Legalizing Marijuana Reduces Personal Bankruptcy Rates As Arrests Decline, Study Shows
U.S. states that legalize recreational marijuana see personal bankruptcy rates decline—an effect that seems to be associated with reduced arrests that can create compounding financial problems, according to a new study.
Researchers looked at data on personal bankruptcy cases, state cannabis laws and FBI crime data from 2001 to 2024, determining that ending cannabis criminalization is linked to improved financial outcomes.
The study, published this month in the journal Finance Research Letters, found “evidence consistent with a legal-cost mechanism.” That is, adult-use cannabis legalization “sharply reduces marijuana arrests, and states with larger arrest declines exhibit larger bankruptcy declines.”
“U.S. recreational marijuana legalization reduces personal bankruptcy rates. States with larger marijuana-arrest declines see larger bankruptcy declines.”
“By reducing households’ exposure to criminal justice costs such as fines and legal fees, [legalization] may ease the acute financial shocks that can tip vulnerable households into insolvency,” the study authors, who are affiliated with Shenzhen University in China, wrote.
The average reduction in arrests post-legalization stands at 87 percent “without affecting broader crime rates,” the study points out. Bolstering the study’s key finding, data showed that states where there were larger reductions in cannabis arrests were associated with “larger declines in personal bankruptcy.”
“Furthermore, we find that economically stronger states experience more pronounced reductions in bankruptcy following legalization,” the study concluded.
“Using state-year panel data from 2001 to 2024, this paper presents evidence that recreational marijuana legalization is associated with a reduction in the personal bankruptcy rate in the United States. This result is stable across a battery of robustness checks. Heterogeneity analysis reveals that the effect is stronger in economically stable states, specifically those with lower baseline unemployment and bankruptcy rate, and higher median household income.”
A separate study from 2020 relatedly investigated the impact of legalization on the broader economy, with researchers at the University of Iowa analyzing 9,810 corporations between 1991 and 2017, finding “a multitude of positive effects” after a state enacts medical marijuana laws.
“Firms headquartered in marijuana-legalizing states receive higher market valuations, earn higher abnormal stock returns, improve employee productivity, and increase innovation,” the authors said.
