Types of Wisconsin Drug Charges

Many states, including Wisconsin, continue to see a rise in drug offenses connected to opioid use. With the rise in popularity of opioids, additional substances continue to emerge, such as Fentanyl and synthetic marijuana. 

Drug charges or controlled substance charges in Wisconsin can range from misdemeanors to felonies depending on three things:

  1. The type of substance
  2. The amount of the substance found in your possession
  3. Your prior history of drug offenses


The most common drug offenses involving non-prescription, illicit substances typically include marijuana, cocaine, methamphetamine, LSD, and heroin, among others.

Wisconsin law adheres to the scheduling system of drug categorization, which delegates penalties according to each drug’s risk of abuse.

What is the drug scheduling system in Wisconsin?

Wisconsin's drug scheduling system is the system of classification for drug-related criminal offenses based on the drug or controlled substance associated with the criminal charge. This schedule is broken down into five categories or schedules.

Schedule 1 Drugs:

Wisconsin law classifies substances found to be the most dangerous to users with a high risk of dependency and no legitimate medical use as Schedule I controlled substances. Some examples of Schedule I drugs in Wisconsin include:

  • Synthetic Opiates, such as Fentanyl
  • Opiates, such as Heroin
  • Hallucinogens, such as MDA, LSD, PCP, GHB, THC and synthetic cannibinoids
  • Depressants
  • Immediate Precursors
  • Stimulants
For important information about synthetic cannibinoids or fake pot, read the article, "Understanding Synthetic Marijuana Use in Wisconsin" by Stangl Law.

Schedule 2 Drugs:

While Schedule II controlled substances in Wisconsin are also found to have a high risk of abuse, Wisconsin law recognizes that they may have some medical value. Examples of Schedule 2 drugs or controlled substances under Wisconsin's drug laws include:

  • Opium and opium-derived substances, such as Codeine, Morphine and Oxycodone
  • Cocaine
  • Methamphetamine
  • Methadone
  • Opium

Schedule 3 Drugs:

The list of Schedule III controlled substances in Wisconsin is comprised of drugs which are somewhat less dangerous than Schedule 2 substances, but still carry some risk of dependency. Examples of Schedule 2 drugs in Wisconsin includes:

  • Codeine
  • Testosterone
  • Ketamine
  • Hydrocodone

Schedule 4 and Schedule 5 Drugs in Wisconsin:

Schedule IV controlled substances and Schedule V controlled substances drugs carry even less risk than Schedule III controlled substaces and provide even more medical uses. Most of these drugs are common prescription medications.

Possible sentences for Wisconsin drug charges

Drug possession penalties are generally broken down according to their corresponding schedule. Here is a generalized breakdown for reference:

First-time possession for Marijuana, Cocaine, Methamphetamine, and LSD are all classified as misdemeanors for first-time offenders. Fines can range from $500 to tens of thousands depending on the circumstances and the substance in question.

Second-time offenses often have doubled fines and/or jail sentences.

First-time offenders may be eligible for Conditional Discharge under Wisconsin law.

This is a period of probation prior to judgment being entered. If completed successfully, you will be discharged with your charges dismissed from court. This usually involves drug testing, curfews, employment requirements, and/or addiction treatment programs.

Possible defense strategies for drug charges in Wisconsin

While drug possession charges often carry very serious consequences even for those who have little or no prior history of drug-related offenses, there are a number of defense strategies, which have proven useful to defendants in court.

Challenging the search and seizure process. One strategy challenges the search and seizure process, which was carried out on your person or property by law enforcement.

Challenging probable cause. Police officers require probable cause in order to perform a search on an individual or their vehicle. Search warrants are required to enter homes. By presenting an argument challenging the presence of probable cause, you may convince a judge that your rights have been violated, thus making any evidence collected during that period inadmissible in court.

Other defense strategies may bring to light your knowledge of the substances being in your possession in the first place.

If charged with marijuana possession with no previous arrests, it is sometimes possible to have your charge downgraded to an ordinance violation given you were found to possess a small amount of the substance.

What to do if you’ve been charged with possession or another drug-related crime in Wisconsin

Wisconsin prosecutors often bring stiff penalties for drug offenses of any kind. As a result, it’s imperative to contact an attorney with experience defending cases like yours as quickly as possible.

As I’ve said in previous posts, avoid running the risk of incriminating yourself by keeping silent around law enforcement after your initial arrest. Do not accept any kind of plea bargain or guilty plea before an attorney has had a chance to review your case.
