A couple dozen servicemen and women marched to the White House this Veterans Day and dumped a large box of empty pill containers, calling on the president and other federal officials to make medical marijuana accessible to veterans.

“Here’s what the over-medication of our veterans looks like,” they said as they spilled the canisters onto the floor. “We don’t want it.”
