What problem can prolonged cannabis use lead to?

Prolonged cannabis use can potentially lead to reproductive problems, which is why this choice is accurate. Research has indicated that regular cannabis consumption may have an impact on hormonal balances and reproductive health in both males and females. In males, it can affect testosterone levels and may lead to issues such as decreased sperm production and quality. In females, cannabis use has been linked to menstrual cycle irregularities and potential effects on fertility.

In contrast, while the other choices may imply benefits or positive outcomes, they do not align with the established effects of prolonged cannabis use. Improved cognitive function and enhanced immune function are not supported by evidence; instead, extended use can lead to cognitive impairments and may negatively affect immune response. Increased aggression is a more complex outcome, which has not been consistently linked to cannabis use, especially in the same way it is documented for other substances like alcohol or stimulants.
