How does Vicente interpret the lack of an Amendment 64 response to date?

"It's an implicit support of these law changes," he allows.

Still, he goes on, "that doesn't mean people who get into this area -- people who possess marijuana, or business owners -- shouldn't be concerned about some degree of risk. But I think we're in better shape than we've been historically, because the federal government didn't come out with guns blazing about these laws."

Should entrepreneurs be concerned about future federal action? After all, the feds allowed a boom in medical marijuana dispensaries in 2009 through 2011 only to begin 2012 with shutdown-threat letters to dozens of dispensaries with 1,000 feet of schools.

"There's always some degree of risk," Vicente concedes. "But I think the risk is now less than it was six months ago, or six years ago.

"Business owners should be cautious," he goes on, "But at the same time, I think the winds are in our sails. Two states have legalized recreational marijuana" -- at least within limitations -- "and more and more states are passing medical marijuana laws. So at the end of the day, I think this will be a business opportunity."

He feels the same way about Amendment 64 in general. In his words, "this is an area with a lot of promise."

Especially since Eric Holder may be to busy to throw a spanner in the works.
