Missouri’s legalization of recreational marijuana has created a LOT of confusion. People think all marijuana charges disappeared overnight — but that’s not true. Many drug laws did change, but several remained just as strict as before.

And because police, prosecutors, and the public are still adjusting, many Kansas City residents are finding themselves charged with crimes they never expected.

At KC Defense Counsel, we know everyone has questions and we’ve had a lot of potential clients asking the same questions you’ve got running through your mind — and our experienced Missouri drug defense lawyers can help you to understand exactly what you need to know about Missouri’s post-legalization drug laws.

1. Is possession of marijuana completely legal now in Missouri?

Not completely — just mostly. Adults over 21 can possess up to 3 ounces of marijuana legally. Anything above that amount is still a crime. For example:

3–10 ounces = civil violation + fine
Over 10 ounces = misdemeanor or felony, depending on the amount
Large amounts can still be charged as intent to distribute

A lot of people get charged because they don’t understand the new possession limits. If you’re caught with more than the legal amount — even slightly more — you can still be arrested.

2. Can I grow marijuana at home now?

Yes — but only with a cultivation card, and even then, there are strict rules. Cardholders may grow up to:

6 flowering plants
6 non-flowering plants
6 seedlings

BUT if you grow without a card — or have more than the legal number — you can face felony cultivation charges, even though recreational marijuana is legal.

Police still investigate illegal grow operations aggressively, and many people get charged because they misunderstood the rules.

3. Can I carry or use marijuana in public now?

No. Public consumption is still illegal. That includes:

Parks
Sidewalks
Parking lots
Restaurants
Cars
Bars
Concert venues
Sporting events

You can still receive citations or misdemeanor charges for marijuana use in public places. Marijuana is legal — but public use is not.

4. Can I get a DUI for marijuana in Missouri?

Yes — absolutely. Marijuana DUIs are now one of the fastest-growing charges in Kansas City. Missouri police test for impairment using:

Roadside evaluations
Officer testimony
Statements
Blood testing (in some cases)

You do not have to be above a specific THC limit. If an officer believes you were impaired, you can be charged.

Marijuana legalization has not changed DUI laws — and prosecutors still take these cases very seriously.

5. Did legalization erase old marijuana charges from my record?

Many people think their old marijuana convictions disappeared — but not automatically. Some non-violent marijuana convictions are eligible for:

Expungement
Record sealing
Reduced charges
Complete dismissal in some cases

But you still have to apply. A skilled Kansas City criminal defense attorney can determine if your case qualifies and file for an expungement so your past doesn’t haunt your future.

6. If marijuana is legal now, are other drug charges treated differently too?

No — and this is where people get into trouble. Legal marijuana does not change the laws for:

Cocaine
Heroin
Methamphetamine
Fentanyl
Prescription pills without a script
MDMA
LSD and other controlled substances

Possession, distribution, and trafficking charges for these drugs remain extremely serious felonies in Missouri — and legalization of marijuana has not softened the penalties for anything else.

7. Can the police still search my car if they smell marijuana?

This is the biggest question clients ask — and yes, they can… sometimes.

Missouri courts have been inconsistent since legalization. Some judges say the smell of marijuana is no longer probable cause, others say officers can still search if they feel there’s evidence of a crime.

Police may argue:

You’re over the 3-ounce limit
You’re impaired
There are drugs besides marijuana
There is evidence of distribution

An illegal search may be challenged in court, and an attorney can move to suppress the evidence if the search violated your rights.
