Growing in Illinois

Growing marijuana in Illinois, if you aren’t a patient, could get you in trouble. Do not attempt to grow more than five plants at one time. First of all, you don’t need to. Secondly, growing more than five plants is guaranteed prison time if caught.  However, growing fewer than five plants is a civil violation. If you plan to grow in this state, stay small.

Growing a single plant is the best way to get started. You can read some tips on growing in the free ebook, The Marijuana Grow Bible. It covers various methods for safely growing weed in Illinois, as well as tips on getting the best yield from your plants.

Possessing Cannabis in Illinois

Possessing marijuana

Illinois legalized small amounts of marijuana for use by adults (both residents and visitors) in 2019. As long as you have less than 30 grams in your possession (15 grams if you are not a resident) you will not get in trouble. If you have more than 30 grams, however, you could face jail time.

Illinois has finally updated its laws to something more reasonable, and many people are now able to legally grow. Plus, those who aren’t patients, but are only interested in growing a few plants for personal use face minimal charges.

It’s not 100% legalization, but it is definitely a step in the right direction. Now with the right kind of seeds and knowledge, nearly any Illinois adult can discreetly grow their own marijuana.

  1. Please update your laws concerning Illinois, especially the growing which is legal for medical card holders, and penalties for others without medical card.

  2. Illinois became the 11th state to legalize marijuana for adults and Medical Cannabis patients can grow up to 5 plants starting Jan 2020.

    So, the information at ILGM “…. Illinois has a medical marijuana program, but unfortunately it does not include growing marijuana. Therefore, medical and casual marijuana users that are interested in growing weed in Illinois must do so without getting caught. There is a penalty of up to a year in jail for growing just a single plant, so being discreet is definitely worth the effort….” is not accurate and this should be updated.

  3. Someone needs to up date the Medical Cannabis Laws of Illinois, as of this coming Jan 1st 2020 medical cannabis patients with a Illinois card will be allowed to grow up to five plant for their medical use. This is Fact. This is attributed to the passing of the recreational Marijuana law that goes into effect Jan 1st 2020 !

  4. what? isn’t this instagateing “crime”? wow. I’m confused. the law says don’t grow but this clearly says ” go ahead just don’t get caught” … well basicly. i have glaucoma and it would be nice if I could have free medicine at hand. but the state needs money. meanwhile i slowly go blind if I don’t have the cash. i got my licence. oh yes for a pricey $400. not easy money to come by. but thank God it’s a step in the right direction. i just want to save the tax payers and myself some money. cause none is covered by state aid. it’s not easy being sick in illinois. nature has the cure for my ailment. and it’s free to grow. why not?!?!
