The cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ.

In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales. Most regulated cannabis is grown indoors.

Occupational diseases, including asthma, are an emerging concern in the rapidly expanding U.S. cannabis industry. Cannabis cultivation and processing technicians may be exposed to numerous respiratory hazards, e.g. organic particulate matter and dust from ground cannabis flower, mold, bacterial endotoxins, and pesticides. Employees exposed to ground cannabis without adequate controls are at risk of developing occupational asthma which can be fatal.
