Decriminalization passes in Massachussets
This initiative passed by a wide majority - approximately 2 to 1, making Massachussetts the first start to enact decriminalization via a ballot initiative.
Medical Marijuana legalized in Michigan
The bill legalizes the use of medical marijuana by patients with “debilitating medical conditions” when approved by a physician. Michigan will become the 13th state to legalize medical marijuana use
Here is the full text of Michigan's Proposition 08-01
Marijuana May Fight Bacteria
Research in the 1950's tested various marijuana preparations to see how they responded to skin and other infections so it has been known for decades that cannabis sativa possesses antibacterial properties. Most people are unaware of this research, however.
Back then, researchers had little understanding about the chemical makeup of marijuana. The current research has helped increase scientific understanding of this topic. Giovanni Appendino and colleagues, of the University of the Eastern Piedmont, looked at the antibacterial activity of the five most common cannabinoids. All were effective against several common multiresistant bacterial strains, although, perhaps understandably, the researchers suggested that the nonpsychotropic cannabinoids might prove more promising for eventual use.
The researchers say they do not know how the cannabinoids work or whether they would be effective, as systemic antibiotics would require much more research and trials. But the compounds may prove useful sooner as a topical agent against methicillin-resistant Staphylococcus aureus, or MRSA, to prevent the microbes from colonizing on the skin.
The study was led by Giovanni Appendino, of the University of the Eastern Piedmont, and published in The Journal of Natural Products.

Abstract:
Alzheimer's disease is the leading cause of dementia among the elderly, and with the ever-increasing size of this population, cases of Alzheimer's disease are expected to triple over the next 50 years. Consequently, the development of treatments that slow or halt the disease progression have become imperative to both improve the quality of life for patients and reduce the health care costs attributable to Alzheimer's disease. Here, we demonstrate that the active component of marijuana, 9-tetrahydrocannabinol (THC), competitively inhibits the enzyme acetylcholinesterase (AChE) as well as prevents AChE-induced amyloid -peptide (A) aggregation, the key pathological marker of Alzheimer's disease. Computational modeling of the THC-AChE interaction revealed that THC binds in the peripheral anionic site of AChE, the critical region involved in amyloidgenesis. Compared to currently approved drugs prescribed for the treatment of Alzheimer's disease, THC is a considerably superior inhibitor of A aggregation, and this study provides a previously unrecognized molecular mechanism through which cannabinoid molecules may directly impact the progression of this debilitating disease.
