“…At the federal level, the Obama Administration has instructed prosecutors and law enforcement officials not to focus on individuals "whose actions are unclear and unambiguous compliance with existing state laws providing for the medical use of medical marijuana". Thus, the shift in federal position prompted a drastic increase in registration for medical marijuana, particularly in Colorado [40][41][42][43][44].…”

Marijuana is a substance that has been used for recreational purposes since ancient years and that is currently discussed to have a therapeutic or medical value and to be seen as a Medicine.According to the FDA, marijuana is classified as a Schedule I drug with high risk of addiction and no medical benefit. However, it is legal in several states for deliberating conditions e.g. various pain conditions, depression, anxiety, nail patella, glaucoma and even HIV.In addition people use is for various other conditions even though studies have shown greater harmful effects then benefit. Especially with marijuana, there is a high rate of misperception in the users. In addition, marijuana has a unique pharmacology and pharmacodynamics because of its more than 400 partially unknown components and the storage in the user's lipophilic tissues and redistribution long after the last use.The legalization of marijuana is already done in some states and other states are pressured to follow along.This article is a systematic review of literature analyzing the current policies, legal situations and trend as well as politics regarding marijuana and its use. The article is focused on the natural form of the Cannabis sativa plant.

“…For MMLs in particular, Maryland (MD) is an interesting state in this respect. A law was passed in MD providing an affirmative defense for patients, physicians, and caregivers ; however, the law is very restrictive, so some authors conclude that MD does have a MML (Pacula et al 2015;Lynne-Landsman et al 2013) and other authors conclude that MD does not (Anderson et al 2015;Wen et al 2015;Harper et al 2012). Since there are delays between when a law is passed, when it is made effective, and when it is implemented on the ground, researchers need to be careful to identify the relevant date of interest for the units in the treatment group.…”

Evaluations of the impact of medical and recreational marijuana laws rely on quasi- or natural experiments in which researchers exploit changes in the law and attempt to determine the impact of these changes on outcomes. This chapter reviews three key issues of causal inference in observational studies with respect to estimating of impact of medical or recreational laws on marijuana use-intervention definition, outcome measurement, and random assignment of study participants. We show that studies tend to use the same statistical approach (differences-in-differences) and yet find differential impacts of medical marijuana laws on adult use in particular. We demonstrate that these seemingly conflicting findings may be due to different years of analysis, ages of the study sample in each year, and assignment of jurisdictions to the control group versus treatment group.

“…Although the epidemiologic data are not consistent across states and time periods, with the exception of Michigan and New Mexico, in all states where medical marijuana has been legalized, marijuana use by minors has been stable or has decreased. 3 Youth substance use rates depend on a number of factors, including legal status, availability and ease of access of the substance, and perception of harm. For example, although tobacco is easily accessible, youth tobacco use rates have decreased substantially since the 1990s, in conjunction with aggressive public health campaigns warning of the medical consequences of smoking.…”

This policy statement is an update of the American Academy of Pediatrics policy statement “Legalization of Marijuana: Potential Impact on Youth,” published in 2004. Pediatricians have special expertise in the care of children and adolescents and may be called on to advise legislators about the potential impact of changes in the legal status of marijuana on adolescents. Parents also may look to pediatricians for advice as they consider whether to support state-level initiatives that propose to legalize the use of marijuana for medical and nonmedical purposes or to decriminalize the possession of small amounts of marijuana. This policy statement provides the position of the American Academy of Pediatrics on the issue of marijuana legalization. The accompanying technical report reviews what is currently known about the relationships of marijuana use with health and the developing brain and the legal status of marijuana and adolescents’ use of marijuana to better understand how change in legal status might influence the degree of marijuana use by adolescents in the future.

Effects of State Medical Marijuana Laws on Adolescent Marijuana Use

Abstract: Our results suggest that, in the states assessed here, MMLs have not measurably affected adolescent marijuana use in the first few years after their enactment. Longer-term results, after MMLs are more fully implemented, might be different.
