Which strategies (or combination of strategies) do you think makes most sense to implement in response to drug crime?

With drug crime seeming to increase many different strategies, some that are already in place, are being enforced in order to serve justice and protect the community.   One strategy that I feel needs to be enforced a little bit more is surveillance and communication.  Since drug crimes leak into many different areas, through the selling and buying of the product, it is important that all areas of law enforcement are able to communicate with one another.  With a wide range of crime there is not just one jurisdiction so it is important that surveillance is kept up so that crime can be dealt with.  Also enforcing the laws to a fuller and harsher extent in order to keep drugs away from the youth and stop the massive spread of these toxic chemicals.
