DENVER (AP) -- Marijuana legalization debates in Colorado are picking up as the state considers legalizing the drug for recreational use.

Several debates have already occurred on the question, and more are planned. Debates are scheduled this week in Denver, Littleton and Fort Collins. Dozens attended a debate Wednesday at the University of Denver, where the presidential candidates will debate in less than a week. Former Republican Senate candidate Ken Buck argued against a drafter of the marijuana measure.

Marijuana proponents say the drug should be regulated like alcohol and taxed to raise money for school construction. Opponents say the pot measure would increase youth drug use and wouldn't raise that much money.

Colorado is one of three states considering marijuana legalization without a doctor's recommendation this fall.
