What could POTssibly go wrong?-------Indian tribes free to grow pot on their lands – as long as they follow federal laws

Indian tribes free to grow pot on their lands – as long as they follow federal laws | US news | The Guardian:
"American Indian tribes can grow and sell marijuana on their lands as long as they follow the same federal conditions laid out for states that have legalized the drug, the US Justice Department has said.
Oregon US attorney Amanda Marshall said on Thursday the announcement addresses questions raised by tribes about how legalization of pot in states like Oregon, Washington and Colorado would apply to Indian lands.
Only three tribes have expressed interest in growing and selling marijuana, said Marshall, who co-chaired a group that developed the policy.
One is in California, one in Washington state and one in the midwest. She did not name them."
