Definitions and Classification of Blood Pressure Levels. Essential, primary, or idiopathic hypertension is defined as high BP in which secondary causes such as renovascular disease, renal failure, pheochromocytoma, aldosteronism, or other causes of secondary hypertension or mendelian forms (monogenic) are not present. Essential hypertension accounts for 95% of all cases of hypertension.
In 1996, California voters passed Proposition 215, making the Golden State the first in the union to allow for the medical use of marijuana. Since then, 22 more states, the District of Columbia and Guam have enacted similar laws.
Voters in California, Massachusetts and Nevada decided yesterday (Nov. 8) to legalize the recreational use of marijuana in their states. These three states joined Alaska, Colorado, Oregon, Washington and the District of Columbia, which had already legalized the drug for recreational use in previous votes. In addition, four states voted yesterday to legalize using marijuana for medical reasons: Arkansas, Florida, Montana and North Dakota, Time magazine reported. That means that medical marijuana is now legal in 28 states, and an additional 16 states have laws that allow for limited medical use of the drug, according to Time.
