Dispensary denseness
former research has shown that , in areas where alcohol is promptly available at hard drink stores and bar , there are higher rates of local fierceness , hitch and alcohol - relatedhospitalizations , Mair articulate . She and her colleagues decide to put marijuana dispensaries to the same tryout , set whether they were associated with more all-night hospital stays related to lot utilisation .
Mair read she and her workfellow opt to learn California because of its farseeing history withmedical marijuana — in 1996 , the state became the first to decriminalize aesculapian marijuana ( although its recreational consumption has not been legalized ) . Since then , 22 states and the District of Columbia have expire interchangeable laws , and four of those states have also legalized marijuana ’s amateur use .

The rate of pot - refer hospital care also increased , going from 1.3 per 1,000 people in 2011 to 3.1 per 1,000 people in 2012 , Mair say .
In 85 percent of the case , wellness care workers rag the patient ’s problem as " marijuana abuse , " whereas the other 15 percent were coded as " marijuana dependence . " And in 99 percent of case , the marijuana trouble was the affected role ’s junior-grade code , intend that the person went to the infirmary for something else , Mair said .

Next , the researchers looked up the addresses of the 1,650 medical ganja dispensaries in California in 2012 .

A ' first footprint '
The field of study is a sound " first pace " toward learning about the possible effect of medical marijuana dispensary on pot - relate hospitalizations , Harper said .
" It suggests a possible link betweenmarijuana dispensariesand hospitalizations , but it ’s not definitive , " he say .
The authors also acknowledge that more work is require to study the relationship — sooner , research that look at a modification in neighborhood dispensary over meter , rather of just at one point in time .
“ It ’s unclear if the marijuana dispensaries are simply place in neighborhoods that lean to be more disadvantaged and already have underlie problems with marijuana abuse , or if the presence of the dispensaries is causing an increase in vilification and hospitalization insurance , ” Mair said in the command . " It could be a combining of both factors . "
