SNOOP DOGG - I'M NOT NOT SMOKIN 'BLUE IVY, BUT I'M ADDICTED TO...

Snoop Dogg says he has yet to test out the new marijuana strain named after Jay-Z's little girl Blue Ivy ... because he's been a bit too preoccupied with something called, "Snoop Dogg master kush" instead.

Big Snoop and his posse were cruising around Hollywood last night when he filled us in on his latest "addiction" ... AND a new smoking product he's pushing these days.

Bonus Moment! -- Snoop's pal zings our photog with a pretty solid one liner at the end of the clip. Snoop's entire crew enjoyed a laugh at our guy's expense ... so, you probably should too.
