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.
Californians vote to legalize recreational use of marijuana in the state. Voters on Tuesday approved Proposition 64, making California the most populous state in the nation to legalize the recreational use of marijuana. The approval of the ballot measure creates the largest market for marijuana products in the U.S. It comes six years after California voters narrowly rejected a similar measure.
