　　我國自解嚴後，社會風氣逐漸開放，在暴利與市場供需的情況下，導致毒品迅速在國內漫延，甚至也滲入校園內，政府為了遏止毒品氾濫，除了制定許多防毒策略外，並祭出重刑嚇阻，但毒梟為規避查緝，有朝向刑責較輕的三級毒品來代替傳統海洛因、安非他命等主流毒品之趨勢，因此近3年查獲毒品總數不降反升，此即為主要原因之一。由此可知我國當前毒品防治工作，仍有待精進之處。 本論文係以通訊監察於毒品偵查相關實務運用與法律探討為主軸，首將毒品犯罪概念與罪刑分析，依序探討並提出意見，且鑑於目前毒品嚴重氾濫情形，偵查機關以傳統偵查手段，已無法應付逐漸演變為組織化、科技化、國際化的毒品犯罪，因此，通訊監察儼然成為查緝毒品的利器，然通訊監察係屬一種強制處分，對於憲法所保障的基本權有所干預，在這視人權意識高漲的時代，即便是為了維護社會公益為出發點為之，也是要符合法律規定與其精神原則，如此一來在證據能力得認定上，係屬合法的證據。 因此對於通訊監察相關理論的研究顯得相當重要，故本文以其立法沿革、意義、方式、範圍、程序及違反法律之處罰加以論述。再以我國刑事法規角度、憲法角度、及通訊監察重要原則，檢視我國運用通訊監察結合毒品偵查之相關法制分析。 最後以我國刑訴制度中的證據之定義、種類、證據能力部分及對違法通訊監察之定義、類型、適法性及配合法院實務見解進行探討，另筆者針對目前爭議頗大且常利用於毒品偵查的GPS衛星定位追蹤器之適法性加以分析，及針對通保法制定至今，通訊監察實施過程中所遭遇的窒礙及瓶頸，及通保法修正後，對於毒品犯罪偵查之影響，綜合上述，筆者藉由過去少許的實務經驗，提出相關查緝與修法建議，期能提供修法者與查緝機關一些參考。 關鍵詞：通訊監察、秘密通訊自由、毒品、證據能力、權衡理論、GPS衛星定位追蹤器、

● English Abstract: 

     In our country, the social atmosphere gradually opens after the lifting of martial law. Profiteering and market supply and demand lead to drugs to spread rapidly domestically, and even infiltrates into the campus. In order to curb the spread of drugs, authority institutes a number of anti-drug strategies, and resorts to severe punishment. However, to avoid being arrested, drug lords tend to replace mainstream drugs such as traditional heroin and amphetamines with third-tier heroin for less severe punishment .That’s why, for the past three years the total amount of drug caught up rise, not fall. Therefore, for current drug prevention work there remains rooms to be improved. This thesis focuses on how the technique of communications surveillance can be used as the practical way to investigate drug crimes and how the practice should be viewed from the aspects of law. First of all, the author discusses and comments on the concept of drug-related crimes and the analysis of crime in order. In view of the current drug abuse, the investigating authorities with traditional investigative techniques have been unable to cope with international drug crime syndicates possessed with evolving systematization and technology. Therefore, communications surveillance has become a tool to detect drugs. However, communications surveillance belongs to a mandatory punishment, which contradicts the fundamental rights for civilians guaranteed under the Constitution. In this age with high awareness of human rights, even the activity based upon the protection of public welfare also needs to comply with the law. In this way, the credibility is proved. Therefore, the research on the theory of communications surveillance becomes very important. This thesis explores its legislative history, significance, methods, scope, procedures and penalties for the violation of the law. Furthermore, from the angles of criminal statutes and Constitution, the important principles on communications surveillance, the author examines related rules in which communications surveillance is applied into drugs Investigation. Finally, within Criminal Procedure System, the following shall be explored: the definitions on evidence, types, credibility and the illegal surveillance of communications, type, and the proper method of practice with the Court. In addition, the author analyze the credibility for the controversial usage of GPS satellite positioning tracker in drug investigation; the bottlenecks encountered in processing drug investigation after the establishment of Communications Security and Surveillance Law so far; and the impact upon which communications surveillance inflicts drug investigation . In summary, through little practical experience from the past, the author makes suggestions about related arrest and amending relevant laws, so that laws amender and investigative authority can make use of them as reference. Key words: communications surveillance, secret communications freedom, drugs, credibility, GPS satellite positioning tracker,
