Which of the following is a potential long-term effect of methamphetamine use?

• A. Permanent enhancement of cognitive abilities
• B. Cognitive deficits and memory loss
• C. Improved emotional regulation
• D. Decreased physical health risks

Answer: (B)

The potential long-term effect of methamphetamine use that is accurately identified is cognitive deficits and memory loss. Chronic use of methamphetamine can lead to significant changes in brain structure and function, particularly affecting areas involved in memory, decision-making, and impulse control. Research indicates that individuals with a history of meth use may experience long-term impairments in short-term memory, learning, and overall cognitive function. This decline is attributed to the neurotoxic effects of methamphetamine, which can lead to damage in dopamine pathways and other critical areas of the brain.

The other options suggest outcomes that are not associated with chronic methamphetamine use. For instance, the idea of permanent enhancement of cognitive abilities is inaccurate, as long-term use is linked to cognitive decline rather than improvement. Similarly, improved emotional regulation does not align with the known effects of meth use, which often include increased anxiety, irritability, and mood disorders. Decreased physical health risks is also misleading, as methamphetamine use is tied to numerous health issues, including cardiovascular problems, dental issues, and malnutrition. Thus, the effects of methamphetamine on cognitive function highlight the serious impact of substance abuse and the importance of interventions for those affected.
