Illinois Marijuana Laws

With cannabis laws constantly evolving around the country, you may be wondering – is marijuana legal in Illinois? And if so, how much weed can I buy in Illinois? The answer to the first question is; yes. Medical marijuana has been legal since 2013 and recreational marijuana has been legal since 2019. In this article, we’ll take a look at how much weed you can have in Illinois as well as many of the marijuana laws in Illinois that all residents should be aware of.

So, is marijuana legal in Illinois? Let’s find out.

  • Is Marijuana Legal in Illinois?  

    Is weed legal in Illinois? Luckily for casual cannabis users, the answer is yes. Marijuana was officially legalized for recreational use in 2019 and recreational sales started in January 2020, while medical marijuana has been legal since 2013 and was expanded in 2019.

    Although recreational marijuana is now legal, medical cardholders can purchase marijuana at lower price points and receive priority in the event of a marijuana shortage.

    Many people wonder – is marijuana decriminalized in Illinois? The short answer is yes – the state was in the process of decriminalizing marijuana even before it was legalized recreationally.

    However, there are still some instances where you can face legal consequences for marijuana possession. This can happen if you are carrying more than the legal possession limit, are carrying marijuana underage, or are using marijuana in a place where it isn’t allowed.

    You can also face legal consequences if you grow marijuana without a medical card or attempt to sell it privately.

  • How Much Cannabis Can You Possess?

    How much weed can you have in Chicago? Anyone over the age of 21 can purchase recreational marijuana products, but Illinois marijuana possession laws still limit exactly how much you can have at one time.

    Right now, recreational users can have up to 30 grams of marijuana flower at one time. They can also have up to 5 grams of marijuana oils or concentrate and up to 500 grams of THC in an infused product, such as edibles.

    If you have a medical card, you can purchase much larger quantities of marijuana. Medical cardholders are allowed to buy up to 71 grams of cannabis in a two-week period. If you have a specific medical condition that requires a larger quantity, Illinois does grant waivers for some patients.

  • Age Limit for Possession

    You must be 21 or older to use cannabis recreationally in Illinois. However, the age limits are slightly different for medical patients.

    You can apply for a medical marijuana card on your own if you are 18 or older, but if you are under 18, your parent or guardian can apply for a medical marijuana card for you. In this case, your caregiver would be the one visiting the dispensary for you.

  • Can You Grow Your Own Weed in Illinois? 

    You can currently only grow your own marijuana in Illinois if you are a medical marijuana cardholder over the age of 21.

    You cannot sell or share the plants you grow in your home – they are only available for personal use. It’s also important to note that if you rent your home, you will need permission from your landlord in order to legally grow marijuana plants.

  • How Many Marijuana Plants Can You Grow in Illinois? 

    According to Illinois marijuana laws, medical marijuana cardholders can grow up to five plants in their apartment. These plants can be at least five inches tall and must be stored in a secure location that isn’t visible to the public.

  • Marijuana and Housing Laws

    Your housing situation is going to affect whether you can grow marijuana at home or not. Illinois marijuana laws say that if you own your property, you will be able to grow your own weed as long as you have a locked space to do so that it is out of public view.

    However, if you rent your home, your situation is going to be a bit different.

    Those who rent their home must get their landlord’s permission in order to grow marijuana legally. This can be tricky, especially in small apartment buildings where it would be difficult to keep the plants secure. It’s also important to note that those living in federally subsidized housing cannot grow their own marijuana under any circumstances.

  • Where To Buy Marijuana in Illinois

    Wondering where to buy recreational weed in Illinois? Don’t worry – there are plenty of dispensaries located throughout the state. These dispensaries are privately run but are licensed by the state.

    In Chicago alone, there are 10 dispensaries to choose from, many of which are accessible by public transportation. There are also dispensaries located in major cities and towns throughout the state, including Rockford, Peoria, Springfield, and Champaign, just to name a few. While most of these dispensaries are licensed for recreational sales, some only offer medical sales, so be sure to check before you visit the dispensary.

  • Age Limit for Buying Marijuana

    How old do you have to be to buy weed in Illinois? You must be at least 21 to purchase marijuana recreationally and at least 18 to purchase marijuana with a medical card. Illinois marijuana dispensaries have very strict security procedures and will check your identification closely when you enter.

  • Who is Allowed to Sell Marijuana in Illinois? 

    The only entities that can sell marijuana in Illinois are state-licensed dispensaries. State-licensed growers and dispensaries must adhere to very specific rules and regulations. This ensures that the marijuana you purchase from them is high-quality and safe to use.

    If you are caught selling marijuana privately, you will face legal consequences.

  • Where Can You Consume Marijuana Legally? 

    While marijuana is legal for recreational use, you cannot consume it just everywhere. You can legally consume marijuana in your own home as long as minors under the age of 21 are not present.

    If you rent, check to make sure that your landlord allows smoking or vaping before engaging in either of these activities.

    Legally, you cannot consume marijuana in most bars or public spaces. However, local governments in Illinois do have the option to allow marijuana consumption in certain businesses if they choose.

    As a result, you may find some smoke shops that allow you to consume marijuana in public, but always be sure to check their licensing first.

  • Can You Consume Marijuana While Driving?

    It is illegal to use marijuana while driving or to drive while under the influence. If you are caught driving under the influence, you could face a license suspension as well as fines up to $2,500. The legal punishment will depend on the severity of the offense and whether you’ve received a DUI before.

  • Cannabis Fines and Penalties in IL

    If you do not adhere to the current Illinois possession and distribution laws, you could face legal consequences. The exact punishment for breaking these laws will vary depending on the severity of the offense. In some cases, it could just be a small fine, but in more severe cases, it could result in jail time.

    If you possess between 30 and 100 grams of marijuana, you could be charged with a Class A misdemeanor, which can result in fines, probation, and jail time. The exact punishment will depend on the amount of marijuana and whether or not it was a first-time offense.

    If you are caught driving under the influence of marijuana, you could face similar punishments as well as a suspension of your license.

    Now that both recreational and medical marijuana is legal in Illinois, it’s easier than ever to consume it safely. It’s important to know the laws so that you can avoid fines and penalties.
