Put that in your pipe and smoke it. Over the past year, support for legalizing marijuana has jumped 10 percentage points, and now a clear majority, 58 percent, of Americans say yes to making pot legal for recreational use. When the question was first asked in 1969, only 12 percent favored such a change. Also significant – 38 percent of Americans now say they have tried the drug at least once, which may have affected the change in approval.
