Going cold turkey is opposed to stopping it by gradually doing it less and less, or stopping it with help like special gum or medicine. You don't get any help; you just stop.
"Cold turkey" is a term describing the actions of a person who gives up his habit or addiction at a single moment, rather than through gradually easing the process through tapering off or supplemental medication. The term allegedly derives from the comparison of a cold turkey carcass and the state of a withdrawing addict -- most notably, the cold sweats and gooseflesh. It is often preceded by the word 'going', as 'going cold turkey'."--Wikipedia

Originates from when a smack (or any opiate for that matter, medical or not) addict stops taking drugs completely. The effects are feeling "cold" (from the inside) no matter what temperature it is or how many blankets you are using.
The turkey part comes from the same origin and when your skin goes goosepimply...like a turkey.
