What form does crack cocaine typically take?

Crack cocaine typically takes the form of small, hard, crystalline rocks or pellets. This form is created by processing powdered cocaine with baking soda or ammonia and water, which is then heated to produce the solid product. The crystalline nature of crack cocaine is what distinguishes it from other forms of cocaine, such as the powdered form that appears as a fine white powder.

In contrast to the options that describe powdered substances or liquids, crack's specific rock-like structure allows it to be smoked effectively, which is a common method of use. This method leads to a rapid and intense high, thus contributing to its classification as a highly addictive substance.
