Whoever we elect to be the next leader of the free world is going to have a lot of impact on our future. They’ll decide what wars we don’t fight, which ones we do fight, who has to how much in taxes, and either win or lose the world’s respect. Oh yeah, and they’re also going to have a big say in what happens to weed laws.

Marijuana has gained legal status in four states and D.C., and roughly half its states have medical marijuana programs. All that progress could either be continued or reversed by the next US President. And what happens if the leading Democratic candidate Hillary Clinton takes office?

The former Secretary of State recently sang the same tune on marijuana laws that she’s been singing since last fall – that the federal government should wait and see how legal cannabis affects the states in which its legal before making any country-wide decisions. In the meantime, Clinton has some plans to make medical marijuana research easier.

She told CBS Boston on Monday that, I think that states are the laboratories of democracy, and four states have already taken action to legalize, and it will be important that other states and the federal government take account of how that’s being done, what we learn from what they’re doing. And I do think on the federal level we need to move marijuana from the Schedule One of drugs, move it to Schedule Two, which will permit it to be the basis for medical research … A lot of experts in the field are telling me we’ve got to learn a lot more. For example, you’re taking marijuana for medical purposes, how does it interact with all the other drugs you’re taking? What should be the right dosage?”

Her party nominee rival Bernie Sanders takes a significantly harder stance on marijuana. The left-leaning senator told NBC News, “In my view, the time is long overdue for us to remove the federal prohibition on marijuana,” Sanders said to cheers. ”In my view, states should have the right to regulate marijuana the same way that state and local laws now govern the sale of alcohol and tobacco.”
