Correction to: Harm Reduct J (2021) 18:99 https://doi.org/10.1186/s12954-021-00545-w

After publication of the original article [1], an error was identified in the last sentence.

The sentence currently reads: Third parking checking will remain constrained without public health support and exemptions that recognize the challenges of drug checking within prohibition and substance use stigma.

The sentence should read: Third party checking will remain constrained without public health support and exemptions that recognize the challenges of drug checking within prohibition and substance use stigma.

The original article has been corrected.
