Recreational drugs of any kind shouldn't be legalized, because like gay marriage, it then opens up the way for liberals to take it even farther. They like to introduce perversion and aberrant behavior, piece by piece, and they've been allowed to get away with it.
That is an entirely different argument than the "people will steal it anyway"-argument you led with.
So: You are also in favor - for the same reasons - of again prohibiting alcohol?
