As of 2008, thirteen states have passed laws allowing the medicinal use of cannabis.
In most cases, the changes in state law were made through ballot initiatives – where voters can petition proposed law changes to be included on state and local ballots, allowing the public to vote for or against them.
Interestingly, where figures on such ballot initiatives are available, they show that laws in favour of medicinal hemp laws are approved by more voters and receive a greater percentage of the vote than any successful Presidential candidate in recent memory!

Cannabis was listed in the United States Pharmacopoeia from 1850 until 1942.
Under federal law, hemp remains illegal throughout the United States and is not approved for prescription as medicine.
The United States Supreme Court has ruled that the federal government has the right to regulate and criminalize marijuana, including in the 13 states listed above, even when the hemp in question is being used for medical purposes.
The United States federal government does not currently recognize any legitimate medical use, although there are currently seven patients across the entire USA who are permitted by Federal law to receive medicinal hemp for various illnesses (through the Compassionate Investigational New Drug program that was closed to new patients in 1991 by the George H. W. Bush administration).
In 1988, Francis L. Young, an administrative law judge with the United States Drug Enforcement Agency, declared that “in its natural form, [cannabis] is one of the safest therapeutically active substances known.”
