Don't you think there would be no "amount that remains when use or need is satisfied" when people in Jamaica smoke marijuana non stop? You can't have a surplus when the need is never satisfied.
__________________ Bobo Adobo is funnier and smarter than all of you, proven by the fact that he is currently in a high-paying and important government job where he earns a fat cash paycheck and much pussy. How did he get so famous and successful you ask? It's simple: he has never, in his entire life, watched one second of anime.
