Unless they're going to develop a pill for all possible cravings this is not a useful direction to go in. People need to develop their decision making skills, not pop pills for all problems.
The trend to keep highschoolers in line by drug testing randomly is also a bad policy. What are the kids going to do when Mother Highschool is no longer around? All these types of solutions try to do an end run around developing personal responsibility.
If you fund a carpenter to research drug addiction, he will tell you how to use a hammer upside the head. If you fund a medical researcher they will come up with a pill, and ask for more funding.

What we need to do is........everything. That means learning how the neural mechanisms work, try to develop drugs to block cravings, develop programs to deal with the psychology of addiction, etc. etc. etc. This addiction thing is a plague. And we need to understand the mechanisms...if you're advocating turning off the MRIs and PETs, unplugging the microscopes and spectrometers, then I couldn't disagree with you more. The more we know about the thing, the better we are able to combat it.
