Which of the following influences might cause physical indications of cannabis use?

Body tremors are a recognized physical indication of cannabis use due to the substance’s impact on the central nervous system. When cannabis is consumed, it can alter motor functions and coordination, potentially leading to noticeable tremors or involuntary muscle movements. This effect is particularly relevant when someone is under the influence of cannabis, as it can stem from the active compounds affecting the body's nervous system.

The other influences mentioned, such as high levels of energy, rapid speech, and a calm demeanor, are not typically associated with cannabis use in a physical context. While some individuals might feel more relaxed or sociable when using cannabis, the physical manifestation of tremors is more directly observable and indicative of its effects. These other influences can be linked to different substances or conditions, but tremors are a clearer sign pertaining to cannabis.
