Controlled Substances - As introduced, permits a person to possess cannabis that was obtained directly from, or pursuant to a diagnosis of a qualifying medical condition by, a licensed physician; specifies the sentences permitted for possessing certain amounts of cannabis that was not obtained directly from, or pursuant to a diagnosis of a qualifying medical condition by, a licensed physician. - Amends TCA Title 39, Chapter 17, Part 4.

SB 2571 allows Tennessee residents with a qualifying medical condition to legally possess cannabis obtained directly from a licensed physician. It criminalizes unauthorized possession: possessing ≤1 ounce is a Class A misdemeanor with a $100 fine max or 10 hours community service (no jail), while larger amounts face escalating fines and potential jail time (up to 6 months for repeat offenses over 1 ounce). The bill specifically targets non-medical cannabis use, setting penalties based on quantity without jail for small amounts. It directly affects residents seeking medical cannabis access versus those using cannabis without a physician's authorization.
