What are Drug Schedules?

A schedule or class is a way of dividing drugs into different categories. Each legally controlled substance falls into a certain schedule based on its various qualities. A drug’s schedule is one of the factors that determine the penalty for possessing or selling it. Of course, the illegal use of any drug can be punished harshly, even if it is in a relatively mild schedule.

Drug Schedules and Wisconsin Law

Wisconsin law recognized five different classes of controlled substances. Each substance is placed in a class according to its potential for abuse, possible medical uses, and addictiveness. The schedules and some common examples of each include:

  • Schedule 1 Drugs: High potential for abuse and no accepted medical use. Common examples include LSD, heroin, and marijuana.
  • Schedule 2 Drugs: High potential for abuse and addiction, but some accepted medical uses. Common examples include amphetamines, morphine, and many strong painkillers.
  • Schedule 3 Drugs: Moderate potential for abuse or addiction, and some accepted medical uses. Common examples include anabolic steroids, PCP, and the sedative LSA.
  • Schedule 4 Drugs: Low potential for abuse or addiction, with accepted medical uses. Common examples include anti-anxiety medications such as Valium, and sedatives like Phenobarbital.
  • Schedule 5 Drugs: Lower potential for abuse or addiction than Schedule 4 drugs, with accepted medical uses. Common examples include cough suppressants containing small amounts codeine, and anti-diarrheal medications that contain trace amounts of opium.
