Pot is a colloquial term for cannabis or marijuana. It is often used to refer to the dried flowers or buds of the cannabis plant that are commonly smoked or consumed for their psychoactive effects. Cannabis plants have had many slang terms over the years, such as pot, grass, weed, ganja, Mary Jane, and many others. You might hear growers refer to their pot plants just as much as they talk about cannabis or marijuana plants. Only female pot plants produce the most prominent cannabinoids connoisseurs are familiar with, such as THC and CBD.
