ELI5:Can a police officer use narcotics if he is undercover? And if so, how does that work?

They absolutely can.  Undercover cops have a lot of leeway to stay undercover and protect themselves.  How does it work?  They do the drug.  That's about it.  They might do less of it so they're not so high they blow their cover.  They go through training to hide the drugs, do less of them and make it look like they're doing more, and to control their actions under the influence.
