Last month we discussed the new study published in JAMA (The Journal of the American Medical Association) showing that drug overdose deaths due to opioids declined in 13 states that legalized medical marijuana. The study just looked at death rates overall due to opioids and noted that they happened to decline up to 30% in states that legalized medical marijuana. Today, I expand on the findings.
This study is great, sensational news, but in reality, it is a leap of faith that these two subjects are truly correlated. Opioid overdose and deaths are a very complex issue. The overdose of opioids is linked to many things, especially recreational use. The death rate from overdose is related to many factors, including whether the overdose was accidental or on purpose, such as a suicide. Furthermore, the access to treatment for overdose is important, especially whether first responders can recognize it and provide drug reversal rapidly and then get a person to a hospital for support. So, if you are using opioids to get high, it does not matter if marijuana for medical use is legal since they are not using it.
Medical marijuana is used for a variety of problems, including nausea related to cancer, seizures, and glaucoma. None of those conditions have much to do with opioids and drug overdoses. So if marijuana is legal for glaucoma or treating seizures, why would death rate due to narcotic overdose change? Rationally, it would not.
Unfortunately, this is just another example of a study finding a nice statistic that has no true correlation to the data. This study did not specifically look at factors that are related to opioid overdose death. If the study actually looked at reasons related to opioid overdoses, treatments, and deaths, there may be some validity. Rewarding medical marijuana with this lofty success is poor research and data interpretation. A prestigious journal, JAMA, should do much better at critically analyzing research and publishing articles. This is an amazingly poor job of data analysis and conclusions with an over simplification of causes of opioid related deaths.
