A crack head is someone who smokes crack, eats crack, or ingests crack in any way. Crack, also known as "rocks", "the poor man's coke", and "that shit my cousin ray-ray be sellin' 20 dollars a rock" is an illegal and highly-addictive stimulant drug sold and produced in the run-down parts of cities known as ghettos. Crackheads have a rich cultural heritage originating in the south-side of every major city since the 1980's. Along with a highly sophisticated street-lingo, crackheads continue to hold an important and respectable position in the world today.
