Increased Brain Blood Flow
Some people will question how smart drugs supposedly enhance the brain’s output. There are a couple of explanations that reveal why it may work. First, they reportedly increased the flow of blood to the brain which increases the oxidation levels. This also allows the easier transportation of chemicals like dopamine.

Some medical experts question whether it is safe to artificially induce this response. There’s a lot of work to be done regarding smart drugs but it’s a fascinating area (via Amen Clinics).
