Dopers are dope users. They may appear stupefied, confused, muddled, befuddled, disorientated, groggy, or muzzy.

Originally dope adhesives used for model airplane glue were to be applied in well-ventilated areas only. Breathing the fumes made people dopey, acting stupid, foolish, and clumsy.

The term ‘dope,” is generally used to refer to anything that gets people high either pharmaceuticals or the evening news.

A dopant, is an impurity added to a substance to alter its properties just as dope is an impurity added to a brain that alters consciousness in a Doper.
Two classes of dopers can be expected in sports contests.

Throughout history, the "Indominable Spirit of Man" has harnessed many epic, great things. Electricity, the Wheel, firearms, and numerous others too easily mentionable. One thing that man has harnessed that negates itself and diminishes the creativity and genius of man is Marijuana. More specifically, one who feels the need to escape from their everyday life or society at large is commonly referred to as a "pothead" or "weedhead". Pathetic in nature, having a lack of real social skills, and influence are common reasons why people feel they need to smoke dope, or weed. A "doper" is a person in society that cannot function on their own, and needs a crutch to escape their anxiety or pressure with something. Many times relying on the good nature of an increasingly tolerant society, dopers escape their pathetic lives for a few hours of being hungry, lazy and non-motivated because in truth they are too afraid to confront their problem head on and solve whatever it may be, or they are simply too weak to actually do anything helpful about their "problem" that they may have to escape from. Dopers are usually found on street corners, trying to sell or pander to other easily influenced dopers or problem cases to gain profit for their next "fix". A day is not a day unless a doper ravages their senses with the pungent stink of marijuana, and often times beyond the slums and ghettoes of America, dopers can be found in redneck bars, rap concerts, welfare lines, low income housing, and Sublime cover band concerts in local dive bars. Because more and more prisons are full, more dopers are allowed out on the streets so that they may take advantage of the generosity of others and infest high schools with their lazy attitudes and non-existent work ethics. Dopers are an unnecessary part of society that prides itself on conversing slowly, sitting still on couches, and in general, not really bothering to do anything besides strum guitars and surf.
Dopers are an unnecessary part of society.

Dopers should be thrown in jail.

A dial-a-doper is a street-level member of a drug organization, the one who takes calls from customers, then drives to a location to make the exchange.
