Psychoactive substances are substances that act on the central nervous system to produce changes in mood emotion perception or consciousness. These substances can be either naturally-occurring or man-made and can be taken either in the form of drugs food beverages or supplements. Psychoactive substances can be divided into the following categories:

  • Stimulants These substances increase alertness energy and focus and can include caffeine nicotine and amphetamines.
