Here's an article from Forbes magazine talking about which states will be next to legalize marijuana. There are currently 6 states with initiatives. According to the article, chances are good that it will be legalized in California (surprised it's taken this long), Nevada, and Maine. Less but still some chance for Ohio, Arizona, and Mass.
Also, a recent
Quinnipiac University poll shows that three swing states in the upcoming presidential election favor legalizing medical marijuana by huge margins, and legalizing in general has smaller but still majority support. That might change the debate a bit in favor of tolerance. Or even allow a real discussion, which would be a new thing.
Combined with the recent Compassionate Access, Research Expansion, and Respect States (CARERS) Act introduced in the Senate and the House to limit federal interference with states that have legalized medical marijuana, I am the most hopeful I've ever been that prohibition will be ended in my lifetime. Retirement keeps getting better and better!
