My two cents quoted from another thread on this matter (no I have not spoken to an attorney):

Unless you’re ordering large quantities of a controlled substance (in which case you should be well aware of the risks involved anyway) I don’t think most OP customers have much to worry about other than having a harder time trying to obtain their meds.

It just wouldn’t be worth the DEA, etc.'s time, effort, and especially, money otherwise. As I have mentioned in previous posts, they are interested in the big guys. They feel if they can shut these places down, they will have accomplished their goal. If they nab some illicit drug dealers who were simply using these sites as a way to obtain their product in the process cool, but that is about as far as I think it will go.

Imagine the field day the media would have if they did try to bring a case against someone, well, like a 75 year old lady with no insurance ordering meds to control chronic pain. How precious government funds were being used to bring a federal case (which, since it involves interstate commerce it would have to be) against a little old lady trying to manage her pain.

I just can't see it happening.
