K2, a dangerous synthetic cannabinoid product – also known as spice, synthetic marijuana, legal weed or fake weed – is wreaking havoc in Illinois and hospitalizing dozens.   In Illinois, synthetic cannabinoids have killed two and hospitalized fifty-six for extreme bleeding. This toll is expected to rise. Believing they are like "pot" or "marijuana" is the public's first mistake.
Warfarin, a drug that prevents blood from clotting, has long been used for those at high risk of clots, and thus at an increased risk of stroke and other ills. A recent study indicates that not only is warfarin effective for that purpose, its use might also protect against cancer.  
A new, genetically engineered drug that counteracts non-coumadin, anti-clotting agents has passed some safety and efficacy tests. If future research confirms the results of a recent study, it may well remove one of the major drawbacks to the use of these newer anti-clotting agents.
