Or perhaps it is from Old Norse drukna "be drowned," which has at least influenced the modern form of the word, via North of England dialect. Related: Drowned; drowning.

drug (n.)

late 14c., drogge (early 14c. in Anglo-French), "any substance used in the composition or preparation of medicines," from Old French droge "supply, stock, provision" (14c.), which is of unknown origin. Perhaps it is from Middle Dutch or Middle Low German droge-vate "dry barrels," or droge waere, literally "dry wares" (but specifically drugs and spices), with first element mistaken as indicating the contents, or because medicines mostly consisted of dried herbs.ETD drug (n.).2

Compare dry goods (1708), so called because they were measured out in dry (not liquid) measure, and Latin species, in Late Latin "wares," then specialized to "spices" (French épice, English spice). The same source produced Italian and Spanish droga, Swedish drog.ETD drug (n.).3

Specific application to "narcotics and opiates" is by late 19c., though the association of the word with "poisons" is from 1500s. Druggie "drug addict" is recorded by 1968. Phrase a drug on (or in) the market "thing which has lost its value and is no longer wanted" (mid-17c.) is of doubtful connection and may be a different word, perhaps a play on drag, which was sometimes written drug c. 1240-1800.ETD drug (n.).4

Hence, literally, perhaps, "they who know the oak" (perhaps in allusion to divination from mistletoe). Anglo-Saxon, too, used identical words to mean "tree" and "truth" (treow).ETD Druid (n.).2

The English form comes via Latin, not immediately from Celtic. Old English had dry "magician," presumably from Old Irish drui. The Old Irish form was drui (dative and accusative druid; plural druad), yielding Modern Irish and Gaelic draoi, genitive druadh "magician, sorcerer." Not to be confused with the United Ancient Order of Druids, a secret benefit society founded in London 1781.ETD Druid (n.).3

Not common before 1570s; the slightly older, and more common at first, word was drumslade, apparently from Dutch or Low German trommelslag "drum-beat," "though it does not appear how this name of the action came to be applied to the instrument" [OED], and the English word might be a shortening of this. Other earlier words for it were tabour (c. 1300, ultimately from Persian; see tabor) and timpan (Old English; see tympanum).ETD drum (n.).3

In machinery, the word was applied to various contrivances resembling a drum from 1740. In anatomy, "the tympanum of the ear," 1610s. Meaning "receptacle having the form of a drum" is by 1812.

ducky (adj.)

"excellent," slang from 1897 (often ironical),perhaps from duckie as a term of endearment (by 1853). Rev. Palmer ["Folk-Etymology," 1882] finds the use of duck as a term of endearment "identical with Danish dukke, a baby or puppet (Wolff), Ger. docke, a doll or puppet, Shetland duckie, a doll or little girl ...," and thinks it probably is not a metaphoric use of the water-bird word, or related to the much earlier slang or dialectal noun meaning "a woman's breast" ["...whose pritty duckys I trust shortly to kysse," Henry VIII, c. 1536 letter to Anne Boleyn, who, contrary to historical rumor, did not have three of them], which perhaps is from dug (n.).ETD ducky (adj.).2

Duct tape originally was duck tape (1894), long, non-adhesive strips of plain cotton duck cloth used in various mechanical processes; from duck (n.2). The name was transferred to a plastic-coated adhesive tape used by U.S. soldiers in World War II (perhaps in part because it was waterproof). It continued in civilian use after the war, and the name shifted to duct tape by 1958, perhaps because it was frequently used on air ducts, which also accounts for its standard silver-gray color.ETD duct (n.).3

The vogue word of 1883, originally used in reference to the devotees of the "aesthetic" craze, later applied to city slickers, especially Easterners vacationing in the West (as in dude ranch "ranch which entertains guests and tourists for pay," attested by 1921).
