Correction to: Harm Reduction Journal (2023) 20:48 https://doi.org/10.1186/s12954-023-00780-3

Following publication of the original article [1], in this article the affiliation details for Author A were incorrectly given as ‘Public Health Division, State Health Department, Alor Setar, Kedah, Malaysia’ but should have been ‘Public Health Division, State Health Department, Kuala Terengganu, Terengganu, Malaysia’.

The original article has been corrected.
