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.

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.

Most recently, California, Massachusetts, Maine and Nevada all passed measures in November legalizing recreational marijuana. Californiaâs Prop. 64 measure allows adults 21 and older to possess up to one ounce of marijuana and grow up to six plants in their homes.
