According to a CBS News poll conducted at the end of October, a slim majority of 51 percent continues to think that weed use should be illegal. But support for specifically allowing doctors to prescribe marijuana for serious medical conditions - or legalized "medical" marijuana - is far stronger: 77 percent Americans think it should be allowed. Still, even though most Americans support this, just three in 10 believe that the marijuana currently being bought in this country under state-authorized medical marijuana programs is being used in the way it has been authorized: for alleviating suffering from serious medical conditions. I say the hell with those three people.heh. 40 percent of Americans think the use of marijuana should be legal, while 51 percent think it should not. The percentage that favors legalizing marijuana is larger than it was back in 1979. I dont think i need to express what side of the poll im on.
