A single portion of Freebase Coccaine.
So named for the cracking of the initial rock, into smaller "distributable" pieces.
False origings: Crack was NOT named after a crackling sound. It does not crackle at all... it sizzles as the solid form is reduced to oil which begins to vaporize into the infamous "white cloud".
The term was originally coined on 125th Stree & St. Nickolas Ave in Harlem NY. By Craig.
The song "White Lines" by Grand master Flash & the Furious 5 was dedicated to Craig & the other 3 Base-Heads who were killed in the St. Nick Massacre.
