The action of the sessions essentially changes the federal policy from the non-intervention approach adopted under the Obama administration to freeing federal prosecutors to individually decide how to prioritize resources to crack down on the possession, distribution and cultivation of the drug in those states.  Paul told Michael Smerconish of CNN that Americans should have a choice over the use of marijuana, and called Sessions' actions "unconstitutional."
"It represents something that is so anti-American, as far as I'm concerned". the libertarian of Texas said.
"The war on drugs, for me, is a war against freedom, I think we concentrate too much on the drug issue itself, and I focus on the issue of freedom of choice, on doing things that They are of great importance, "he said. "And we allow high risk all the time … Generally, we allow people to eat what they want, and that is very risky, but we focus too much on what people put in their bodies."
Paul called the war on drugs a "totally illegal system."
"The fact that you legalize something does not mean that everyone does it, and then, if you look at the consequences of the war, why do not people look at it and read and study the ban? … (a) total failure, and the war on drugs is just as bad and worse, "he said.
"People should have the right or responsibility to deal with what is dangerous," Paul insisted. "Once you get into this about the government protecting us against ourselves, there is no protection of freedom."
However, he said, he did not expect the sessions to succeed.
"I predict that Sessions will not be victorious in this," Paul told Smerconish.
"And unfortunately, it's for reasons I'm not excited about, because the states want to collect all those taxes (on marijuana), so it becomes this fiscal problem," he said.
