Narcotic

[Rihanna]

(narrow-sense) An opiate, such as heroin, morphine, codeine, etc.

(broad-sense) A powerful mind-altering substance, usually illegal (tho not necessarily, see [DXM], an over-the-counter narcotic, and [hillbilly heroin], [Ritalin], [Vicodin], etc. which are legally prescribed).

[Sarah]

An opiate, such as heroin, morphine, or opium. It doesnt mean just any super-addictive drug, like meth. Just opioids like codeine.
Too often misused by propagandists and the ignorant as a word to describe any illegal drug that youre not supposed to use. This is probably because of its scary-sounding name, like some sort of hybridization between psychotic and nark, which just sounds awful.
Dont listen to anybody who uses it that way. They have no clue what theyre talking about.
