When did spice become illegal?

Spice, a synthetic cannabinoid, began to gain attention in the late 2000s, leading to various legal actions. In the United States, the Drug Enforcement Administration (DEA) placed many synthetic cannabinoids on Schedule I of the Controlled Substances Act in 2011, effectively making them illegal. Other countries also moved to ban these substances around the same time due to safety concerns and health risks associated with their use.
