Its objectives were to reveal the unfriendly consequences of certain social media activities on the health of young people and how such activities can propel risky behaviours among them.

Social media in the paper was defined as those internet-based social websites or social network sites such as Face book, WhatsApp, 2go, Instagram, Twitter, Baidu Tieba, Pinterest, LinkedIn, YouTube, that serve as instrument for interaction between person to person, or group of persons. Extensive highlights and discussions on the consequences of the use and abuse of online social activities of young persons were addressed.

Other consequences of social media abuse as discussed in the paper were cyber bullying, sexual promiscuity, exposure to ritualists and death. In order to reduce the negative effect of this social problem on young people, the paper recommended among others that the Ministry of Education (Federal and State) must as a matter of urgency add to their curricular –Social media education for both the primary and secondary schools.
