Smart drugs are typically not nootropics. In fact, most of the substances that are classified as smart drugs do not pass the standards set by Dr.’s Giurgea or Skandia upon the initial discovery of nootropics.
Instead, smart drugs are amphetamine-based, making them stimulants (for example, Adderall). However, there are some drugs like Modafinil that is thought of as a nootropic because it increases levels of the neurotransmitter hypocretin, increasing energy, alertness, and motivation.
Several smart drugs, including Modafinil, are heavily regulated and restricted in the United States. As such, most users turn to alternatives like Adrafinil as an alternative because it converts into Modafinil upon digestion.
