Which cognitive side effect can result from marijuana use in a developing brain?

The negative impact on learning is a significant cognitive side effect associated with marijuana use, particularly in the developing brain of adolescents and young adults. Research indicates that marijuana can affect the brain's neurotransmitter systems, particularly the cannabinoid receptors, which play a crucial role in cognitive processes such as attention, memory, and learning. In younger individuals, whose brains are still maturing, marijuana use has been linked to impairments in short-term memory, decreased motivation, and challenges in academic performance.

In contrast, the other options suggest positive outcomes or benefits that are not supported by evidence related to marijuana use. Positive emotional stability, improved socialization, and enhanced problem-solving abilities are not typically associated with marijuana use, especially in the context of cognitive development. Instead, studies show that continued use can exacerbate issues such as anxiety, depressive symptoms, and social withdrawal, which are detrimental to overall emotional and social functioning. Hence, the correct association regarding cognitive side effects from marijuana in a developing brain centers squarely on its negative impact on learning capabilities.
