07/18/13 | Effects of State Medical Marijuana Laws on Adolescent Marijuana Use
Researchers at the Institute for Child Health Policy at the University of Florida College of Medicine examined what effect, if any, medical marijuana laws have on teen use. U.S. anti-drug officials like the drug czar have said such laws decrease the perception of risk and therefore lead to an increase in teen use. Looking at data from 2003-2011 from Montana, Rhode Island, Michigan, and Delaware, these researchers found "no discernible pattern suggesting an effect on either self-reported prevalence or frequency of marijuana use." They conclude that passage of medical marijuana laws does not measurably affect adolescent marijuana use.
04/26/13 | Do medical marijuana laws increase marijuana use? Replication study and extension.
Replicating a prior study, but controlling for state characteristics and measurement error, researchers found that medical marijuana laws have little discernible impact on teen marijuana use or perceptions of the risk of marijuana use in those states. In fact, their research showed that passage of medical marijuana laws actually resulted in a slight decrease in teen marijuana use.
07/13/12 | Exploring the Ecological Association between Crime and Medical Marijuana Dispensaries
Applying the "routine activities theory" of crime, this NIDA-funded study used data from 95 census tracts in Sacramento to analyze two types of crime (violent and property) in areas with varying concentrations of dispensaries. Results indicated that while factors traditionally understood to lead to increased crime ��� large percentages of land zoned for commercial rather than residential use, a high percentage of one-person households, the presence of highway ramps, a higher percentage of the population being ages 15-24 ��� were positively associated with crime in those areas, the density of medical marijuana dispensaries was not associated with violent or property crime rates. In their conclusion, the researchers theorize that measures dispensaries take to reduce crime (i.e., doormen, video cameras) may increase guardianship, thus deterring crime.
07/13/12 | Chemopreventive effect of the non-psychotropic phytocannabinoid cannabidiol on experimental colon cancer
This analysis of the anti-cancer properties of cannabidiol, a non-psychoactive constituent of marijuana, studied its effect on mice and found that it reduced polyps, tumors, and other carcinogenic precursors, and in colorectal carcinoma cell lines, "protected DNA from oxidative damage, increased endocannabinoid levels and reduced cell proliferation," leading the authors to conclude that cannabidiol does exert a chemopreventive effect.
07/13/12 | Cannabinergic Pain Medicine: A Concise Clinical Primer and Survey of Randomized-controlled Trial Results
This meta-analysis of 38 other randomized-controlled trials that studied the use of cannabis based treatments found that, of these, 27 (71%) "concluded that cannabinoids had empirically demonstrable and statistically significant pain-relieving effects" while 11 (29%) did not.
07/13/12 | Cannabidiol enhances anandamide signaling and alleviates psychotic symptoms of schizophrenia
This double-blind, randomized trial compared the effects of cannabidiol, a non-psychoactive constituent of marijuana, to amisulpride, a potent antipsychotic, in treatment of acute schizophrenia. Results showed that both treatments were safe and effective, but treatment by cannabidiol involved a much safer side-effect profile and presented greater evidence of long-term clinical improvement.
07/13/12 | Smoked cannabis for spasticity in multiple sclerosis: a randomized, placebo-controlled trial
This placebo-controlled, crossover study on the effects of smoked marijuana on spasticity, a common and difficult to treat symptom of multiple sclerosis, found that marijuana was significantly more effective than placebo at both reducing muscle spasticity and patients' pain sensations.
