What physical symptom is often linked to the use of marijuana?

Red puffy eyes are a well-known physical symptom associated with marijuana use. This occurs due to the active compounds in marijuana, particularly THC (tetrahydrocannabinol), which causes blood vessels to expand. The dilation of these vessels can lead to redness and puffiness in the eyes, making this a common sign observed in individuals who have recently consumed marijuana. This symptom can vary in intensity depending on the amount consumed and the individual's physiological responses.

Other options such as increased coordination, staggering, and improved judgment are not typically associated with marijuana use. In fact, marijuana often has the opposite effect on coordination and judgment, potentially impairing motor skills and cognitive function, which leads to concerns about safety and responsible use. Understanding these physiological effects is crucial for those preparing for roles in juvenile justice, where awareness of substance use signs can inform intervention and support strategies.
