Cocaine comes in two primary forms — powder and crack — each with a distinct appearance. However, because cocaine is routinely mixed with cutting agents, its appearance can vary significantly.

Powder cocaine

Cocaine hydrochloride is a fine white crystalline powder. High-purity cocaine has a pearly or iridescent quality and clumps slightly when pressed. It is odorless or has a faint chemical or floral smell. As cocaine is cut with additives (baking soda, talcum powder, laxatives, lidocaine, levamisole), the powder may become duller, chunkier, or take on a slight off-white or yellowish tint. Heavily cut cocaine may not clump and may feel more powdery or gritty.

Crack cocaine

Crack is cocaine that has been processed with baking soda or ammonia and water into a solid form. It appears as small, irregularly shaped rocks or chunks. Color ranges from off-white to yellowish to pale pink. Crack rocks have a hard exterior but a somewhat waxy or oily texture when broken open. They make a crackling sound when heated — which is how the drug got its name.

Fentanyl contamination

Like heroin, the cocaine supply is increasingly contaminated with fentanyl. This is particularly dangerous because cocaine users typically have no opioid tolerance, making even small amounts of fentanyl potentially lethal. Fentanyl cannot be detected visually in cocaine. This contamination is responsible for a growing number of overdose deaths among people who believed they were using only cocaine.

Paraphernalia

For powder cocaine: small bags or vials, mirrors or flat surfaces with powder residue, razor blades or credit cards (for cutting lines), rolled bills or cut straws (for snorting), and small spoons. For crack cocaine: small glass pipes (often straight tubes with steel wool as a filter), lighters or torches, and small bags with rock-like residue.
