Youths are considered to be an important segment of the society because largely they are regarded as the most productive part of every nation. To attain level of development; societies should properly and adequately orient and socialize their youths so that they conform to the societal positive recommendations and ultimately got integrated into the main developmental society process. One of the means by which youths are properly and adequately oriented and socialized is addressing the issues in youth biological, physical, mental and moral health. To achieve this, positive youth culture has to be sustained, and one of the means of sustaining positive youth culture is Drug Education. Therefore, this paper focuses on the role of drug education in sustaining positive youth culture as a necessary requirement for adult education and community development in Nigeria. Descriptive method was employed, reviewing the relevant literature on the theme of the paper. The paper, among others, found that drug education helps people to develop lifestyle conducive to healthy living, recognise the inimical and devastating effects of substances (drugs) of abuse to the physical, mental and social well- being of a person. The paper therefore recommends among others, that drug education should be in all of the curricula of our schools, promoted and given the proper and commensurate attention and consideration by all those concerned; particularly the government, ministry of education and the society as a whole. This will go a long way in sustaining positive youth culture as an important phenomenon in adult life and community development.
