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.
Twenty-six states and the District of Columbia currently have laws broadly legalizing marijuana in some form. Three other states will soon join them after recently passing measures permitting use of medical marijuana. Seven states and the District of Columbia have adopted the most expansive laws legalizing marijuana for recreational use. Most recently, California, Massachusetts, Maine and Nevada all passed measures in November legalizing recreational marijuana.
