A man who transfers narcotics, which also belong to prohibited drugs, will be punished by the court with the Pharmaceutical Affairs Act rather than the Narcotics Hazard Prevention Act, which has lighter punishment. But if the offender in accordance with article 17 of the Narcotics Hazard Prevention Act, confessed the source of drugs or made his confession during the investigation and trial, this paper would like to discuss whether this situation has any possibility to be eligible for reduced penalties. In practice, according to the overall principles of law applicable, the court will not lacerate the application of the Act of Pharmaceutical Affairs and the Narcotics Hazard Prevention Act. This paper thinks that the practice always has the distinction in the reduction and aggravation provisions between general principle and specifics of the criminal law, however it isn’t detailed discussed here.In the specific provisions of criminal law, the reduction and aggravation provisions have become the new illegal constitutive requirements. Thus, they shall not be applied separately. The Narcotics Hazard Prevention Act’s reduction regulation mentioned above, nevertheless, is one of the reduction regulations in the general principle of the criminal law, and that shall not cause any doubt in lacerating the application of regulations. So, in the author’s opinion, in accordance with the custom of the special law complemented by the general law, the court shall apply the Act of Pharmaceutical Affairs and the Narcotics Hazard Prevention Act altogether in the penalty.
