Suspected Aurora massacre shooter James Holmes took Vicodin before the attack and was also a marijuana smoker, according to reports posted over the weekend.

The 24-year-old from San Diego who was in L.A. as a summer camp counselor in 2008 took 100 mg of Vicodin about 2-and-a-half hours before Friday morning's attack at a screening of The Dark Knight Rises, reported the ABC news affiliate in Denver.

A report of his alleged weed smoking was attributed to the New York Post, but …

… we couldn't find the story nowhere online. TMZ points to a piece that doesn't mention such toking, saying:

… A man who lived across the street from Holmes told the NY Post he used to “see him smoking weed behind the apartment.” He told the paper, “Nobody ever really talked to him. He was alone a lot.”

If true it could be bad news for medical cannabis advocates. Marijuana has a powerful, psychoactive component that, like legal, prescription drugs, has the potential to be abused.

Last year we reported that Tucson massacre suspect Jared Loughner was known to smoke pot and Salvia.
