Which of the following is a sign of Cannabis Intoxication?

Increased appetite is indeed recognized as a sign of cannabis intoxication and is commonly referred to as "the munchies." This effect occurs due to the interaction of cannabinoids with the brain's endocannabinoid system, which plays a significant role in regulating hunger and appetite. Users often report heightened food cravings and increased consumption of food while under the influence of cannabis.

The other choices represent conditions that are not typically associated with cannabis intoxication. For example, severe depression is more indicative of mood disorders or may arise in cases of cannabis withdrawal rather than intoxication. Visual hallucinations can occur with very high doses of cannabis, but they are not a standard sign of intoxication and often indicate potential cannabis-induced psychosis rather than typical usage effects. Similarly, severe headaches are not a recognized symptom of cannabis intoxication; in fact, some users report relief from headaches and migraines. Thus, increased appetite stands out as the correct answer in the context of cannabis effects.
