Marijuana can be used in a number of ways. Marijuana can be smoked in joints (like a cigarette), in blunts (cigars or cigar wrappers that have been partly or completely refilled with marijuana), or in bongs (pipes or water pipes). Marijuana also can be mixed or infused into foods like cookies, cakes, or brownies (called edibles) and can be infused in drinks.

It can be vaped using electronic vaporizing devices (i.e., e-cigarettes or vape pens) or other vaporizers. Compounds (or cannabinoids) in marijuana can also be extracted to make oils and concentrates that can be vaped or inhaled. Smoking oils, concentrates, and extracts from the marijuana plant, known as "dabbing," is on the rise. Health and safety risks exist for each of the different ways of using marijuana.

Smoking is the most common way people use marijuana. People smoke joints (homemade marijuana cigarettes), blunts (hollowed-out cigars filled with marijuana), bongs (usually glass water pipes), bubblers (mini-bongs the size of a pipe) and hookahs..
