Received 11 May, 2020; Accepted 16 June, 2020 It is customarily challenging and fruitless to prevent young adults and teens from drug experimentation. Yet, the onset of marijuana or cannabis use by school-age young adults and teens could be delayed with holistic interventions that aim at involving stakeholders (that is schools, families, agencies, media, etc.). The objective of this review was to sum-up continental comparative data on the prevalence of cannabis or marijuana use among young adults. Although continental studies on the prevalence, causes, effects, and preventions of marijuana use are limited, there is evidence to suggest that marijuana use is still on the rise among young people globally, especially in Africa, Europe, and America. False gratification such as, its harmless effects, its ability to aid performance, and its ability to protect one against superstitious forces are factors among others that lead adolescents to its experimentation. Key words: Adolescents, marijuana, cannabis, prevalence.

For this review, systematic cannabis among aged 15-24 years to range from 44.2 to evidences were examined across multiple national and 4.6% in 2016. On country basis, France 44.2%, the individual studies such as The UNODC World Drug Czech Republic 39.2%, and the Netherlands 31.5% were Report (2018; 2019), EMCDDA European drug report countries with a higher lifetime cannabis prevalence (2018), Drug Statistical Bulletin (2019), ESPAD Group among the fore mentioned age group in 2016, while low Report (2016), Australian Criminal intelligence rates were reported in Romania 8.9% and Portugal commission report on illicit drugs (2017-2018), CICAD 13.2%. report on drug use (2019), etc. to make conclusions on However, on past month usage, an estimated 7% the trends and prevalence. adolescents aged 15-16 years were reported to have The predefined theme to search for relevant studies on used cannabis in the past month with France 17% and the topic started generally with “cannabis/marijuana and Italy 15% among the highest in their 15–16 year olds; adolescents, prevalence across the world” and ended while lower figures were reported in Sweden and Finland with a more focus on continental findings.
