Two presidential candidates have endorsed lifting the federal prohibition on marijuana and several states are considering following Colorado, Oregon, Washington, Alaska and D.C. in legalization.
The states, including California, Nevada and Arizona in the west, are likely to have legalization ballot proposals this fall. Research shows that legalization tends to follow and be enhanced by decriminalization of small amounts, legal medical marijuana and the tax revenue that sales can generate.
a slight majority (58%) of Americans now supports legalization, a super majority of 71 percent of people under 35 years old were in favor.
