Under the Controlled Substances Act, cannabis has been declared a Schedule I substance which is deemed to have high abuse potential and no medical utility.
However, it's common knowledge that cannabis has great medicinal benefit. This has been known for thousands of years throughout world history.
Various studies in the United States and around the world along with overwhelming empirical evidence have proven cannabis' medical utility as well as general harmlessness. The US Government indirectly admits to cannabis' medicinal potential through US Patent 6630507. In 1988, DEA Administrative Law Judge Francis Young recommended that cannabis be removed from Schedule I due to its harmlessness.
The US government and all agencies should have consistent policies, not maintain contradictions.
