There's a huge asterisks that goes with that claim. Although Kansas and Iowa both have non-THC CBD oil and are routinely cited as being legal states, possession is a misdemeanor carrying 6 months and/or $1000 fine in both states. Nebraska's first offense is $100 civil infraction. Nebraska is still more lenient for possession than these 23 states: AL, AR, FL, GA, ID, IN, IA, KS, KY, MO, MT, ND, NJ, OK, PA, SC, SD, TN, TX, VA, WV, WI, WY (NORML).
Some have asked about edibles in Nebraska, NORML says the penalty is a felony punishable by $10,000 and/or 5 years. Ouch!
