Smart drugs, also known as nootropics, are substances that are claimed to improve cognitive function, such as memory, focus, and creativity. While some studies have shown that certain smart drugs may have modest effects on cognitive performance, the evidence is often limited and inconsistent. Additionally, there is concern about the potential side effects of smart drugs, which can range from mild (headaches, nausea) to severe (liver damage, seizures). Given the limited evidence and potential risks, it is important to consult with a healthcare professional before considering the use of smart drugs.
