Maybe someone living in US can answer that.
I suspect that heavy crude, exported from Venezuela to the US after the US installs their preferred regime, refined in Texas heavy crude refineries, will drop the price of gasoline in the US. Also it is another chip in the reputation of the US, which may have knock on effects diplomatically with many nations. But those are harder to judge. As for the drug trade, I don't think that will change at all, I suspect that is 100% a cover story and legal mechanism to make the joint operation legal.
