I don't agree that domestic businesses would not be able to compete in a global pot market.

The first reason is import taxes. Surely the government would tax imported pot, just as they do other imported goods. This would raise the cost of imported pot, thereby giving the domestic businesses a small advantage over them.

Secondly, if a domestic business could lower costs by growing outside of the US, then they would (just like auto manufacturers). I don't think it would take very long for Phillip Morris to buy up the South American growers, along with their equipment, work force, and land.
