Election could create flood of marijuana cash with no place to go

Although the sale of marijuana is a federal crime, the number of U.S. banks working with pot businesses, now sanctioned in many states, is growing, up 45 percent in the last year alone. Still, marijuana merchants say there are not nearly enough banks willing to take their cash. So many dispensaries resort to stashing cash in storage units, back offices and armored vans. Proponents believe the Nov. 8 election could tip the balance in favor of liberalizing federal marijuana laws, a move seen as key to getting risk-averse banks off the sidelines. Measures on ballots in California, Florida and seven other states would bring to 34 the number of states sanctioning pot for medical or recreational use, or both. That could push annual sales, by one estimate, to $23 billion.
