When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "DrugFacts",
   title = "Heroin --- DrugFacts{,} ",
   year = "2017",
   url = "\url{https://drugfacts.org.uk/index.php?title=Heroin&oldid=133}",
   note = "[Online; accessed 23-January-2026]"
 }
