What is a notable indicator of cannabis use characterized by a distinct smell?

The odor of marihuana is a well-known and distinct indicator of cannabis use. Cannabis emits a noticeable and unique smell that can be easily detected in the environment surrounding its use. This odor is primarily due to the compounds called terpenes and can vary in strength and characteristics depending on the strain of the plant. Recognizing this scent is important for law enforcement and other professionals for both detection purposes and to distinguish cannabis from other substances.

While relaxed inhibitions and difficulty in dividing attention can be behavioral effects of cannabis use, they are not physical indicators like the odor. Rolling papers may be related to the consumption method of cannabis but do not serve as an immediate and distinct indicator of use on their own. Thus, the odor of marihuana stands out as the most notable and recognizable sign of cannabis use.
