If full legalization were to occur in all 50 states and D.C., the U.S. marijuana retail market could top $35 billion in revenue by 2020, according to estimates from independent research firm GreenWave Advisers.
In the US, 1 cup = 8 fluid ounces (*not identical to the avoirdupois ounce which is weight). In the US, one standard measuring cup contains 8 fluid ounces, but there is also a dry measure using the term cup, equal to 8 ounces.
Though almost everybody knows how much an ounce1 is, sometimes it is not easy to understand how many ounces there are in one cup. The problem is that not all known cups are equal in volume, because the definitions of the cup are different in various systems.
