30 questions of November: Question 1

Joe asked "How can I figure out whether my marijuana use is causing my depression or my depression is causing my marijuana use?"

this is a tough one. at first glance i thought this was rhetorical. similar to "if a tree falls in a forest ..." type question. marijuana and depression seem inextricably connected. but i think you can solve this one mathematically. you just need another variable.

x + marijuana = depression
or
x + depression = marijuana

x = ?
marijuana = 1 lb
depression = 0

Based on my calculations, x = a Giants loss. it's possible that x can equal other stuff too, but right now it's definitely the Giants.
