it refer to a habitual user of cannabis. Typically a derogative term, a stoner is someone who loves getting high, no matter what time of day. Often, they’re a part of a subculture that identifies with marijuana smoking and may be forgetful or slow at times. Some use the term as a source of pride, and can be reverential. Someone who casually smokes marijuana occasionally, on the other hand, would not be considered a stoner by actual stoners.
