Which of the following is NOT a sign of cannabis intoxication?

Diuresis is not a sign of cannabis intoxication. Cannabis is known to cause several physiological effects, and among them are conjunctival injection (red eyes), increased appetite (commonly referred to as "the munchies"), and dry mouth (often described as "cottonmouth").

Conjunctival injection occurs due to the vasodilatory effects of THC, the psychoactive component of cannabis, leading to blood vessel expansion in the eyes and resulting in redness. Increased appetite is a well-documented effect, as cannabis influences certain brain pathways that regulate hunger. Dry mouth can occur due to the drug's anticholinergic effects, which reduce saliva production.

Conversely, diuresis refers to increased urination, which is typically not associated with cannabis use. In fact, users may experience a reduction in urination due to the dehydrating effects of the drug. Therefore, while cannabis intoxication has several characteristic physical signs, increased urination is not among them, highlighting why diuresis is the correct answer in this context.
