A campaign to legalize marijuana in Nevada begins Tuesday. The Committee to Regulate and Control Marijuana wants to make it legal for adults 21 and older to use marijuana in the privacy of their own homes.

They also want to set up a system where marijuana can be sold and taxed in smoke shops. Now the group will try to convince Nevadans it's a good idea.

Voters will decide on the group's initiative on the November 2006 ballot. Nevadans defeated a similar ballot measure in 2002.
