Illinois has a medical marijuana program that now includes growing marijuana. If you are interested in legally growing marijuana in Illinois, it is best to register first as a patient. If you are not a registered patient, there is a fine for growing up to 5 plants.

Growing in Illinois

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. No matter where you reside, the grow bible should be your first step to growing weed.

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.

Interesting fact; marijuana is not legal in Jamaica! Learn how Rastafarians get to appreciate ganja in our free ebook.

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.
