We’ve had more states with larger populations have it legal. The fact is that for most of America’s history pot was legal, and for all but about 15 years it’s been at least partially legal in at least one state. The effects are there aren’t any.
Tell me the states where pot was legal within the last one hundred years.
Stupid, left leaning California, and Stupid left leaning Washington, have now been joined by increasingly stupid and left leaning Colorado. Do you know why Colorado has become increasingly stupid and left leaning? It's because those people who shat the bed in California have decided to come shat the bed in Colorado after moving there.
You aren't getting that Left wing nutjobs leave a trail of wreckage behind, and your "victory" in Colorado is just another manifestation of the wrecking ball.
