I don't know about slamming dope, but, otherwise: Founding Clause, 9th, 10th, 18th, 21st. Why do you need a constitional amendment to allow cops to jail people for alcohol, but no other form of processed drug? It couldn't be clearer that we violate our Consitition when we arrest people for consuming psycho-active drugs. The feds totally caved on this question in passing the 18th & 21st Amendments.
