Should marijuana be legalized for recreational use by adults? That is the question that voters in three states are considering this November. Colorado, Washington and Oregon all have ballot measures that, if passed, would end marijuana prohibition in their state. Colorado's Amendment 64 which seeks the legalization of marijuana for adults age 21 and older appears to be popular among voters. A recent poll from Rasmussen showed that 61 percent of likely Colorado voters are in favor of legalizing marijuana if it is regulated the way that alcohol and cigarettes are currently regulated.
