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.
Prior to the vote, it was legal to use recreational marijuana in only four states and in the District of Columbia. Colorado and Washington state voted to OK it in 2012. Alaska and Oregon voters approved it in 2014. For the states where recreational use is legal, it seems to have been a boost to the economy.
