Timeline of cannabis laws in the United States
Appearance
The legal history of cannabis in the United States began with state-level prohibition in the early 20th century, with the first major federal limitations occurring in 1937. Starting with Oregon in 1973, individual states began to liberalize cannabis laws through decriminalization. In 1996, California became the first state to legalize medical cannabis, sparking a trend that spread to a majority of states by 2016. In 2012, Washington and Colorado became the first states to legalize cannabis for recreational use.
Federal
[edit]- 1937: The Marihuana Tax Act is enacted, effectively prohibiting cannabis at the federal level. Although medical use is still permitted, new fees and regulatory requirements significantly curtail its use.[1]
- 1969: The Marihuana Tax Act is struck down in the case Leary v. United States. The Supreme Court rules that the act violates the Fifth Amendment's protection against self-incrimination.[2]
- 1970: The Controlled Substances Act is enacted. Cannabis is classified as a Schedule I drug, determined to have a high potential for abuse and no accepted medical use, thereby prohibiting its use for any purpose.[3]
- 1990: The Solomon–Lautenberg amendment is enacted.[4] As a result, many states pass "Smoke a joint, lose your license" laws under which any drug offense is punished with a mandatory six month driver's license suspension.[5][6]
- 2014: The Rohrabacher–Farr amendment passes the U.S. House and is signed into law. Requiring annual renewal, it prohibits the Justice Department from interfering with the implementation of state medical cannabis laws.[7][8] The Cole Memorandum had in 2013 assigned similar policies from within the Justice Department.[9][10]
- 2018: The 2018 farm bill legalizes low-THC (less than 0.3% THC) hemp and hemp-derived products such as cannabidiol (CBD) at the federal level. The bill also fully removed or "descheduled" low-THC cannabis products from the Controlled Substances Act, where they had been listed as Schedule I drugs since the CSA's inception in 1970.[3][11]
- 2022: The Medical Marijuana and Cannabidiol Research Expansion Act is signed into law to allow cannabis to be more easily researched for medical purposes. It is the first standalone cannabis reform bill enacted at the federal level.[12][13]
