The popularity of the Doritos Locos Tacos has resulted in over 450 million being sold so far and Taco Bell being forced to hire thousands of additional employees to keep up with the demand. FastCompany detailed the relationship between Taco Bell and Frito-Lay, learning that the world hasn't seen anything yet. The Doritos Flamas Tacos are reportedly up next, and because there are over 100 Doritos flavors, new taco collaborations will continue to roll out in the future. 

Nobody's going to be mad at that; not the potheads and definitely not Taco Bell or Frito-Lay.
