What might be a sensory indication of cannabis influence?

The presence of the odor of marijuana serves as a clear sensory indication of cannabis influence. Cannabis plants and products have a distinct and recognizable smell, often described as earthy or skunky. This odor can be detected both on the person using cannabis and in the environment where it has been consumed. Law enforcement and corrections personnel often use the smell as a preliminary indicator when assessing whether someone may be under the influence of cannabis, especially in scenarios where visual signs of impairment may not be immediately apparent.

While options like increased appetite might also be associated with cannabis influence, they are not sensory indications that can be directly observed in the same immediate fashion as the odor. Similarly, loss of smell and intense focus on tasks do not directly relate to the sensory detection of cannabis use. The immediate and apparent nature of the marijuana odor makes it a reliable indicator in identifying potential cannabis influence.
