Marijuana legalization votes this week in Colorado and Washington state don't just set up an epic state-federal showdown on drug law for residents. The measures also open the door for marijuana tourism.
Both measures make marijuana possession in small amounts OK for all adults over 21. The measures affect not just state residents but visitors, too. Tourists may not be able to pack their bowls along with their bags, but as long as out-of-state tourists purchase and use the drug while in Colorado or Washington, they wouldn't violate the marijuana measures.
That's assuming the recreational marijuana measures take effect at all. That was very much in doubt Friday as the states awaited word on possible marijuana lawsuits from the federal government.
