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.
Currently, the use of both recreational and medicinal marijuana has been entirely legalized in the states of Alaska, Colorado, Oregon, and Washington. The cities of Portland and South Portland in Maine; as well as Keego Harbor, Michigan, have fully legalized marijuana for both medical and recreational use.
