Does Amazon want to sell cannabis and ship it someday?  Absolutely, they are already dabbling with prescription drug refills to a larger and larger test area now, but that is not the main goal with supporting marijuana legalization now, it is to expand their pool of eligible workers at $15 to $17 an hour.  The FBI and CIA have all faced similar problems and discussed it, especially around recruiting computer programs and “hackers”, since a large majority of that community would be unable to pass a marijuana drug test.
