It depends on the form of the drug.

Cocaine salts can be hydrochloride (HCL), sulfate (-SO4) and the nitrate (-NO3).

Crack cocaine is a combination of the alkaloid with backing soda and water.

If the raw leaves are chewed, they are often rolled around lime (Calcium hydroxide, Ca(OH)2).

Coca tea or coca leaf infusions are made by steeping coca leaves in hot water.

Cocaine powder, coke, that is typically snorted may be cut (mixed) with baking soda, baby powder, talcum powder, baking powder, baby formula, powdered laxative, or any other white to whitish powdered substance.
