So those that are underage can purchase it from legal sources in your neck of the woods? I think not.
Who said that they could?

With drugs it would be the same and the legal ones would be at a higher price for users than the illegal.
Why? I don't mean to be a contrarian but I don't see what you're basing this on? If you're comparing the street price for marijuana to the prescription price of a pharmaceutical drug, i.e., valium, I can understand why you'd think that but valium is a highly processed drug. Marijuana is a plant. I don't see why it would be priced highly relative to alcohol or tobacco, if Amsterdam is any indication of how things would go if pot were legalized here. And that is just one example of a natural drug. Mushrooms and peyote are other examples. Maybe cocaine or heroin would cost a lot to cover the refinement process (as well as to price gouge addicts) but that's already the case now where they are illegal and thus not as readily available.

I see this with cigarettes now. Legalizing them would not stop the cartels from bringing them across the border, it might reduce the profits some but not enough to make it unprofitable.

Well, cigarettes vary in price largely by taxes imposed state to state

Blame bureaucracy and government waste, not tobacconists.
