Three years ago, Alexis began taking medical marijuana, and her seizures disappeared. But that treatment option is threatened by an aggressive federal crackdown on medicinal cannabis led by Sessions, who is also the acting director of the Drug Enforcement Administration. Her day in court—February 14, at a New York City federal courthouse—is fast approaching. Alexis won't be there in person, but her lawyer, Michael Hiller, thinks the ruling will go their way. "We are very optimistic that the case is going to come out the way it should, which is that the Controlled Substances Act is going to be found unconstitutional," Hiller said. Several other plaintiffs—a former professional football player, a veteran and another child—are also included. The basic outline of Alexis’s story has been well reported: Horrible seizures forced her family to move to Colorado from Texas, where she could use products with compounds derived from marijuana. But due to the concentration of THC, also known as tetrahydrocannabinol, in one of the products she uses, Alexis is unable to cross state lines, board an airplane or set foot on a military base or in other federal buildings and lands.
