A new study published in BMJ Open makes the case for a link between weed legalization and increased heart issues in a location.
The study looked into 50 million discharges between 2012 and 2018 in US states that legalized marijuana. The years were specifically chosen to range from before legalization to afterwards. These were then compared with states that didn’t legalize in these years.
It found an increase in the legalized states for myocardial infarction, atrial fibrillation, and heart failure.
“These findings set the stage for future research to define the cardiovascular impact of cannabis policies through more granular data and policy experiments. Cannabis sales data might be used to assess the association between cannabis formulations (edible versus inhaled, or combustible versus non-combustible products) and outcomes. Finally, states that have not yet legalized recreational cannabis might coordinate the timing of legal sales to study the effects,” said the authors in the analysis.
Troubling findings, but as always, too soon to find causality.
