Minnesota Cannabis Possession Limits (2026)

Minnesota Statute 342.09(b) caps single-day cannabis purchases at one of three equivalents (or proportional combinations).

In public — outside a private residence — adults 21 or older may possess no more than the single-day purchase cap: 2 ounces flower, 8 grams concentrate, or 800 mg edible THC. This applies in vehicles, restaurants, retail establishments, public parks, and any non-residential setting.

At a private residence, the home-possession cap is 2 pounds (32 ounces / 907 grams) of cannabis flower. The 8-gram concentrate cap and 800-mg edible THC cap also apply at home in some interpretations; consult MN OCM rulemaking for nuance.

Adults 21 or older may cultivate up to 8 cannabis plants per residence for personal use — with a maximum of 4 plants flowering at any one time. Plants must be grown in a secure space not visible to the public and out of reach of minors. Cultivation for personal use is permitted regardless of whether other adults in the residence also cultivate; the cap is per residence, not per adult.

Every licensed Minnesota cannabis retailer — tribal and MN OCM-licensed — tracks customer purchases against the daily cap via METRC seed-to-sale software. A retailer cannot sell beyond the daily cap to the same individual. Multiple separate-day visits are tracked independently.

While Minnesota possession limits define what a customer may legally hold in-state, federal law preempts interstate transport regardless of state legality. Federal Controlled Substances Act (21 USC § 812) classifies cannabis as Schedule I and prohibits transport across state lines — even when both states have legalized recreational use.
