Most of the people in United States are abusing Marijuana excessively. An active chemical is present in marijuana, called delta 9 tetrahydrocannabinol ( THC). It can be taken orally, mixed with food, and smoked in a concentrated form as hashish.
According to the survey conducted by the Monitoring The Future (MFT) which is sponsored by the National Institute For Drug Abuse, there is a decrease in the use of marijuana among the 8th, 10th and 12th graders through 2006, 2007, and 2008. After this there has been an upturn in use in all three grades. In 2010, there was a significant increase in daily use in all three grades, reaching 1.2%, 3.3%, and 6.1% respectively. Perceived risk increased in all grades through 2004 as use decreased. Perceived risk fell after 2004 and 2005 in 12th and 8th grades respectively, presaging the more recent increase in use. From 2003 to 2007, disapproval increased in all three grades, but has been in decline since then as use of the marijuana increased.
According to the MTF reports, 41% of 8th graders, 69% of 10th graders, and 82% of 12th graders said that it is fairly or very easy to get to get the marijuana in 2010. Marijuana is less accessible to young adolescents. Thus from the reports it is clear that marijuana has remained a highly accessible drug.
