Drug Classifications

Drugs are typically classified in one of three areas: Uppers, Downers and All Arounders. Each classification of drug will have a different effect on the user. For information about specific drugs, click along the left hand column.

If you’re curious about experimenting with a certain drug(s) we encourage you to make an appointment with one of our alcohol and drug counselors. They are a great resource for drug information and can answer your questions. Appointment Line: 893-3371


UPPERS (Stimulants):

Although there is a great difference in strength, all stimulants increase the chemical and electrical activity in the central nervous system.

  • Boost energy
  • Raise heart rate and blood pressure
  • Increase respiration
  • Reduce appetite and thirst
  • Makes user more alert, active, confident, anxious, restless, and aggressive

Uppers include:

Adderall, Cocaine, Hookah, Meth, and Nicotine.


DOWNERS (Depressants):

In general, downers, which are central nervous system depressants, depress the overall functioning of the central nervous system.

  • Sedation
  • Muscle relaxation
  • Drowsiness
  • Disinhibition of impulses and emotions

Downers Include:

Alcohol, Heroin, and Oxycontin/Vicodin.


ALL AROUNDERS:

All arounders usually act as stimulants and occasionally as depressants but mostly psychdelics dramatically alter a user’s perception and create a world in which reason takes a back seat to intensified sensations by creating illusions, delusions, or hallucinations. Much of the information about the effects of psychedelics has been anecdotal rather than the result of extended scientific testing.

All Arounders Include:

Acid/LSD, Ecstasy, Marijuana, Mushrooms, PCP, and Salvia.
