Talk about a shocking comeback attempt ... 

The man who owns the Nevada brothel where Lamar Odom overdosed last year says he wants L.O. back -- offering free women and booze ... but is adamant, absolutely NO DRUGS THIS TIME!! 

So, why would anyone think this is a good idea?  

We spoke with Love Ranch owner Dennis Hof who says sex and alcohol weren't Lamar's issues -- it was drugs. So as long as Lamar stays clean, why not go back to a place he enjoyed? 

Hof says he has a strict NO DRUGS policy at his place -- and thinks the companionship and some Remy Martin at the Love Ranch could be good for Lamar. 

"First night and 2 girls are on me," Hof said ... "plus all the Remy Martin you can drink." 

Hof says he will personally ensure L.O.'s privacy -- shutting down the security cams and collecting all phones. 

As for people who will be critical of his offer, Hof says -- "Don't forget, the people who work here are the one's who saved his life. We truly care about him."
