Arrested or Charged with Trafficking Drugs in the First Degree (RSMo § 579.065) in Missouri?

A charge for Trafficking Drugs in the First Degree in Missouri under RSMo § 579.065 is among the most serious drug offenses in the state. This statute covers large-quantity drug cases involving substances like heroin, cocaine, methamphetamine, marijuana, and fentanyl—and it doesn’t take much to trigger the charge.

If you were arrested and accused of trafficking, your future may feel uncertain. And you may have questions like:

• What is the threshold for a trafficking charge?
• Does this mean I’m going to prison?
• Can the charge be reduced or resolved without going to trial?
• How can an attorney actually help?

At Rose Legal Services, we focus entirely on criminal defense — and drug charges like this are a large part of our work. We’ve helped thousands of clients across Missouri, including those charged with serious felonies. Our team knows how to analyze these cases, ask the right questions, and work toward the best outcome possible.

What Counts as First-Degree Drug Trafficking Under Missouri Law?

Under RSMo § 579.065, you can be charged with Trafficking Drugs in the First Degree if you knowingly do any of the following involving a large quantity of certain controlled substances:

• Distribute
• Deliver
• Manufacture
• Produce
• Or attempt to do any of the above

The statute is based on drug quantity, not whether you sold drugs or profited from them. If you had more than a specific weight of certain drugs, Missouri law assumes the purpose was trafficking—even if no sale occurred.

When Does It Count as First-Degree Trafficking?

Here are examples of thresholds that can lead to a first-degree trafficking charge:

• Heroin: More than 30 grams
• Cocaine: More than 150 grams
• LSD: More than 500 milligrams
• PCP: More than 30 grams or 4 grams pure
• Marijuana: More than 30 kilograms
• Methamphetamine, Amphetamine, or Similar Stimulants: More than 30 grams
• MDMA (Ecstasy): More than 30 grams
• Fentanyl or Carfentanil: More than 10 milligrams
• Flunitrazepam (Rohypnol): 1 gram or more
• GHB (Gamma-Hydroxybutyric Acid): Any amount

Some substances, like GHB or flunitrazepam (Rohypnol), trigger first-degree trafficking charges regardless of quantity or with much smaller amounts due to their classification under Schedule I or II.

Keep in mind: You can also be charged under this statute for attempting to deliver or manufacture one of these substances, even if the process wasn’t completed.

Penalties for Trafficking Drugs in the First Degree in Missouri

Class B Felony: Standard Penalty

Most first-degree trafficking charges begin as a Class B felony, which carries:

• 5 to 15 years in prison
• Possible denial of probation or parole, depending on the facts

This level applies when the quantity is above the minimum threshold, but not at the extreme levels outlined in the statute.

Class A Felony: Aggravated Circumstances or Higher Quantities

Your charge can be upgraded to a Class A felony if:

• The quantity of drugs is extremely high
• The offense occurs near a school, on public housing property, in a hotel, or on a school bus
• You are accused of trafficking fentanyl in excess of 20 milligrams
• This is a repeat offense

Class A felony penalties include:

• 10 to 30 years in prison, or
• Life imprisonment
• In many cases, no eligibility for probation or parole

Examples of What Can Lead to a First-Degree Trafficking Charge

Many people are shocked to learn how little it takes to be charged with a serious felony in Missouri:

• A person pulled over with just over 30 grams of heroin may face a Class B felony
• A stash of marijuana weighing 35 kilograms in a car or storage unit may qualify as first-degree trafficking
• A backpack with 12 grams of PCP or 500+ pills of ecstasy may trigger Class A felony prosecution

How Does This Differ from Possession or Delivery?

While Missouri law recognizes a separate offense for Delivery of a Controlled Substance (RSMo § 579.020), the distinction here is mostly about quantity. You don’t have to sell, trade, or hand off the drugs to face a trafficking charge.

And while possession with intent charges usually rely on circumstantial evidence like packaging or cash, trafficking charges are triggered automatically by the drug weight alone.

You can be charged with trafficking even if:

• You were the only person in the car or home
• You never handed the drugs to another person
• You didn’t know the exact weight of what you had

Defenses We Explore in First-Degree Drug Trafficking Cases

At Rose Legal Services, we understand how these cases are investigated and prosecuted, and we know how to look deeper. Depending on your case, we may:

Challenge the Legality of the Stop, Search, or Arrest

• Was there probable cause for the traffic stop or warrant?
• Was the search done lawfully?
• Was evidence seized properly and logged correctly?

Illegal searches are one of the most common issues in drug trafficking cases—and they may result in suppression of evidence.

Dispute the Quantity or Purity of the Drug

• Was the substance tested accurately?
• Were weights from multiple bags or types improperly added together?
• Was the lab analysis done according to chain of custody requirements?

We often work with independent experts to analyze whether the state’s evidence holds up.

Review Any Location-Based Enhancements

The Class A upgrade often depends on where the offense allegedly took place. We investigate:

• Was the location actually within 2,000 feet of a school or public housing?
• Did law enforcement measure correctly?
• Was the area clearly posted or defined as “school property”?

What Should You Do After a First-Degree Trafficking Arrest?

You should not speak to police, detectives, or investigators without a criminal defense attorney. Anything you say may be used against you. Call an experienced defense team who understands how Missouri’s drug laws work and how prosecutors build these cases.
