THC, or Delta-9-tetrahydrocannabinol, is the psychoactive found in cannabis plants. As the compound that produces the intoxicating effect, marijuana-derived THC and its products are illegal at the federal level.
However, each state has varying laws about THC products. Some allow the medical and recreational use of marijuana-derived THC products.
State laws across the 50 states are ever-changing. To help you keep up, this article provides updated information on THC’s legal status for each state.
| ❗Disclaimer The details below are accurate as of November 2023. While this page is regularly updated, some law specifics may have changed since the last update. |
Marijuana-derived Delta 9 is federally illegal in all US states. However, the 2018 Farm Bill (now known as the Agriculture Improvement Act of 2018) made some adjustments to THC’s legal status.
Since 2018, all cannabis plants containing 0.3% Delta 9 THC by dry weight volume are considered legal. Hence, products with THC that don’t go beyond the 0.3% content mark can be possessed, manufactured, sold, and used across all 50 states.
What if your state law on THC contradicts the federal law? The US Constitution says that federal law displaces or preempts state law.
What this means is if a state law directly comes in conflict with a federal law, the latter shall prevail. However, since America is styled under federalism, state and federal laws can overlap and exist in parallel. So far, the federal government hasn’t made any significant move to preempt state laws on Delta 9.
