Marijuana legality?

Yes. Legalise, regulate, tax. I'd do the same for most other drugs, and prostitution.

All drugs should be completely legal. Regulation does more harm than good, and taxation is theft. So I can't get behind those things.

Prostitution should be completely legal as well. 

There are no victims with any of these things, therefore they are not crimes by any reasonable definition.
