Actor Hudson Meek‘s death is being treated as an accident, and it doesn’t appear substances played any role in the fall that took his life … TMZ has learned.

Law enforcement sources tell us … no foul play is suspected in Hudson’s death — and, cops are looking into this as an accident.

We’re told there were no signs of drugs or alcohol … and, cops do not believe they played any part in the accident.

As we told you … Meek suffered blunt-force trauma injuries from a fall on December 19 in Vestavia Hills, Alabama.

Hudson was rushed to an area hospital … but, sadly, he passed away two days later.

His mother wrote a message about her son to Facebook shortly after his passing … mentioning all he accomplished and the people he impacted in the course of his short life. He will continue to make an impact too — with his organs being donated to those in need.

Among his credits … Meek appeared in “Baby Driver,” “MacGyver,” “Found,” “The School Duel,” “90 Minutes in Heaven,” “Badanamu Stories,” and many more projects.

Hudson was just 16 years old.

RIP
