Replaces traditional treatments: following the legalization of marijuana, the demand for certain medications has decreased.

A recent study revealed that in states where medical and recreational marijuana is legal, there are fewer prescriptions written for anxiety medications. This unusual trend has piqued the interest of scientists, though they approach it with caution, as while the side effects of such medications are well-known, marijuana continues to conceal many of its mysteries from scientific inquiry, reports The Conversation.

The research, published in the JAMA Network Open journal and conducted under the direction of Ashley Bradford, an associate professor in the School of Public Policy at Georgia Tech, focused on analyzing the impact of marijuana laws on the use of privately insured medications, including benzodiazepines, antipsychotics, antidepressants, barbiturates, and sleeping pills.

The findings indicate a consistent decrease in the number of benzodiazepine prescriptions in states with broader access to marijuana. These medications, such as Valium and Xanax, are typically used to combat anxiety by calming the nervous system. However, no significant trends were noted regarding barbiturates and sleeping medications. The study also examined state-level policies, calculated prescription fill rates, average duration of prescriptions, and frequency of refills.

The results demonstrated variability in how marijuana laws affect prescription patterns. Not all states experienced the same reduction, suggesting that differences in marijuana policy frameworks may play a role in these outcomes. The authors believe this research has significant implications for healthcare systems, policy development, and patient treatment.

Despite their effectiveness, benzodiazepines pose risks when misused, particularly in combination with opioids. In 2020, benzodiazepines were involved in 14% of opioid-related overdose deaths. Given that nearly 5% of the population in the United States is prescribed benzodiazepines, substituting marijuana as a treatment option could reduce such risks and lessen negative side effects, scientists stated. Moreover, access to marijuana has become an alternative treatment method for conditions like post-traumatic stress disorder, offering broader therapeutic options for adults, particularly for those facing barriers to traditional psychiatric care.

In 2021, only 65.4% of adults with mental health disorders reported receiving treatment, highlighting the need for accessible alternatives. Despite promising trends, researchers emphasize gaps in understanding the overall picture of the effect. It remains unclear whether the reduction in prescribed medications correlates with improvements in patient conditions.

While marijuana may help alleviate anxiety, the long-term effectiveness and safety of replacing benzodiazepines with it remain insufficiently studied. Additionally, the research noted a slight increase in the use of antidepressants and antipsychotics, although the relationship between marijuana use and conditions such as depression or psychosis requires further investigation, which researchers have begun to pursue more frequently.

The differences in results across states underscore the need for tailored policies that reflect the unique circumstances and goals of individual jurisdictions, as well as the overall societal attitudes. They contribute to a broader dialogue about the role of marijuana in mental health care.

Considering that nearly 23% of the adult population in the U.S. faces diagnosable mental health disorders annually, alternative treatment methods like marijuana could be a step toward addressing gaps in mental health support, the authors believe.

However, policymakers involved in legalization must consider potential unforeseen consequences, such as marijuana's interaction with other treatment methods and its varying effects on different population groups, they warn. Future research may provide clearer answers about the broader health implications and effectiveness of marijuana as a substitute for traditional medications, but the trend of cannabis displacing conventional treatment methods has not gone unnoticed by science.
