Which of the following is a common side effect of cannabis?

Cannabis is known to cause specific physiological effects due to its interaction with the body’s endocannabinoid system. One of the well-documented side effects of cannabis use is bloodshot eyes. This occurs as a result of the active compounds in cannabis, particularly tetrahydrocannabinol (THC), which can lower blood pressure and lead to vasodilation. The dilation of blood vessels in the eyes causes them to appear red and bloodshot.

This effect is commonly associated with cannabis use and is often noticeable shortly after consumption. It contrasts with the other options: increased energy is not typically a recognized side effect of cannabis; baldness is unrelated to cannabis use; and enhanced memory is also not a common effect, as cannabis can impair short-term memory in some users. Therefore, the presence of bloodshot eyes stands out as a relevant and typical side effect of cannabis consumption.
