on all models of the abstention of drug abuse. Specific suggestions of the abstention of drug abuse in Taiwan will also be discussed in this paper. Finally, inmates consider that career planning has significant positive correlations with abstention
