Urges the Illinois General Assembly to cap THC levels in marijuana by placing limits on the amount of THC contained in retail products, placing limits on the amount of cannabis a retailer can sell to an individual in a single transaction or over a period of time based on the amount of THC contained, and implementing a seed-to-sale tracking system, allowing regulatory agencies to view every gram of legal cannabis as it migrates through the supply chain, including monitoring ingredients added to cannabis that are eventually sold in retail stores.
