Cluck is one of the many euphemisms in use, to describe going cold turkey ,a sudden stoppage of the addictive drug heroin and other opiates and opioids (e.g morhine, methadone, codiene, Fentanyl, opium and many more, marketed pain killers)

The term, cluck derivates from the term cold turkey, owing to the fact that when withdrawing from these drugs, one of the many withdrawal symptoms include goosebumps, like those on a plucked turkey. ** In the song 'Cold Turkey' by John Lennon, there is a lyric; "...Goose Pimple Bones" **

Too be fussy, the word should really be gobble as that's the sound turkeys make, but, as you may, or may not, know; gobble has taken on a different meaning..

There are many, many euphemisms for withdrawing from heroin/opiates etc., but others relevent to turkey/cluck are: to roast or roasting, clucking, spitting feathers and being oven ready!

That's where cluck comes from! Not crack!, although clucking has become a generic term for withdrawing from any addictive substace - as cold turkey has also done. But (as explained above) they originate from opoid withdrawal symptoms.

Clucken, adj. The act of begging for dope.

The act of exchanging some item of value for a given controlled substance (or cash to be used in the purchase thereof), as carried out by an addict of that substance when an otherwise exhaustive search has failed to yield the funds necessary to support his habit. The quantity of drugs received for the object of a cluck tends be very small in relationship to the item's perceived market value. This discrepancy can be attributed to the efforts of the person receiving the cluck to capitalize on his knowledge that the clucker has reached a state of desperation, in which he is liable to forego any attachment to material possessions, as well as any remaining vestige of common sense (often to the point of inevitable regret), in exchange for the opportunity to satiate his physical cravings for even the shortest duration.
