Dope was a word for sauce (doop), gravy about 200 years ago. About 100 years ago dope referred to a sauce like version of opium. Drugged up horses were beginning to be referred to as being doped.

Dope also can mean an oil or lubricant, or a varnish that is painted on the fabric covering an aircraft. Pipe dope is a sealant used on pipe threads. Dope is used to stabilize liquid explosives.

Modern usage comes from the widespread use of model airplane glue, which was to be applied only in well-ventilated areas. Breathing the fumes made people "dopey," acting stupid, foolish, and clumsy. The term “dope,” is generally used today to refer to anything that gets people “high,” either pharmaceuticals or the evening news.

Dopers, may appear stupefied, confused, muddled, befuddled, disorientated, groggy, or muzzy.

In the past, and still in some localities, any kind of drug, including “soft” drugs like marijuana. Currently most often used used specifically for heroin. Regional variation can cause confusion.
The antidrug commercials (often featuring marijuana), tagline: “Why do you think they call it dope?”

“Shooting yourself with dope (heroin) is just less efficient than using a gun.”

“Someone scored some great dope and we smoked all day.”
