There are number of drugs being abused in the society currently, cannabis sativa, also marijuana being among the most abused drug. There is a strong scientific support concluding that cannabis sativa has high potential abuse and addiction. Diagnostic guidelines by both The International Classification of Disease [ICD] and the Diagnostic and Statistical Manual of Mental Disorders [DSM] have designated that cannabis sativa is addictive and currently recognize cannabis related dependence disorders.
By 2014, cannabis sativa had the highest rate of use, with the cohort of 20-29 year olds consuming the most. In 2013,it was estimated that about 6.6 million[10.25%] had used cannabis sativa in the previous 12 months. About one in 20 Australians [5.3%] had used cannabis sativa in the month prior to the survey and 3.5% had used in the previous week.
Among people aged 14-24, the age at which they abused cannabis sativa had increased between 2010 and 2013, cannabis users were more likely to try cannabis at their teens. The age of first use was younger compared to other illicit drugs. One third [32%] of recent cannabis users used it as often as weekly.
One fifth of recent cannabis sativa users stated all or most of their friends currently used the drug in contrast to only 0.8% of those who had never used cannabis. In parallel with the US, between 2010 and 2013, the proportion of people aged 59-60 or older using cannabis rose [from 5.5% to 7.3% and from 0.5% to 1.2%, respectively], which is the highest levels seen over the past decades, this may reflect an aging cohort of cannabis users.
According to [Bell, Wechsler &Johnson, 2007] approximately 25% of college students have used marijuana within their past years. Ultimately, with one fourth of college students using marijuana.
For more than a decade, researchers have commonly noted a steady increase in marijuana use among college students. Researchers completing a longitudinal study segregated marijuana users into two groups, past
30-day and past year’s users. The percentage of 30-day marijuana users increased from 13% in 2003 to 17% in 2007 while, the past- years marijuana users rose from 23% in 2003 to 30% in 2007.Report from [The Higher Education Centre for Alcohol and Other Drug Abuse and Violence prevention, 2008]
College can be a time where parental surveillance is at an all-time low and where young adults experiment with high risk behaviour before having to face the responsibilities in adulthood. About 33% of college students on marijuana reported that they first experimented wit he substance when they were 18 or older.[Gledhill-hyot,lee,storte,&Wechsler,2006] .
One study focused on cannabis use with first year college students and found that marijuana use was the highest in freshman year in college and progressively declines with each following year but an increase at the end of the academic year proving that when weather is of warmer temperatures and enforcement is not as intense, it becomes an ideal time for colleges to use [Dierker et al, 2000]
The most recent study at University of Maryland college park focused on marijuana use with first year college students found that one in ten incoming freshman were considered, by clinical definition, to have cannabis use disorder. Another concern, among the students who had used marijuana five times or more over time,[40.1] reported concentration problems, regularly putting themselves in danger,[24.3%],driving under marijuana influence,[18.6%] and oversleeping hence missing classes at[14%](caldeira et al.2008).
According to Monitoring Future Report [Johnstone,O Malley,Bachman,&schulenberng,2006,2008]indicated that 37% college students had used illicit drugs,28% of the cases being marijuana.
