毒品是當今世界上最大的公害之一，毒品對於社會所造成問題及嚴重性，是世界各國所關注的問題；國家發展必須從國民在青少年階段即要向下扎根，青少年是國家發展不可或缺的基石，有鑑於毒品對人類安全的影響，為了人類安全有穩定的發展，減少了在青少年時期就受毒品的危害，國家就能夠富強，而有了研究動機。 近年來新興毒品的興起，青少年施用毒品及校園學生吸毒問題日益嚴重，施用毒品要不要除罪存在著很大的討論空間，而單純施用毒品的行為對他人造成的危害，整體而言是相對來的低，在有限度的除罪化是有其合理性的存在。 本研究以國家安全、青少年施用毒品現象及毒品防制與除罪化作為基礎，研究毒品防制、現行處遇、除罪化是否可行及青少年毒品問題的現象，希望能研究出並找到最適合我國毒品防制的方法。 Drugs are one of the most damange in the world.
