Dilated pupils, also known as mydriasis, are commonly associated with certain drug categories, particularly stimulants and hallucinogens. Stimulants, such as cocaine and amphetamines, activate the sympathetic nervous system, leading to physiological responses like pupil dilation. Similarly, hallucinogens, including substances like LSD and psilocybin, can also result in dilated pupils due to their effects on neurotransmitter systems and the brain's processing of sensory information.

Cannabis can sometimes cause changes in pupil size, but it more frequently results in constricted pupils rather than dilation. This is why the presence of cannabis in the correct answer reinforces the association with stimulant and hallucinogenic substances, as those drugs are the primary contributors to the effect being assessed.

In summary, the combination of stimulants and hallucinogens explains the characteristic of dilated pupils, underscoring their role in altering autonomic nervous system activity.
