Recreational marijuana could be having an effect on grocery stores.
A new study found sales of potato chips, cookies and ice cream increased in Colorado, Oregon, and Washington just as recreational marijuana became legal in those states.
Professors from the University of Connecticut and Georgia State University compared monthly retail scanner data from 2006 to 2016.
Colorado and Washington legalized recreational use of the drug in 2012, and Oregon’s recreational use became legal in 2015.
Researchers pointed out there’s no data to support that marijuana consumption actually causes a physical craving for junk food.
The findings were published in Social Science Research Network.
