Ok, I'm honestly interested in your thoughts here.
IMHO the civil war screwed up what this country could have been had we been able to keep federal power more curbed than it's become. I think the feds are way overstepping their bounds but from a practical standpoint there isn't much we can do.
To circle this back to drug laws I think that many states would have legalized pot already if it wasn't for federal pressure. That federal pressure should be illegal IMHO. The governor of WA state recently vetoed a medical marijuana law because of a direct threat from the feds.

I'd recommend Akhil Amar's book
The Bill of Rights that I mentioned earlier if you want to read more about this. One of Amar's major themes-- probably
the major theme-- is the degree to which the popular perception of state and federal authority changed between the ratification of the Bill of Rights in 1791 and the Fourteenth Amendment in 1866. In 1791, tyranny was central and liberty was local. The British monarchy subjected the colonists to all of the indignities recounted in the Declaration of Independence and the Bill of Rights, and their primary defense against the encroaching monarchy were local institutions like grand and petit juries and colonial legislatures. That's why, Amar argues, the original Bill of Rights was more concerned with republican structure and majoritarian rights than is commonly appreciated today. By 1866, that had all changed-- local state governments, especially but not exclusively in the South, were the enemies of liberty and the federal government was seen as a source of protection against state oppression. Thus the Fourteenth Amendment, which incorporated the Bill of Rights against the states, put the individualist, libertarian gloss on the Bill of Rights with which we're more familiar today. Obviously what was going on in constitutional law was also going on at other levels of government: the replacement of state power with federal power as the principal guarantor of liberty. Then of course, though Amar doesn't get to it, we'd have to think about the New Deal and the reasons underlying the Roosevelt Court's expansion of federal commerce power, which again was undertaken in large part due to the perception that localized state regulation was insufficient to meet the challenges posed by the Depression and the emergence of America as a world superpower.
I don't know if I'd say that this shift in the balance between state and federal authority "screwed up" the system or not. On one hand, it's certainly the case that the federal government has increasingly expanded its regulatory scope into areas traditionally committed to the state police power. I totally agree with you that federal interference with state medical marijuana laws is outrageous. On the other hand, the shift toward federal power hasn't been a uniformly bad thing for individual liberties. The federal government
was the primary guarantor of blacks' rights during Reconstruction, and however badly it may have done at that job, it would have been far worse to leave the former slaves to the mercies of unfettered state authority. It was also the federal courts that defended free speech and free exercise rights-- to the extent they were defended-- during the World War I-II and Red Scare eras (but see:
Korematsu), and the federal government-- the Warren Court with cooperation from the Eisenhower and Kennedy administrations, and eventually Congress in the Civil Rights Act of 1964-- that led the way to desegregation of public facilities and the elimination of
de jure racial discrimination.
So we're certainly living in a different world than the framers of the original Constitution envisioned, but different isn't necessarily worse. The federal government is by nature less directly responsive to individual and local concerns, so to the degree that power has shifted in its direction one might argue that the current setup is less truly republican than intended. Whether that is on balance a good thing or a bad thing, I'm not sure.
