Elevated drug overdose mortality among Americans who visit Florida, 2003-2020.

OBJECTIVE:Florida state has played a conspicuous role in the current U.S. drug epidemic. Reports suggest that even non-Florida residents may suffer excessive overdose fatalities while visiting the state, possibly in connection to two sets of events: (1) the overprescribing of controlled substances, and more recently, (2) the exploitation of patients' insurance benefits by unscrupulous operators of substance use treatment facilities in Florida. To date, however, no research has examined the overdose fatalities of non-Florida residents inside Florida. METHODS:Death certificate data were used to calculate proportionate mortality ratios for overdoses among Florida residents and visitors. Deaths occurring in the rest of the USA were used as reference populations. RESULTS:Between 2003 and 2020, overdose mortality was slightly elevated for Florida residents within their home counties (106.7 (95% CI 105.8 to 107.5)) and in other Florida counties (113.0 (95% CI 110.0 to 116.0)). Significantly, this mortality was much higher among out-of-state visitors in Florida (163.1 (95% CI 157.5 to 168.8)). When analysed by year, greater overdose mortality among visitors coincided with years when drug prescribing in Florida was rampant, and with the advent of expanded insurance coverage for substance use treatment. During this more recent period (since 2014), overdose mortality was exceptionally high for out-of-state visitors in Palm Beach County, where reports of malpractice in the Florida treatment industry have been concentrated. CONCLUSIONS:Overdose mortality was disproportionately high among out-of-state visitors in Florida. The results suggest that the regulatory policies in Florida may be implicated in drug-related casualties of people who live in other parts of the USA.
