The 41-year-old is supporting Texas based League of Young Voters Education Fund's No Guns Allowed movement, which was inspired by his song that he made after shooting rampages across the US.
"No Guns Allowed is a really important song to me. I'm humbled that an organisation like the League of Young Voters Education Fund supports what I'm saying in it and is taking action. Especially since they have been doing work for a long time to spread an anti-violence message in our communities," contactmusic.com quoted him as saying.
The campaign will involve anti-violence rallies and the launch of a petition supporting a proposal for background checks on anyone buying weapons.
The group's Executive Director Rob 'Biko' Baker said: "The League is excited and honoured by Snoop's support. We're looking forward to collaborating with him in the near future to reach even more people and bring some much-needed attention to the work we've been doing for some time to make urban communities safer."
