Lil Scrappy, Cash Out -- We're Happy For Colorado, But What About Us?

Lil Scrappy, Cash Out, and Warren G are THRILLED their Colorado peeps are free to smoke weed ... but still have one major concern -- what about ALL THE OTHER STATES???

The following is TMZ's in-depth analysis of Colorado's Amendment 64, aka ... here's what rappers think about the new ganja law:

Lil Scrappy: "It would be great if I was still blowing but I'm on chill mode for God. Liquor is legal and less harmful ... so [weed] should be legal everywhere too."

Cash Out: "It's great! I wish they would legalize weed everywhere and there would be way more happy people in this country."

Future: "Hey s**t, I don't live in Colorado but when I get there for a show we can smoke." He adds, "They need to bring [this law] to Atlanta."

Flesh-N-Bone: "Great for those guys, wish it would be good for us in Cali."

Bizzy Bone: "Weed legal is good anywhere."

Warren G: "I think this is the first step to all states making it legal."
