Parenteral administration of antipsychotic medications avoids first pass metabolism. As a result of this, medications administered parenterally work faster and have greater clinical effect, due to higher brain bioactivity. In the case of medications not administered parenterally, many times they are rapidly metabolized by the liver before reaching the bloodstream.

The Harrison Act of 1914 prohibited the sale of narcotics and cocaine without prescription. Prior to this legislation, both cocaine and opiates could be easily purchased in pharmacies and were widely and legally used by Americans of all social classes. It is thought by some that heroin addiction became less common after the Harris Act was passed, but many experts believe that formal prohibition of narcotics has had no significant effect on abuse frequency.
