Legalising Marijuana he United States

Posted on Updated on

For the first time in more than four decades of polling on the issue, a majority of Americans favor legalizing the use of marijuana. A national survey finds that 52% say that the use of marijuana should be made legal while 45% say it should not.

Support for legalizing marijuana has risen 11 points since 2010. The change is even more dramatic since the late 1960s. A 1969 Gallup survey found that just 12% favored legalizing marijuana use, while 84% were opposed.

Half (50%) of Boomers now favor legalizing marijuana, among the highest percentages ever. In 1978, 47% of Boomers favored legalizing marijuana, but support plummeted during the 1980s, reaching a low of 17% in 1990. Since 1994, however, the percentage of Boomers favoring marijuana legalization has doubled, from 24% to 50%.

Generation X, born between 1965 and 1980, came of age in the 1990s when there was widespread opposition to legalizing marijuana. Support for marijuana legalization among Gen X also has risen dramatically – from just 28% in 1994 to 42% a decade later and 54% currently.

Transparency International just released its annual Corruption Perceptions Index on the perceived level of public sector corruption in 176 countries around the world, and once again, Somalia, North Korea and Afghanistan rank as most corrupt, with scores of 8. (Burma, also known as Myanmar, joined them last year but has since moved up two spots, to just ahead of Sudan).
Here’s the map — darker red means more corrupt.

Somalia is the most corrupt, Denmark the least
The Corruption Perceptions Index scores countries on a scale from 0 (highly corrupt) to 100 (very clean). While no country has a perfect score, two-thirds of countries score below 50, indicating a serious corruption problem.
