Crack Cocaine

Crack Cocaine

Freebase/crack cocaine. Freebase/crack is derived from cocaine hydrochloride which has been chemically treated with ammonia (freebase) or baking-powder (crack) to free the potent base material from the salt.

Free-base was originally produced by a dangerous four-or-five step process in which the hydrochloride salt was heated with water and a volatile liquid such as ether.

Base cocaine in the form of 'crack' is safer to produce; Crack/free-base is indissoluble in water, so it can't easily be injected or sniffed.  it is smoked in pipes; burnt on tin foil; or mixed with tobacco and weed in a joint.
