this is a great point.<p>I often think of the current research chemical market in regards to this: a poorly understood drug like MDPV makes the rounds on the internet, someone decides to take the risks for the rewards in the gray-area and makes it widely available, someone buys it at a gas station and ends up in the hospital after doing something dumb, a panic ends up getting it banned, and a short while later the cycle restarts with a new drug that is still in the gray-area of the law.
