Delonte West Left Medical Facility While Hallucinating

Delonte West was discombobulated on the streets of Houston last month because he was on the wrong medication and left his treatment facility while hallucinating ... but now he's on the road to recovery.

TMZ Sports spoke with people extremely close with Delonte who tell us everyone was scared and concerned for West after the photos surfaced last month.

Now, one of West's close friends tells us ... he wants people to know the 32-year-old is receiving treatment for his bipolar disorder thanks to quick action from friends, family, the NBA and his former agent.

"Delonte was at a facility where he received the wrong medication. He began hallucinating. Because of the hallucinations he walked out of the facility, barefoot, in the hospital gown. He went to go get food. That's when he was video taped and photographed."
