No. Marijuana is not legal in Indiana for any purpose. The state has no medical cannabis program, no recreational market, and no exception that lets a doctor authorize cannabis for a patient. Possession of any amount is a criminal offense that can put you in jail, and the rule applies whether the marijuana came from a legal dispensary in Michigan, Illinois, or Ohio or from anywhere else.
Any cannabis plant material or product that exceeds 0.3% Delta-9 THC on a dry weight basis is treated as illegal marijuana under Indiana law. Indiana is one of roughly a dozen states with no effective medical cannabis law and one of fewer than twenty that still impose jail time for a first-time simple possession offense.
Possession Penalties by Amount
Indiana grades marijuana possession on an escalating scale. The trigger for the higher tiers is not a prior marijuana conviction specifically. Any earlier drug-related conviction counts.1Indiana General Assembly. Indiana Code 35-48-4-11 – Possession of Marijuana, Hash Oil, Hashish, or Salvia
- Any amount, no prior drug conviction: Class B misdemeanor, up to 180 days in jail and a fine up to $1,000.
- Less than 30 grams with a prior drug conviction: Class A misdemeanor, up to one year in jail and a fine up to $5,000.
- 30 grams or more with a prior drug conviction: Level 6 felony, six months to two and a half years in prison and a fine up to $10,000.
Cultivation falls under the same statute. Growing cannabis plants, or knowingly letting marijuana grow on your property without destroying it, carries the same penalties as possessing the equivalent amount.1Indiana General Assembly. Indiana Code 35-48-4-11 – Possession of Marijuana, Hash Oil, Hashish, or Salvia
Selling, delivering, or possessing marijuana with intent to deliver is a separate and more serious charge that escalates quickly with quantity, starting at a Class A misdemeanor and reaching a Level 5 felony at ten pounds or more.2Indiana General Assembly. Indiana Code 35-48-4-10 – Dealing in Marijuana, Hash Oil, Hashish, or Salvia
Paraphernalia Charges
Paraphernalia is usually charged alongside possession. Knowingly possessing any device you intend to use to consume, test, or enhance the effect of a controlled substance is a Class C misdemeanor, punishable by up to 60 days in jail and a fine up to $500. A prior paraphernalia conviction lifts the charge to a Class A misdemeanor with up to a year in jail and a fine up to $5,000.3Indiana General Assembly. Indiana Code 35-48-4-8.3 – Possession of Paraphernalia
Pipes, bongs, and concentrate vaporizers can all be charged as paraphernalia if a prosecutor can show intent to use them with a controlled substance. The statute carves out rolling papers and drug-detection items such as field test kits and fentanyl test strips.
Driving After Using Marijuana
Indiana’s Operating While Intoxicated law is zero-tolerance for cannabis. Driving with any detectable amount of a Schedule I or II controlled substance, or its metabolite, in your blood is a Class C misdemeanor, whether or not you are actually impaired at the wheel.4Indiana General Assembly. Indiana Code 9-30-5-1 – Operating While Intoxicated
This matters because THC metabolites are inactive compounds that can stay in your blood for days or weeks after your last use. Someone who used cannabis legally in Michigan on a Saturday can be charged with OWI driving through Indiana the following Wednesday while feeling completely fine.
A first-offense conviction can result in a license suspension of up to two years. Courts may instead order a minimum 30-day suspension followed by a 180-day probationary period restricted to driving for work.5Criminal Justice Institute. Impaired Driving Laws Fines and jail time are also on the table.
The Narrow Metabolite Defense
Indiana law gives you a statutory defense specifically for marijuana metabolite cases, but every one of these must be true: the substance detected was marijuana or its metabolite; you were not intoxicated at the time; you did not cause an accident; and the substance was identified through a chemical test administered under implied consent.4Indiana General Assembly. Indiana Code 9-30-5-1 – Operating While Intoxicated Cause a minor fender-bender and the defense is gone.
A separate warning for commercial drivers: federal DOT rules test for marijuana, and a positive result can disqualify a CDL regardless of where the use occurred, because marijuana is still illegal under federal law.6Federal Motor Carrier Safety Administration. What Substances Are Tested – What CDL Drivers Need to Know
Hemp CBD and the Delta-8 Problem
Hemp is the one place Indiana has loosened up. Senate Enrolled Act 52, signed by Governor Eric Holcomb in 2018, made it legal to sell, buy, and possess CBD oil derived from industrial hemp, provided the product contains no more than 0.3% Delta-9 THC and meets state labeling and testing rules. A retailer who knowingly sells actual marijuana packaged to look like a legal hemp extract faces a Level 5 felony dealing charge.
Delta-8 THC is a different story. Products are widely sold in Indiana stores, but Attorney General Todd Rokita’s Official Opinion 2023-1 declared that Delta-8 qualifies as a Schedule I controlled substance under Indiana Code 35-48-2-4(d)(31), reasoning that all natural and synthetic forms of THC are Schedule I and that Delta-8 does not fit any of the state’s named hemp exceptions.7Indiana Attorney General. Official Opinion 2023-1 Industry groups sued, and the legal status remains actively disputed. In practical terms, law enforcement may seize Delta-8 products and pursue charges based on the AG’s interpretation, so possession is not risk-free just because the product is on a store shelf.
Consequences Beyond the Criminal Case
A marijuana conviction, or even documented use, can reach into parts of your life that have nothing to do with criminal court.
Firearms
Federal law bars anyone who is an “unlawful user of or addicted to any controlled substance” from possessing a firearm or ammunition.8Office of the Law Revision Counsel. 18 US Code 922 – Unlawful Acts Because marijuana is still Schedule I federally, a regular user is prohibited from buying or possessing guns even without a conviction. The ATF background check form asks directly about controlled substance use, and lying on it is a federal felony.
Federally Assisted Housing
Federal regulations require housing providers to deny admission to anyone currently using illegal drugs, and drug-related criminal activity by a household member on or near the premises is grounds to evict the whole family. After an eviction for drug-related activity, re-admission is barred for at least three years unless you complete an approved rehabilitation program or the underlying circumstances no longer exist.9eCFR. Subpart I – Preventing Crime in Federally Assisted Housing
Federal Property in Indiana
Military installations, national forests, and federal courthouses are governed by federal law, not state law. A first federal possession offense carries up to one year in prison and a minimum $1,000 fine. A second offense: 15 days to two years and a minimum $2,500 fine. Third or later: 90 days to three years and a minimum $5,000 fine. Civil penalties of up to $10,000 can also apply separately.10Office of the Law Revision Counsel. 21 US Code 844 – Penalties for Simple Possession
What Might Change
The DEA and FDA proposed rescheduling marijuana from Schedule I to Schedule III in 2024, with a public comment period that closed in July of that year. As of early 2026, final action has not been taken.11Congress.gov. Legal Consequences of Rescheduling Marijuana Even if rescheduling is finalized, Schedule III does not legalize recreational use and would not override Indiana’s prohibition. It would mainly affect federal research restrictions and business taxation.
At the state level, cannabis reform bills appear in the Indiana General Assembly each session, ranging from medical programs to full adult-use legalization. So far they have not advanced out of committee. Until that changes, the practical answer for anyone living in or driving through Indiana is the one at the top of this page: marijuana is illegal, and enforcement carries real consequences.
