Either way is going to be very difficult, but I would say thw we have been concentrating more on the supply side and have little to show for it. So I think we ought to concentrate on the demand for a while.
Specifically, I think that we ought to have more programs to get people off drugs (and maybe more programs available to for at-risk kids so they are less likely to get into drugs). I think that if we severely reduced the demand for drugs, then the supply would be irrelevant. As it is, we try to stop the supply, but there's so much demand that the suppliers have a huge incentive to get their drugs in here somehow (submarine, for example!!).
