Is marijuana legal in Kansas?

Current legality status


Cannabis is illegal under state law.

Marijuana is not legal in Kansas. Both medical and recreational use is prohibited. CBD oil containing less than 5% THC is legal for people with certain debilitating medical conditions. Federally, over-the-counter CBD must have less than 0.3% THC. Producers who process the industrial hemp necessary to distill CBD must obtain a license.

The penalties for marijuana possession in Kansas are steep. Possession of marijuana for personal use, generally thought to be less than 25 grams, may result in misdemeanor convictions on the first and second offenses. 


  • First offense: $1,000 fine and a maximum prison sentence of six months
  • Second offense: $2,500 fine and a maximum prison sentence of a year
  • Third offense: felony, fines up to $100,000 and up to 3.5 years in jail

Distribution penalties are draconian as well. Intent to distribute less than 25 grams is a felony and may result in up to 51 months in prison and fines of up to $300,000. 

Larger amounts result in even more stringent sentencing, with penalties topping out at 17 years in jail and $500,000 in fines. 

Similarly, cultivation penalties go up with the number of plants, with as few as five plants resulting in a felony conviction, up to seven years in jail, and a maximum fine of $300,000.

Kansas’ strict marijuana laws resulted in the arrest of 5,608 people in 2016.

Kansas recreational & medical marijuana legalization efforts

Kansas recreational and medical legalization efforts are slow going. Changing the law requires an act of the legislature, which meets once a year for a maximum of 90 days in even-numbered years and for a period of unlimited duration in odd-numbered years. The state does not have a ballot initiative procedure.

A bill to legalize medical marijuana in Kansas (HB 2017) was introduced in the House in June 2020, but died in the Committee on Federal and State Affairs within a day, having been introduced during a brief special session. 

In October 2019, that committee issued recommendations for a medical marijuana program that would exclude unrefined plant products and vaping. The committee also suggested that medical marijuana cardholders from other states found in possession of cannabis products should not be prosecuted.

Legislation in 2016 (HB 2462) and 2017 (SB 112) reduced penalties for possession.

Legislation (SB 9, HB 2011) to establish a medical marijuana program introduced in 2015 died in committee. A number of previous attempts have failed over the years as well. Legislation passed in 2018 (SB 282) legalized the sale and use of CBD.

Governor Laura Kelly (D) has stated that she would like to ratify a medical marijuana bill and would likely support legalization of recreational marijuana as well. US Representatives Roger Marshall (R) and Ron Estes (R), incumbents in the 2020 election, have stated their opposition to recreational legalization. Both Republican US senators are also against legalization.

A 2019 survey found that 63.1% of Kansas residents supported legalizing recreational marijuana.
