Indiana

Overview

Indiana has no medical or adult-use cannabis program. Possessing less than 30 grams of marijuana is a Class B misdemeanor, and prior convictions or larger amounts raise the charge. CBD products made from hemp are legal under state law with labeling requirements. Indiana borders Illinois, Michigan, and Ohio, which all have legal markets, but bringing cannabis bought there into Indiana is illegal. Medical cannabis bills are introduced regularly but have not passed.

Driving and Cannabis

Driving while impaired by cannabis is illegal in Indiana, as it is in every state, whether or not the cannabis was obtained legally. Officers may rely on field sobriety tests, drug recognition evaluations, and blood tests, and some states set specific THC limits or zero-tolerance rules. Consuming cannabis in a vehicle and carrying open or unsealed packages where the driver can reach them are commonly prohibited. If you have used cannabis, the safest choice is not to drive.

Crossing State Lines and Federal Law

Taking marijuana across state lines is illegal under federal law, even between two states where cannabis is legal, and it may also violate the law of the state you enter. Marijuana is also prohibited on federal land, in national parks, and at airports under TSA jurisdiction. In 2026 the federal government moved FDA-approved products and state-licensed medical marijuana to Schedule III, but adult-use marijuana remains a Schedule I substance, and rescheduling does not legalize interstate transport. Separate federal changes to the legal definition of hemp take effect in late 2026 and will restrict many intoxicating hemp-derived THC products.
