Study: Persistent Cannabis Use Associated With Reduced Body Mass Index
East Lansing, MI: The use of cannabis over time is inversely related to obesity, according to data published in the International Journal of Epidemiology.
A team of Michigan State University researchers assessed the relationship between cannabis use and body mass index (BMI) over time in a nationally representative sample of 33,000 subjects.
Investigators reported that cannabis-using subgroups exhibited “appreciably attenuated BMI gain” over the trial period as compared to non-users and quitters, “with the largest attenuation seen in the ‘persistent use’ group.”
They concluded: “This new prospective study builds from anecdotes, pre-clinical studies and cross-sectional evidence on inverse associations linking cannabis use and obesity and shows an inverse cannabis–BMI increase association. Confirmatory studies with rigorous cannabis and BMI assays will be needed.”
