Recent polls suggest the proposals are likely to pass in both Nevada and Colorado.
In the past four years, similar medical-marijuana measures have become law in California, Oregon, Washington, Alaska, Maine and Hawaii. Nevada's Question 9 would let doctors prescribe marijuana for severe illness and pain. And the state's policy-making drug commission, which fought the measure two years ago, has been silent this year. Nevada voters get it. Colorado's Amendment 20 would permit marijuana use for those with serious or chronic illnesses, under a doctor's care.
