A pair of papers published today in the journal Addiction have pour some cold water on sure claim about medicinal marijuana .
aesculapian marijuana is now sound in 29 US state , leading some people to contend that this will increase recreational marijuana use . However , thefirst paperfrom Columbia University in New York tell that is not the case .
Conducting a meta - psychoanalysis of 11 studies from four ongoing prominent national sight date stamp back to 1991 , the team found no evidence for addition in recreational use . They say that current evidence “ does not defend the hypothesis that US medical ganja laws ( MMLs ) until 2014 have led to increases in adolescent marijuana use prevalence . ”
They did note , however , that as states get down to decriminalise unpaid marijuana – as has been happen in the last few year – the situation may alter somewhat .
" Although we found no substantial effect on adolescent marijuana usance , we may find that the situation change as commercialized grocery for medical marijuana develop and expand , and as states legalize recreational marijuana function , ” senior author Professor Deborah Hasin , from Columbia University , said in astatement .
“ However , for now , there seems to be no foundation for the line that legitimate aesculapian marijuana increases teen ' use of the drug . "
Thesecond paperdealt with the claim that medical marijuana could lead to a fall in the use of opioids . A study in September 2017 , for illustration , enunciate that medical marijuana could be used to relieve pain , and help stopopioid overdoses .
In 2015 , more than 33,000 multitude died in the US from opioid use . Some studies , though , have show the charge per unit is drip , and attributed it to the legalization of medical marijuana .
However , this composition in Addiction , from the University of Queensland in Australia , articulate that medical marijuana was not needfully creditworthy . It said there was no evidence to intimate one caused the other .
“ There is very weak grounds to support the claim that expanding access to aesculapian cannabis will reduce opioid overdose deaths in the United States , ” the researchers take note .
They added that although some studies do show a correlativity between the increment of medical marijuana use and the reduction of opioid deaths , there was no evidence to suggest it was the cause . correlation coefficient does not always adequate causing .
So , good and tough news show for medical marihuana . While it does n’t seem to be causing an increase in recreational utilisation , some of its purported benefits can not be try out – just yet , anyway .
