Three Interesting Facts

  • Many of these substances (especially the stimulants and depressants) can be habit-forming, causing chemical dependency and may lead to substance abuse
  • Conversely, others (namely the psychedelics) can, in certain circumstances, help to treat and even cure such addictions
  • Psychoactive drugs disrupt the communication between neurons (brain cells), so abusing them can have serious short- and long-term effects on the brain
