毒品危害防制條例不再視非法藥物使用為純然犯罪行為，而納入多元處遇模式來處理此問題。本研究以檢察官附命完成戒癮治療緩起訴處分之使用一、二級毒品緩起訴自願受刑人八人為對象，運用實證有效之戒毒處遇理論與模式設計並進行戒癮團體治療，以戒除或降低非法藥物成癮。戒癮團體一週實施一次，每次兩小時，為期十週。二十小時的團體成效顯示成員對團體、團體內容、團體領導者有高度滿意。團體結束時成員的平均壓力感受、行動性衝動與負向自我效能感顯著提升，總體自我效能感顯著降低，壓力感受和準備改變程度有顯著高度正相關，改變階段雖往前進步但未達顯著。本研究分享處遇經驗，並提出討論與團體設計、實務研究、未來政策等方面之建議以為後續方案之參考。

Currently the Narcotics Hazard Prevention Act does not see substance use as a genuine crime, but adopts a multiple-treatment approach to deal with it. _e current study recruited 8 voluntary accused substance addicts who were referred by the prosecutor for deferred prosecution with condition to complete the rehabilitation group treatment. _e group project was designed with related evidenced-based theories and intervention strategies. _e group was done in a fashion of 2 hours for a session, once a week for consecutive ten weeks.

There is significantly positive correlation between perceived stress and readiness to change. The readiness to change is increased at the posttest but not statistically significant. _e group members also show high degree of satisfaction with the group performance. _e implications and further suggestions in terms of group program design, intervention research and related policy were discussed..
