Medical Marijuana Law in Missouri Update

Missouri’s Medical Marijuana Program was approved on Nov 6, 2018. The program will be rolling out and patients can start applying for Identification Cards starting July 4, 2019. Possession of Medical Marijuana is still illegal until the state approves “a series of steps” so that patients who are issued Medical Marijuana Cards will not be prosecuted.


Some progress was made, in 2014, when the legislature approved changes to the state’s criminal code so possession of a small amount of weed — 10 grams or less — would only be punishable by a fine, not to exceed $500, rather than a jail sentence. However, the state still classifies this offense as a criminal misdemeanor, and possession of larger amounts of marijuana still result in jail time.

For example, if someone is convicted of possessing more than 10 but less than 35 grams of weed, they could face as much as a one-year jail sentence and a fine of up to $2,000. Under marijuana law in Missouri, if someone is convicted of a second offense, they will still face the same punishment even if the amount possessed was less than 10 grams.

Anyone convicted of possession of 35 grams to 30 kilograms of pot will face a Class C felony charge. This could lead to up to one year in jail and a fine of up to $5,000. Possession of from 30-100 kg of weed will be looking at five to 15 years in jail and a fine of anywhere from $5,000 to $20,000.

The cultivation, sale or manufacture of five grams or less of weed is considered a Class C felony, carrying a prison sentence of up to seven years and a fine of as much as $5,000. If someone is convicted of selling cannabis within 1,000 feet of a public housing building or within 2,000 feet of a school, they face anywhere from 10 years to life in prison and a fine of between $5,000 and $20,000. However, Senate Bill 56, introduced in Dec 2016, will allow licenses to be granted for the manufacturing, cultivation, distribution, and sale of medical marijuana.

Even the possession of paraphernalia could result in a year in jail and a fine of up to $1,000. will continue to monitor developments in Missouri medical marijuana laws and keep you updated. Hopefully, legislative efforts will one day make it possible for patients in the state to find the relief they need without having to turn to powerful, potentially addictive medications.
