Causing a state of unconsciousness or a lack of awareness, often similar to the effects of drugs.

Narcotizing → It is formed from "narcot-" (from Greek "narkōsis", meaning numbness or stupor) and "-izing" (a suffix indicating the process of making or causing). The word "narcotizing" refers to the process of inducing a state of numbness or stupor, often through the use of narcotics.
Think of 'numbness' ('narcot-') being caused by a process ('-izing') — that's why narcotizing means to make someone numb.
