What Indiana law says about THCA

Indiana is one of the clearest states on THCA flower. Under IC 35-48-4-10.1, anyone who knowingly manufactures, delivers, finances or possesses smokable hemp commits a Class A misdemeanour; the only exception covers shipments passing through Indiana between licensed businesses.¹ Smokable hemp means hemp in a form that lets THC be inhaled as smoke, and expressly includes hemp bud and flower.²

THCA also counts in Indiana’s extract rules. A legal low THC hemp extract may contain no more than 0.3% total delta-9 THC including precursors, which captures THCA, and the definition excludes the flower of the female plant and smokable hemp.³ A concentrate or edible marketed for high THCA content will usually exceed that limit and can be treated as marijuana.

The smokable hemp ban was challenged in federal court. In July 2020 the Seventh Circuit set aside an injunction that had blocked it, and the ban has been enforceable since.⁴ Legislative efforts in 2025 and 2026 to create a regulated hemp market did not pass, and retail sale of hemp flower remains the clearest hemp offence in Indiana.⁵

Pending changes to watch

No state bill is pending; the 2026 session ended without changes to the smokable hemp ban.

How the federal hemp change affects Indiana

Separate from Indiana law, the federal definition of hemp is changing. Under the federal hemp redefinition passed in the FY2026 appropriations law, from 11 December 2026 hemp is measured by total THC, which counts THCA as well as delta-9 THC, and finished products are capped at 0.4 mg of total THC per container. High-THCA flower sold as hemp today will not meet that definition, so from that date it is treated as marijuana under federal law, whatever state law says.

Bills to delay or repeal the change are in congressional committees, but none had advanced as of September 2026. Our explainer on the federal hemp THC limit covers the detail, and THCA vs delta-9 THC explains why heat turns THCA into delta-9.

Timeline of recent changes

• February 2026: SB 250 dies; the smokable hemp ban and total delta-9 extract limit stay in place.
• 8 July 2020: Seventh Circuit vacates the injunction against Indiana’s smokable hemp ban in C.Y. Wholesale v. Holcomb.

THCA in neighbouring states

Rules change at the state line. Here is how THCA is treated in the states bordering Indiana, as of September 2026:

• Illinois: 21+; hemp sales end 12 Nov 2026
• Michigan: Licensed marijuana stores only, 21+
• Ohio: Dispensary only, 21+
• Kentucky: Flower and high-THCA sales banned

Carrying products across state lines can break the law of the state you enter, and federal law also applies. Check the destination state’s rules first.

Delta-8 in Indiana

Delta-8 is treated differently: in Indiana it is Unclear: AG says illegal as of September 2026. Read our guide to Delta-8 law in Indiana, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

Is THCA flower legal in Indiana?

No. Indiana law makes it a Class A misdemeanour to manufacture, deliver or possess smokable hemp, and the definition expressly includes hemp bud and flower. That covers THCA flower and pre-rolls even when they meet the federal delta-9 THC limit.

Are THCA edibles or concentrates legal in Indiana?

Only if they qualify as low THC hemp extract, meaning total delta-9 THC, counting THCA and other precursors, is no more than 0.3% by weight. That leaves little room for THCA, so products sold for high THCA content are unlikely to comply.

What is the penalty for THCA flower in Indiana?

Dealing in or possessing smokable hemp is a Class A misdemeanour, which in Indiana can mean up to one year in jail and a fine of up to $5,000. If the flower exceeds the hemp THC limit, marijuana charges could apply instead.
