Is Delta 9 THC Legal in Illinois?

The majority of people are aware that the 2018 Farm Bill made hemp farming legal on a federal level. This raises the question: Is Delta 9 THC legal in Illinois as well?

To sum it up quickly, yes! As of the time of writing, CBD, Delta 8, and Delta 9 as well as all other cannabinoids and hemp-derived goods are legal under federal law.

In truth, Illinois has allowed the recreational use of marijuana since June 2020. This implies that buying cannabis products, even those containing Delta 9 THC, is lawful.

Illinois House Bill 1438

Illinois legalized personal THC use in 2019, putting an end to cannabis prohibition and establishing a system to tax and regulate cannabis for anyone 21 and older. Following the Agricultural Act of 2018 ("2018 Farm Bill"), which delisted hemp and its derivatives (Cannabis sativa-L containing no more than 0.3% THC) from the Controlled Substances Act and legalized the production and sale of specific hemp-derived THC and CBD products, Illinois decided to follow suit.

The Illinois General Assembly unanimously approved the Industrial Hemp Farming Act in the spring of 2018 and it was signed into law on August 25. The Act empowered the Illinois Department of Agriculture to grant farmers in Illinois permission to grow industrial hemp.

On June 25, 2019, Governor J.B. Pritzker signed HB 1438 into law, separating hemp from marijuana legally and legalizing the sale of specific hemp products. The newly passed legislation, which Senator Heather Steans supported, made it legal for adults to possess and use marijuana. It also enlarged the system for medical cannabis licensing, including forgiveness for marijuana-related offenses, and allowed qualified patients to grow marijuana at home.

In contrast to many other states, Illinois has three distinct authorities in charge of monitoring and regulating the cannabis sector. The following parties are jointly in charge of cannabis regulation and control:

The IDOA (Illinois Department of Agriculture), which administers laws and issues permits:

  • Cannabis cultivation facilities
  • Craft growers
  • Infusers
  • Transporters

The Illinois Department of Financial and Professional Regulation (IDFPR) is responsible for issuing licenses and regulates medical and adult-use marijuana dispensing businesses that sell marijuana to patients listed on the medical marijuana registry and to adults over the age of 21.

The Illinois Department of Public Health (IDPH) manages the medical marijuana program and patient registration.

With some limitations, marijuana usage for medical and recreational purposes is allowed in Illinois. As of January 1, 2020, adults 21 and older may possess cannabis and buy cannabis-related items in stores that have been authorized. Possession is limited to:

  • 30 grams of raw cannabis;
  • A product or goods infused with cannabis that has no more than 500 mg of THC.
  • Five grams of concentrated cannabis.

Medical Marijuana in Illinois

The Illinois Medical Marijuana Pilot Program was established in 2013, sales started in 2015, and Governor Bruce Rauner increased the program's availability in 2018. Before SB 2023 was passed, the Illinois Medical Marijuana Program, which is regarded as one of the most stringent medical programs in the US, was about to expire in July 2020.

The list of qualifying ailments for medical marijuana in the state of Illinois has grown since SB 2023 was passed in July 2019. Additionally, the state's medical cannabis program was made permanent by SB 2023.

For patients who meet the requirements, the state of Illinois issues a medical card, which can be obtained by registering with the state. In Illinois, holders of medical marijuana certificates pay significantly less in taxes when buying cannabis to treat certain medical ailments.

Conclusion

Delta 9 products are permissible in Illinois. You can easily get D9 products from any retailer or you can order online.
