An Obstacle to D.C.'s Medical Marijuana Law

'The April 19 editorial “Medical marijuana” made a wise observation regarding the D.C. medical marijuana law — “critical details will need to be worked out in its implementation” — but did not mention the key obstacle: the federal drug law and the Drug Enforcement Administration opposition. The D.C. law and those of 14 states are messy because they need to work around federal law. D.C. and the states would benefit from DEA cooperation, not opposition stubbornly grounded on the Constitution’s supremacy clause.'
