Des Moines Marijuana Defense Lawyer

Iowa Marijuana Charges Handled by a Former Private Investigator

Iowa hasn’t decriminalized marijuana. While neighboring states like Illinois, Minnesota, and Missouri have legalized adult-use cannabis, possession of any amount in Iowa carries criminal penalties. Prosecutors enforce that line aggressively. A first-offense misdemeanor carries a mandatory 48-hour minimum jail sentence, one of the stricter first-offense penalties in the country.

Feld Law Firm represents Des Moines and Polk County residents charged with marijuana possession, manufacture, and distribution. Our attorney’s prior background as a private investigator shapes how we approach every case: investigating the facts, scrutinizing how evidence was gathered, and identifying weaknesses in the state’s case before trial. Services start at $1,000, and we offer Spanish-speaking support so every client can communicate clearly and confidently throughout the process.

Marijuana Laws in Iowa

Marijuana is a Schedule I controlled substance under the Iowa Controlled Substances Act. Possession for personal use is a misdemeanor, but the law covers a wide range of conduct with very different consequences.

• Possession with intent to distribute is a felony that can carry substantial prison time. Penalties increase significantly if the drug is sold to a minor.
• Cultivating or growing marijuana in Iowa is illegal and subject to felony charges.
• Possession of marijuana paraphernalia, such as bongs or pipes, is prohibited under Iowa law.

Types of Possession in Iowa

Iowa law recognizes two types of possession: actual and constructive.

Actual possession means the marijuana is physically on the person: in a pocket, a shoe, or a bag they’re carrying.

To prove constructive possession, the state must show you:

• Knew what the substance was
• Knew where it was
• Could exercise dominion and control over it

When marijuana is found in a shared space, proving which individual possessed it becomes much harder for the state. If prosecutors can’t establish all three elements beyond a reasonable doubt, you aren’t guilty of possession.

Marijuana Possession Penalties in Iowa

Penalties increase with each offense and vary depending on whether prior charges involved marijuana or another controlled substance.

First Offense

A first-offense possession charge carries fines up to $1,000 and up to six months in jail, with a mandatory 48-hour minimum. Probation may substitute for that minimum, but it isn’t guaranteed. A conviction can also disqualify or limit federal student loan eligibility for anyone enrolled at a college or university.

A substance abuse evaluation is required for first-offense charges. In some Iowa counties, failing to complete it before arraignment results in jail time assessed entirely to the defendant, so complete the evaluation before your court date. Additional fees include a $125 Law Enforcement Initiative Fee and a $10 D.A.R.E. surcharge. As of July 1, 2018, Iowa no longer suspends driver’s licenses for drug possession convictions unrelated to driving.

Second-Offense Possession of Marijuana

If the prior offense was also for marijuana, a second possession charge is a serious misdemeanor carrying fines up to $2,560 and up to one year in prison. It can also be used as an enhancement for any future possession charge. If the prior offense involved a different controlled substance, the second charge escalates to an aggravated misdemeanor. See our page on other controlled substance possession for details on how prior non-marijuana convictions affect future charges.

Third-Offense Possession of Marijuana

A third offense is an aggravated misdemeanor when both prior offenses were for marijuana, carrying fines up to $8,540 plus a 15% surcharge and $100 in court costs, and up to two years in prison. If either prior offense involved a different controlled substance, this charge becomes a Class D felony punishable by up to five years in prison and a $10,245 fine.

Consequences Beyond the Courtroom

Iowa hasn’t passed any decriminalization legislation. As of 2025, all marijuana possession without a valid medical cannabidiol registration remains a criminal offense. A conviction stays on your permanent record and can affect employment background checks, housing applications, and child custody proceedings. We counsel clients on how a conviction can affect student loan eligibility and long-term employment prospects. If your constitutional rights were violated during a stop or search, we can pursue dismissal on that basis. But an unlawful search doesn’t disappear on its own. It has to be challenged.

Possession with Intent to Distribute

To convict on possession with intent to distribute, the state must prove beyond a reasonable doubt that you possessed the marijuana and intended to distribute it.

To prove intent, the state will look to facts such as:

• Whether a scale was found near the drugs
• Whether the marijuana was packaged in individual baggies
• The quantity of marijuana
• Whether it was organized by type
• Where it was located

Prosecutors frequently add a failure-to-affix charge alongside an intent-to-distribute count. Under Iowa’s drug tax stamp law, failing to affix the required stamp is itself a Class D felony. The state must prove the person had at least 42.5 grams of marijuana without one.

Penalties for possession with intent to distribute:

• Less than 50 kg: Special Class D felony; fine of $1,000–$7,500 and up to 5 years.
• 50 to 100 kg: Special Class C felony; fine of $1,000–$50,000 and up to 10 years.
• 100 to 1,000 kg: Special Class B felony; fine of $5,000–$100,000 and up to 25 years.
• More than 1,000 kg: Special Class B felony; fine up to $1,000,000 and up to 50 years.

Penalties are enhanced if you were in immediate possession of a firearm at the time of arrest or if distribution occurred within 1,000 feet of a school zone.

How We Defend Marijuana Charges in Des Moines

A marijuana charge doesn’t mean the state’s case is airtight. Our attorney’s background as a private investigator means we approach every case with an investigator’s eye, not just a litigator’s. We examine how evidence was collected, how the stop was initiated, and whether law enforcement followed proper procedure at every step.

Challenging the Search

Police must have probable cause to search a person or vehicle. A warrantless search without valid consent or an applicable exception may be challenged through a motion to suppress. If the court grants that motion and excludes the marijuana evidence, the prosecution may not have enough to proceed and charges may be dropped. These motions require precise legal argument grounded in the specific facts of your stop.

Challenging Constructive Possession

When marijuana is found in a shared space, the state has to prove you specifically knew about it and controlled it. That’s often harder than it looks. We examine who else had access, what the facts actually show, and whether the prosecution can meet its burden on every required element.

Diversion & Deferred Judgment

First-offense defendants may be eligible for pretrial diversion; successful completion can result in dismissal of the charge. A deferred judgment is another option: the court defers sentencing, the defendant completes probation, and no conviction is entered on the record. Iowa law limits defendants to two deferred judgments in their lifetime, so how you use that option matters. We’ve handled hundreds of cases and can give you a realistic read on which options may apply to your situation.

Driving with Marijuana in the Vehicle

It happens more than people expect: someone is pulled over with marijuana in the vehicle and ends up facing more than a possession charge. Iowa law prohibits operating a motor vehicle with any detectable controlled substance in your system, and there is no measurable THC threshold the way there is for alcohol. Driving under the influence of cannabis carries the same penalties as alcohol-related operating while intoxicated (OWI).

Whether to add an OWI charge is at the officer’s discretion. Someone who volunteers that they smoked earlier in the day is generally charged. Don’t share information about prior marijuana use with law enforcement.

Why Des Moines Clients Choose Feld Law Firm

We bring a specific set of capabilities to marijuana defense that many firms don’t offer.

We offer Spanish-speaking support so clients from diverse backgrounds can communicate fully throughout the process. With services starting at $1,000, experienced representation in a marijuana case is more accessible than most people assume.

We treat every client as an individual. The defense we build for you is based on the specific facts of your case, not a template. We’ve handled hundreds of cases and can give you an honest, informed perspective on what options may be realistically available.
