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.
That makes California the largest state in the country to legalize recreational use of marijuana by adults 21 and older. While marijuana remains illegal under Federal law, California penalties for possession of less than one ounce of marijuana, for non-medicinal reasons, will no longer be enforced, Kleiser said.
