It's only another step downhill IMO.

- The government spends lots of money trying to fight marijuana.
- So we legalize marijuana and now use that same money to fight cocaine.
- Oh no, now we're spending a lot of money on fighting cocaine!
- Why not just legalize cocaine now?


See how that's a real half@ssed excuse? Sure, there are worse drugs out there, but if you legalize something like marijuana, then other drug users will start pressing for legalization of other drugs. They'll even use the same excuses that you're using now.

Give somebody an inch, and they'll try to take a mile.
