In 1931 the Louisiana Supreme court declared the
 “marijuana plant is a plant possessing properties deleterious to health and dangerous to the public safety and morals”. The court concluded that whiskey and wine were less injurious than marijuana. State v Bonoa 172 LA. 955-963, (1931}

Marijuana is arbitrarily classified as a controlled substance. Marijuana does not meet all three criteria. Marijuana is safe to use without medical supervision. The Attorney General of the United States has the authority to add or remove any drug that does not meet all three critria. But congress has made it so the AG can not do this because of an obligation to a United Nations Convention.

The “placement in schedule I does not appear to flow inevitably from the lack of a currently accepted medical use.” “The legislative history of the CSA indicates that medical use is but one factor to be considered and by no means the most important one.” NORML v. D.E.A. 559 F2d 735 at 748 (1977)

Safety of use is the most important criteria that determines medicinal use. Marijuana is safe to use without medical supervision.

Part 4 VIII. ACCEPTED SAFETY FOR USE UNDER MEDICAL SUPERVISION

p. 56-58 With respect to whether or not there is "a lack of accepted safety for use of [marijuana] under medical supervision", the record shows the following facts to be uncontroverted.

Findings of Fact

3. The most obvious concern when dealing with drug safety is the possibility of lethal effects. Can the drug cause death?

4. Nearly all medicines have toxic, potentially lethal effects. But marijuana is not such a substance. There is no record in the extensive medical literature describing a proven, documented cannabis-induced fatality.

Press Release
On April 20, 2006 The U.S. Food and Drug Administration that smoked marijuana is harmful.
http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/2006/ucm108643.htm

Inter-Agency Advisory Regarding Claims That Smoked Marijuana Is a Medicine Marijuana is listed in schedule I of the Controlled Substances Act (CSA), the most restrictive schedule.

The Drug Enforcement Administration (DEA), which administers the CSA, continues to support that placement and FDA concurred because marijuana met the three criteria for placement in Schedule I under 21 U.S.C. 812(b)(1) (e.g., marijuana has a high potential for abuse, has no currently accepted medical use in treatment in the United States, and has a lack of accepted safety for use under medical supervision). Furthermore, there is currently sound evidence that smoked marijuana is harmful. "
