The United States of America have been on the forefront to advance research on the benefits or harmful effects of marijuana. Scientists have proved beyond reasonable doubt that marijuana holds certain medical properties. Legislation for the medical use differs from one state to another. The possession, use, and transportation of marijuana are illegal under the US federal law, but various states have passed laws contrary to the federal law.
The state passed marijuana laws on November 2, 2014, through a ballot. The marijuana law in Alaska allows its residents to use marijuana for medical purposes and recreational use. The bill seeks to regulate the cultivation of marijuana at only 24 plants per individual for their own consumption. Residents in the state growing for commercial purposes must have a license. The maximum amount one can carry at a particular time is one ounce or 28 grams.
Decriminalization of marijuana happened on November 7, 2000 for adults over the age of 21. Any minor under 21 years of age will be charged with a misdemeanor. The laws were passed allowing for medical use only. The vote was 65% of Nevada residents in favor of the decriminalization of marijuana.
The residents of Michigan voted in support of Proposal 1 in November, 2008. On December 4, 2008, medical marijuana was legalized. Patients with conditions like HIV, cancer, and Hepatitis C are allowed to carry up to two and a half ounces of usable marijuana. The act also allows for the possession of 12 plants in an enclosed and locked facility for medicinal use only. Recreational use will attract a jail term of one year and a $2000 fine.
The National Center for Natural Products Research in Oxford in the state of Mississippi is the only facility licensed by the National Institute on Drug Abuse to grow marijuana purely for scientific research.
