Lamar Odom -- Surfaces Near Home, Looking Thin

Lamar Odom is wearing the stress of his marriage -- and possibly his NBA career -- falling apart as he battles addiction to hardcore drugs ... and TMZ has the first photos of him in several days.

Lamar's face looked gaunt when he was spotted Monday afternoon driving his SUV around the San Fernando Valley ... not far from his home with Khloe Kardashian.

As TMZ first reported ...Khloe kicked Odom out of the house last Wednesday when he rejected her attempt to stage an intervention -- hoping to convince him to get treatment for his addiction to crack cocaine.

But 2 interesting signs from Lamar's outing Monday -- he was still wearing his wedding ring ... and he was spotted driving into the gated community where he and Khloe live.
