How Do Edible and THC Limits Work in Ohio?
Understanding “Equivalent THC Amounts”
Ohio calculates edible and infused product possession limits based on total THC content, not the physical weight of the product. This means a small edible with high THC concentration may count the same as a larger edible with lower THC levels.
Because THC content varies widely between products, edibles can be easier to exceed legal limits without realizing it.
What Happens If You Exceed Ohio’s Legal Limits?
Penalties for Possessing Too Much Cannabis
Possessing more than Ohio’s legal cannabis limits may result in:
Fines
Confiscation of cannabis
Possible misdemeanor charges, depending on the amount
Legalization does not eliminate penalties for over-possession, especially in cases involving distribution or repeat offenses.
Can You Carry Cannabis in a Vehicle in Ohio?
Ohio Cannabis Transportation Rules
Cannabis may be transported within Ohio only if it was legally purchased and remains sealed. Use of cannabis in vehicles is illegal for both drivers and passengers.
While sealed cannabis is legal to transport, having open or accessible cannabis in a vehicle may increase the risk of citations or DUI investigation — even if the driver is not impaired.
Crossing state lines with cannabis remains illegal under federal law.
