Colorado Governor John Hickenlooper is urging caution to states contemplating following Colorado's path toward legalized recreational marijuana.

It's difficult to figure out exactly how the Colorado governor feels about marijuana. Earlier this year, Hickenlooper said marijuana is "not as vexing as we thought it was going to be."

In October of last year, Hickenlooper said it was "reckless" for Colorado voters to legalize pot. Two months later he said he would have reversed pot legalization if he could, but then he said, "now, I'm not so sure". A month later, Governor Hickenlooper told 60 minutes legal recreational pot "can work".

Last month, in a conversation with Mic, Hickenlooper said when pot was legalized,  if he had a magic wand he would have reversed the vote. Now, he says "if I had that same magic wand, I'm not sure I'd wave it."

According to Hickenlooper, pot usage has remained flat, arrests are down (obviously) and the Colorado is on track to generate $100 million in tax revenue.

But, Hickenlooper cautions that the jury is still out on Colorado's marijuana experience. He's telling other governors we need more time, and recommends waiting another year or two to see how things go.

Actually, that's pretty good advice. There are so many things that come in to play when you're talking about legalizing pot beyond the surface benefits of tax revenues, and the surface pitfalls such as underage use and stone driving.
