What Is Louisiana’s Uniform Controlled Dangerous Substances Law?

Louisiana’s Uniform Controlled Dangerous Substances Law is the state statute, codified in Title 40 of the Louisiana Revised Statutes beginning at Section 961, that classifies every regulated drug into one of five schedules and sets the criminal penalties for possessing, distributing, manufacturing, cultivating, or fraudulently obtaining those substances. Penalties scale with the schedule, the weight involved, the type of conduct, and where the offense took place. Many offenses carry mandatory minimums, and a conviction brings consequences that reach well past the courtroom.

The Five Schedules

Every regulated drug sits in one of five schedules under La. R.S. 40:964, ranked by addiction potential and whether the substance has an accepted medical use.¹

Schedule I: High addiction potential and no accepted medical use. Heroin, LSD, MDMA, psilocybin, and marijuana sit here.²
Schedule II: High addiction potential with a restricted medical use. Cocaine, methamphetamine, fentanyl, oxycodone, and amphetamine salts.
Schedule III: Lower addiction potential, accepted medical use. Anabolic steroids, ketamine, and certain limited-codeine combinations.
Schedule IV: Low addiction potential. Alprazolam, diazepam, and other benzodiazepines. Flunitrazepam (Rohypnol) is here but carries far heavier penalties than the rest of the schedule.
Schedule V: Lowest potential for abuse. Cough preparations with small amounts of codeine, certain anti-diarrheal medications.

Which schedule a substance occupies drives nearly every penalty in the drug code.

What the Law Prohibits

The statute criminalizes several distinct categories of conduct, and the line between them often decides whether a case is a short jail sentence or decades in prison.

Simple possession means knowingly having a controlled substance without a valid prescription. The drug does not have to be on your body. If prosecutors can show you knew about it and could control it, that is enough; pills in a locked glove compartment count even if you were standing outside the car when officers found them.

Possession with intent to distribute is proved mostly through circumstantial evidence: quantity, individual packaging, scales, large amounts of cash, messages about sales. Possessing 28 grams or more of a Schedule II substance is treated as a distribution offense automatically, regardless of other evidence.³

Distribution covers any transfer to another person, with or without payment. Handing a friend a prescription pill you were not authorized to share qualifies. Manufacturing covers producing or processing a substance by any method, from operating a meth lab to extracting concentrated THC. Cultivation covers growing drug-producing plants.

Prescription fraud is a separate crime under La. R.S. 40:971.⁴ Forging or altering a prescription, using a fake name at a pharmacy, and doctor shopping (getting a prescription from one provider without disclosing an existing one from another) are all prosecutable. So is helping falsify medical records.

Penalties by Schedule

Schedule I, General Substances

For distribution or possession with intent to distribute a Schedule I substance other than heroin or marijuana, penalties turn on weight:⁵

Less than 28 grams: one to ten years, with or without hard labor, and a fine up to $50,000.
28 grams or more: one to twenty years at hard labor and a fine up to $50,000.

Simple possession:

Less than 2 grams: up to two years and a fine up to $5,000.
2 grams to less than 28 grams: one to ten years and a fine up to $5,000.

Heroin

Distribution of any amount of heroin or its analogues carries five to forty years at hard labor and a fine up to $50,000.⁵ Simple possession of less than two grams carries two to four years, with a higher range once the weight reaches two grams.

Marijuana

Marijuana stays on Schedule I but carries a much lighter possession structure:

14 grams or less, any offense: a misdemeanor, maximum $100 fine, no jail time.
More than 14 grams, first offense: up to $500 and up to six months in jail.
More than 14 grams, second offense: up to $1,000 and up to six months.
More than 14 grams, third offense: up to $2,500 and up to two years.
More than 14 grams, fourth or subsequent offense: up to $5,000 and up to eight years.

Marijuana distribution follows the general Schedule I framework: less than 2.5 pounds brings one to ten years and a possible $50,000 fine; 2.5 pounds or more brings one to twenty years.

Schedule II

Simple possession:³

Less than 2 grams: up to two years and a fine up to $5,000.
2 grams to less than 28 grams: one to five years and a fine up to $5,000.
28 grams or more: charged as distribution.

Fentanyl and its analogues carry enhanced ranges within Schedule II. Possessing less than two grams brings a two-year mandatory minimum; two to twenty-eight grams brings two to ten years. Manufacturing methamphetamine or amphetamine carries ten to thirty years at hard labor, with at least ten years not reducible by parole, probation, or suspended sentence, plus a possible fine up to $500,000.

Schedules III, IV, and V

Schedule III distribution carries one to ten years and a fine up to $15,000; possession carries one to five years and up to $5,000. Schedule IV mirrors those ranges for most substances. Flunitrazepam is the exception: distribution carries one to twenty years at hard labor and a mandatory fine up to $50,000, and secretly administering any Schedule IV drug to someone in order to commit a violent crime carries five to forty years. Schedule V distribution and possession each carry one to five years and up to $5,000.

Enhancements That Raise the Sentence

Several circumstances enlarge the baseline penalty. A drug offense committed within 2,000 feet of a protected location under La. R.S. 40:981.3 results in the maximum fine for the underlying offense plus imprisonment of up to one and one-half times the longest term the offense would otherwise carry.⁶ Protected locations include school property, school buses, drug treatment facilities, religious buildings, public housing, and child daycare centers. Not knowing you were in the zone is not a defense; the statute removes that argument. In New Orleans and Baton Rouge, the overlapping radiuses cover much of entire neighborhoods.

Separate enhancements apply when an adult involves a minor in drug activity or distributes a controlled substance to anyone under eighteen.⁷

Drug Paraphernalia

Paraphernalia under La. R.S. 40:1021 through 40:1025 includes any equipment used to produce, process, inhale, inject, or consume a controlled substance: pipes, syringes, scales, mixing containers, and ordinary household items when context ties them to drug activity.⁸ General paraphernalia penalties escalate with each conviction:⁹

First offense: a fine up to $300, up to fifteen days in jail, or both.
Second offense: a fine up to $1,000, up to six months in jail, or both.
Third or subsequent offense: a fine up to $2,500, up to two years with or without hard labor, or both.

Marijuana paraphernalia for personal use follows a lighter track: $100 for a first offense, $500 for a second, $2,500 for a third or subsequent, and no jail at any level.

Where Medical Marijuana Fits

Louisiana runs a medical marijuana program under La. R.S. 40:1046 that creates a legal pathway for qualifying patients.¹⁰ An authorized clinician with a genuine clinical relationship with the patient may recommend marijuana for conditions including cancer, epilepsy, PTSD, Crohn’s disease, intractable pain, multiple sclerosis, Parkinson’s disease, and traumatic brain injury, and the statute includes a catch-all for any condition the clinician determines to be debilitating for that patient. Patients buy in person from a Louisiana-licensed retailer, and each retailer must offer monthly delivery in every zip code within its region. Purchases are capped at two and one-half ounces (71 grams) of raw marijuana every fourteen days. Employers and workers’ compensation insurers are not required to pay for medical marijuana even with a clinician’s recommendation.

Property the State Can Seize

Louisiana law allows the state to seize and forfeit property connected to drug offenses, including:¹¹

The controlled substances themselves.
Property furnished or intended to be furnished in exchange for a controlled substance.
Anything used or intended to facilitate a drug offense, including vehicles.
Money or other assets derived from drug activity.
Any weapon possessed, used, or available for use in connection with a drug offense.

Forfeiture proceeds separately from the criminal case. Property can be taken and lost even if the underlying charges are reduced or dismissed.

How Federal Law Fits In

Federal drug law does not override Louisiana’s statute. Under 21 U.S.C. § 903, Congress chose not to occupy the field, so both systems operate in parallel.¹² A single sale of methamphetamine can violate both. In practice, federal prosecutors concentrate on large-scale trafficking, cartel-connected operations, and cases involving firearms, leaving most street-level enforcement to Louisiana authorities. Federal rescheduling of marijuana does not change Louisiana’s classification of marijuana as Schedule I, and state penalties remain enforceable regardless of federal action.¹³

Consequences Beyond the Sentence

A conviction under this law brings more than the sentence a judge announces. A felony drug conviction disqualifies you from SNAP food assistance for one year from conviction or one year from release, whichever is later. Public housing authorities can ban you and your entire household, and the same rule reaches Section 8 vouchers. A drug conviction while receiving federal student financial aid costs you eligibility for a period set by federal law and requires immediate repayment of aid received after the conviction date.

A felony drug conviction can be grounds for termination and can disqualify you from professional licenses, government employment, and security clearances. Credentials like the Transportation Worker Identification Credential for port access are unavailable to anyone with a felony drug conviction within seven years of application. For noncitizens, even a minor drug plea can trigger deportation, and drug addiction alone is a ground for removal.

People whose marijuana-related conduct has since been decriminalized can seek expungement of prior convictions, which can clear some of these barriers.
