Public Opinion: In Gallup Poll, Support for Legalizing Reaches All-Time High; Over 50% in the West Are in Favor According to the most recent Gallup poll, 44% of Americans favor legalizing marijuana, while 54% oppose it. The 44% figure is the highest since Gallup began polling on the issue nearly 40 years ago. In 1970, only 12% of respondents favored legalization. That figure climbed to 28% in 1977, then declined slightly and reached a plateau with support holding at around 25% for the next two decades. But in the past decade, public opinion has begun to shift, with support hitting 34% in 2002, 36% in 2006, and now, 44%. Conversely, opposition to legalization is now at an all-time low. It was 84% in 1970, 66% in 1977, and around 73% for most of the Reagan, Bush I, and Clinton eras. But beginning in about 1996, opposition began to decline, dropping to 62% in 2002, 60% in 2006, and now, 54%. A related question—whether marijuana should be legalized and taxed to raise revenues for state governments—won similar support levels in the Gallup poll. Some 42% of respondents said they would favor such a move in their state, while 56% were opposed. In the West, however, support for tax and legalize has gone over the top; 53% favor such an approach. Looking at various demographic groups, support for marijuana legalization is highest among self-described liberals, at 78%. Only 26% of conservatives and 46% of moderates supported legalization. Similarly, 54% of Democrats, 49% of independents, and 28% of Republicans supported legalization. There is also a clear generational divide. Half of those under age 50 support legalization, compared to 45% aged 50 to 64, and only 28% of seniors. Support for legalization has swollen among certain demographic groups since the last Gallup poll on the issue in 2005. The number in favor of legalization jumped more than 10 points among women (+12), young people (+11), Democrats (+13), liberals (+15), moderates (+11), and residents of the West (+13). If these rates of increase in support for legalization continue over the medium term, the world as we know may indeed end in 2012.
