Lamar Odom -- Focusing on Tacos ... Not Crack

Lamar Odom would rather order tacos than answer questions about his crack problem ... and we don't blame him ... his order sounds delicious.

The NBA star was making a munchies run moments ago, hitting up a Taco Bell drive-thru near his and Khloe's Tarzana home ... and proudly displaying his wedding ring ... when he was pelted with questions about his drug addiction.

Lamar wasn't feeling talkative, but he did manage to complete his order ... laughing in the process.

It's a good sign Odom has stopped smoking crack -- at least temporarily -- because one does not typically make food runs while zonked.

As we reported, Lamar has returned home after going MIA for several days and is now listening to his wife Khloe's advice, though he's still undecided about seeking treatment for his crack cocaine problem.

Fun fact: the famous Taco Bell chihuahua died in 2009. R.I.P.
