Delta-8 THC is not clearly legal in Indiana, and it is not clearly illegal either. The state’s Attorney General has taken the position that delta-8 is a Schedule I controlled substance, no Indiana court has ruled otherwise, and products remain widely sold on shelves. If you buy, possess, or sell delta-8 in Indiana today, you are operating in contested legal territory where a prosecutor who follows the Attorney General’s view could bring criminal charges. A federal law change scheduled for November 2026 will likely end the ambiguity by making most delta-8 products illegal outright.
Why the Legal Status Is Unsettled
Indiana adopted the federal hemp framework in 2019. State law defines hemp as the Cannabis sativa L. plant and all its derivatives, cannabinoids, and isomers, provided the delta-9 THC concentration stays at or below 0.3% by dry weight.1Indiana General Assembly. Indiana Code Title 15 – 15-15-13-6 Read literally, that definition covers delta-8, which is a cannabinoid and an isomer of the hemp plant.
A separate part of the criminal code cuts the other way. Indiana’s Schedule I list includes “tetrahydrocannabinols” as a broad category, covering derivatives of the substances in the cannabis plant and their isomers.2Indiana General Assembly. Indiana Code 35-48-2-4 – Schedule I Delta-8 is a tetrahydrocannabinol. So one statute appears to legalize it as a hemp derivative, and another appears to criminalize it as a scheduled drug.
The bridge is a narrow safe harbor called “low THC hemp extract.” To qualify, a product must be derived from hemp, contain no more than 0.3% delta-9 THC, and contain no other controlled substances.3Indiana General Assembly. Indiana Code 35-48-1.1-27 – Low THC Hemp Extract If delta-8 counts as a controlled substance under the Schedule I “tetrahydrocannabinols” listing, then any product containing it fails the “no other controlled substances” requirement and loses the safe harbor. That single interpretive question drives everything.
The Attorney General Says It Is a Schedule I Substance
On January 12, 2023, Indiana Attorney General Todd Rokita issued Official Opinion 2023-1 concluding that delta-8 THC and other THC variants are Schedule I controlled substances under state law. The reasoning: Schedule I covers tetrahydrocannabinols broadly, delta-8 is a tetrahydrocannabinol, and any product containing it therefore contains a controlled substance and cannot qualify as a low THC hemp extract.4Office of the Indiana Attorney General. Official Opinion 2023-1
The opinion also addressed federal law. The 2018 Farm Bill allows states to impose stricter hemp regulations than the federal government does, and the Attorney General relied on that provision to argue Indiana can classify delta-8 as a controlled substance even if it is federally legal.4Office of the Indiana Attorney General. Official Opinion 2023-1
An Attorney General opinion is not law. It does not bind courts, and it does not create criminal liability on its own. What it does is signal to prosecutors and police how the state’s top legal officer reads the statute. A local prosecutor who agrees can bring charges, and you would then have to fight the interpretation in court.
A Federal Court Did Not Resolve the Question
In March 2025, U.S. District Judge James Sweeney dismissed a lawsuit challenging the Attorney General’s opinion. His reasoning was that the opinion “is not binding and isn’t law,” so striking it down would not stop prosecutors from independently reaching the same conclusion about delta-8. The dismissal was without prejudice, and the judge noted that the question is “fundamentally” one for Indiana’s courts to decide. No Indiana state court has issued a definitive ruling on whether hemp-derived delta-8 is legal. Until one does, the status remains genuinely uncertain.
What You Could Be Charged With
If a prosecutor treats delta-8 as a Schedule I substance, the penalties depend on what you are doing with it and how much you have.
Possession
Indiana’s possession statute covers marijuana, hash oil, hashish, and salvia. Prosecutors commonly classify THC concentrates as hash oil. Under that framing, simple possession is a Class B misdemeanor carrying up to 180 days in jail. A prior drug conviction bumps the charge to a Class A misdemeanor with up to a year. Possession of five or more grams of hash oil with a prior drug conviction is a Level 6 felony, punishable by six months to two and a half years in prison.5Indiana General Assembly. Indiana Code 35-48-4-11 – Possession of Marijuana, Hash Oil, Hashish, or Salvia
Dealing
Selling or distributing a Schedule I substance is far more serious. The base offense is a Level 6 felony, and the charge escalates with quantity:6Indiana General Assembly. Indiana Code 35-48-4-2 – Dealing in a Schedule I, II, or III Controlled Substance
- Level 6 felony (base): six months to two and a half years.
- Level 5 felony (at least one gram, less than five): one to six years.
- Level 4 felony (at least five grams, less than ten): two to twelve years.
- Level 3 felony (at least ten grams, less than twenty-eight): three to sixteen years.
- Level 2 felony (twenty-eight grams or more): ten to thirty years.
Each level can escalate further if an enhancing circumstance applies, such as selling near a school or to a minor. For retailers with shelves of delta-8 cartridges, the dealing statute is the main source of criminal exposure.
Smokable Delta-8 Is Separately Banned
Even setting aside the Schedule I debate, Indiana bans smokable hemp outright. The state’s low THC hemp extract definition explicitly excludes smokable hemp and the reproductive parts of the female hemp plant.3Indiana General Assembly. Indiana Code 35-48-1.1-27 – Low THC Hemp Extract Delta-8 flower, pre-rolls, and any product designed to be inhaled as smoke are illegal in Indiana regardless of THC content and regardless of how the delta-8 question ultimately gets resolved.
Driving and Drug Testing
Indiana treats driving with any detectable Schedule I or II substance, or its metabolite, in your blood as a Class C misdemeanor.7Indiana General Assembly. Indiana Code Title 9 – 9-30-5-1 The statute includes a limited defense for marijuana metabolites when the driver was not actually impaired, did not cause an accident, and the substance was detected through a chemical test. That defense requires you to raise it in court; it does not prevent the arrest.
Delta-8 is chemically close enough to delta-9 that it triggers positive results on standard THC drug tests. Most employment screening panels do not distinguish between the two. A positive test can cost you a job offer, trigger termination under a workplace policy, or disqualify you from safety-sensitive work. Your employer’s drug policy operates independently of whatever Indiana courts eventually decide about legality.
No State Age Limit Under Current Law
Indiana currently has no state-mandated minimum age to buy hemp-derived delta-8 products. Most retailers voluntarily restrict sales to customers 21 and older, but that is a business decision, not a legal requirement. Senate Bill 478, introduced in the 2025 legislative session, would create a statewide 21-and-older requirement along with testing, packaging, and advertising rules for hemp-derived THC products.8Indiana General Assembly. Senate Bill 478 – Craft Hemp Flower and THC Products As of mid-2025, the bill remained in conference committee after the Senate dissented from House amendments, and passage was not guaranteed.
The Federal Change Coming in November 2026
Even if Indiana’s gray zone eventually resolves in favor of delta-8, the federal ground is shifting. In November 2025, Congress enacted P.L. 119-37, which rewrites the federal definition of hemp. The new law takes effect on November 12, 2026.9Congress.gov. Change to Federal Definition of Hemp and Implications for Federal Law
The core change is that the federal definition will use “total THC concentration” rather than only delta-9 THC, closing the loophole that made delta-8 products arguable under federal law. The new definition also explicitly excludes:
- Synthetically produced cannabinoids, meaning any cannabinoid that cannot be naturally produced by the cannabis plant or that was synthesized outside the plant even if it occurs naturally. Most commercial delta-8 is chemically converted from CBD in a lab, so this provision likely captures the bulk of the market.
- Products exceeding 0.4 milligrams of THC per container, a trace-level cap that would rule out virtually all delta-8 edibles, tinctures, and vape cartridges.
- Intermediate products with more than 0.3% total THC, targeting the concentrated hemp extracts used in manufacturing.9Congress.gov. Change to Federal Definition of Hemp and Implications for Federal Law
Once P.L. 119-37 takes effect, delta-8 products that currently occupy a federal gray area will lose any plausible claim to federal legality. For Indiana consumers and retailers, the window of ambiguity is closing. Products that are merely risky to sell today are on track to become unambiguously illegal under both state and federal law by the end of 2026. If you are making decisions about delta-8 in Indiana right now, plan around that timeline and around the fact that a prosecutor in your county may already treat these products as controlled substances.
