POSSESSION OF A CONTROLLED SUBSTANCE
POSSESSION OF A CONTROLLED SUBSTANCE
OVERVIEW
Possession of a controlled substance is a serious matter that can have lasting consequences on your freedom, reputation, and future. Whether the charge involves a small amount of marijuana, prescription medication without a valid prescription, or more serious narcotics like cocaine, heroin, or fentanyl, the legal stakes are high.
Possession charges can vary widely depending on the type and quantity of the substance, as well as whether there are any prior offenses. Even a first-time offense can result in jail time, hefty fines, probation, and a permanent criminal record. In many cases, a conviction can also affect employment, housing, and educational opportunities.

TYPES OF POSSESSION
In drug cases, the location of the drugs is critical. There are several legal distinctions in possession cases, and understanding the differences is key to understanding what you’re up against.
Actual Possession
This occurs when the substance is found directly on your person—such as in your pocket, bag, or hand. It’s the most straightforward type of possession, but even these cases may involve questions about how the search was conducted or whether the item was truly yours.
Constructive Possession
Constructive possession means the drugs weren’t found on your person, but you had the power and intent to control them. For example, if drugs are found in your vehicle or home, you might still be charged with possession even if they weren’t physically on you. These cases often hinge on whether the prosecution can prove you knew about the drugs and had control over them.
Joint Possession
Joint possession applies when two or more people share control or ownership of the drugs. This often arises in situations involving roommates, shared vehicles, or group settings. The prosecution must still prove that you had knowledge and control, which opens up avenues for defense.
Understanding the nuances between these types of possession can dramatically affect how the court handles your case and the defenses available to you. At The Hartley Law Firm, we carefully analyze the facts and circumstances in order to challenge the prosecutions case.
CONTROLLED SUBSTANCE CLASSIFICATIONS
Controlled substances are drugs and other compounds regulated by both state and federal laws. These substances are categorized into five distinct schedules based on their potential for abuse, accepted medical use, and risk of dependency. Understanding these classifications is essential, as the severity of your charges and penalties often depends on the type of substance involved.
Schedule I
These substances have a high potential for abuse and no accepted medical use in the United States. Possession of a Schedule I drug typically carries the harshest penalties.
Examples: Heroin, LSD, MDMA (Ecstasy), Psilocybin (magic mushrooms), and Cannabis (under federal law)
Schedule II
These drugs have a high potential for abuse. However, they also have certain medical benefits. Charges involving Schedule II substances can result in lengthy prison sentences and significant fines.
Examples: Cocaine, Methamphetamine, Oxycodone (OxyContin), Fentanyl, Adderall, Vicodin
Schedule III
These drugs have a moderate to low potential for physical and psychological dependence. Penalties may still be serious but are generally less severe than Schedules I or II.
Examples: Ketamine, anabolic steroids, testosterone, Tylenol with codeine
Schedule IV
Drugs in this category have a lower potential for abuse. Doctors regularly prescribe these drugs. However, unauthorized possession can still result in criminal charges.
Examples: Xanax, Valium, Ativan, Tramadol, Ambien
Schedule V
These are substances with the lowest potential for abuse, often containing limited quantities of certain narcotics.
Examples: Cough preparations with less than 200 milligrams of codeine per 100 milliliters, Lomotil, Motofen
COMMON CHARGES AND PENALTIES
Missouri takes drug possession seriously, and even a small amount of a controlled substance can result in criminal charges. Whether you’re facing a first-time offense or have prior convictions, it’s important to understand how Missouri law classifies drug possession and the potential penalties involved.
1. Possession of a Controlled Substance (Section 579.015 RSMo)
In Missouri, it is unlawful to knowingly possess a controlled substance unless it was lawfully obtained with a valid prescription. Most possession charges fall under this statute.
- General Rule: Possession of any controlled substance other than 35 grams or less of marijuana is a Class D felony.
- Penalties: Up to 7 years in prison and/or up to $10,000 in fines.
- Examples: Cocaine, methamphetamine, heroin, ecstasy, LSD, prescription drugs without a valid prescription.
2. Possession of an Imitation Controlled Substance (Section 579.078 RSMo)
Missouri also has a misdemeanor charge known as possession of an imitation controlled substance. It is unlawful to knowingly possess an imitation controlled substance.
- General Rule: Possession of an imitation controlled substance is a Class A Misdemeanor.
- Penalties: Up to a year in the county jail and/or a $2,000 fine.
- Example: Baking soda in a small baggie meant to look like cocaine.
DEFENSES AGAINST POSSESSION CHARGES
REMEMBER: a charge is not the same as a conviction. At our firm, we closely examine the facts of your case to identify legal weaknesses, violations of your rights, and opportunities for dismissal or reduction.
Here are some of the most common and effective legal defenses in Missouri drug possession cases:
1. Unlawful Search and Seizure
The Fourth Amendment protects you from illegal searches by law enforcement. So, if the police searched your person, car, or home without a warrant, probable cause, or valid consent, any evidence they found—including drugs—may be suppressed in court.
Example: Drugs found during a traffic stop without reasonable suspicion or probable cause.
2. Lack of Knowledge or Intent
Prosecutors must prove that you knowingly possessed the controlled substance. If you didn’t know the drugs were in your car, bag, or home, you may have a valid defense.
Example: A friend left drugs in your vehicle without your knowledge.
3. Constructive vs. Actual Possession
Missouri law allows for “constructive possession,” meaning you had control or access to the area where drugs were found—but this is often a gray area. If the drugs weren’t found directly on you and multiple people had access to the space, your attorney can argue the drugs weren’t yours.
Example: Drugs found in a shared apartment or vehicle.
4. Valid Prescription
If you were arrested for possessing a prescription medication such as Adderall, Oxycodone, or Xanax, a valid prescription can be used to justify lawful possession, even if you didn’t have the medication in the original container.
5. Entrapment
If law enforcement pressured or coerced you into possessing or purchasing drugs—particularly in undercover operations—your attorney may be able to raise an entrapment defense. This defense is most common in cases involving confidential informants or undercover stings.
6. Lab Errors or Improper Testing
The prosecution must prove the substance was an illegal drug through laboratory testing. Mistakes in handling, storing, or testing the evidence can raise reasonable doubt about what the substance actually was.
7. Chain of Custody Issues
The prosecution must establish a clear chain of custody for the alleged drugs. If there are gaps or inconsistencies in how the evidence was handled from arrest to trial, your attorney may argue that the evidence is unreliable or inadmissible.

FREQUENTLY ASKED QUESTIONS
What is drug court and do I qualify?
Drug court is a treatment-focused alternative to jail, available in many Missouri counties for non-violent drug offenders. If accepted, you’ll undergo treatment and supervision instead of serving prison time. Successful completion can result in charges being dropped or reduced.
What if the drugs weren't mine?
This is a common situation. Missouri law requires the state to prove that you knowingly possessed the drugs. If the drugs were found in a shared car, house, or other space, we may be able to argue constructive possession does not apply—or that you had no knowledge or control over the substance.
I'm charged with possession of marijuana in Kansas, do I still need a lawyer?
Yes. Even a misdemeanor drug conviction can result in a permanent criminal record, affecting your employment, housing, and financial aid. An experienced defense attorney can help you fight the charge or seek alternatives like dismissal or diversion.
Can I go to jail/prison for a first time drug offense?
Yes, but jail time is not guaranteed—especially for first-time offenders. Many people are eligible for probation, drug court, or treatment programs instead of incarceration. A strong legal defense can significantly increase your chances of avoiding jail.
