"Drug paraphernalia" is a term to denote any equipment, product or accessory that is intended or modified for making, using or concealing drugs, typically for recreational purposes. Drugs such as marijuana, cocaine, heroin, fentanyl, and methamphetamine are related to a wide range of paraphernalia. Paraphernalia generally fall into two categories: user-specific products and dealer-specific products.

User-specific products include glass hashish pipes, crack cocaine pipes, smoking masks, hashish bongs, cocaine freebase kits, syringes, roach clips for holding the burning end of a marijuana joint. Some stores sell items for growing hydroponic marijuana, such as guidebooks, fertilizer, and fluorescent grow-lights. The term "paraphernalia" also refers to items such as hollowed-out cosmetic cases or fake pagers when used to conceal illegal drugs, or products purported to cleanse an individual's system of drug residues to increase the chance of passing a urine analysis drug test.

Dealer-specific products are used by drug sellers or traffickers for preparing drugs for distribution. Items such as digital scales, vials, and small zipper storage bags that can be used to package crack, heroin, or marijuana fall into this category.
