What behavioral sign might indicate someone is under the influence of cannabis?

Relaxed inhibitions are a classic behavioral sign of cannabis influence. When individuals are under the influence of cannabis, they often experience a decrease in anxiety and social restraint, which can lead to more open or relaxed behaviors. This may include increased sociability or laughter, as the substance tends to lower inhibitions, making people feel more free to express themselves.

The other options tend to describe behaviors that are generally not associated with cannabis use. For instance, excessive activity is more indicative of substances like stimulants. Heightened focus is also unlikely, as cannabis is more known for creating a state of relaxation and potentially decreased attention. Similarly, quick decision-making is not characteristic of cannabis intoxication, as users may exhibit slower response times and indecisiveness due to its effects on cognitive function. Therefore, the presence of relaxed inhibitions is a key indicator of someone under the influence of cannabis.
