Johnny Lewis Struggled With Psychopathy: Adviser

Substance abuse may not have been Johnny Lewis' main problem, according to an alternative sentencing advisor who worked with Lewis for two months after his legal troubles started earlier this year. Lewis was struggling with "psychopathy or bipolar disorder," she tells E!. "Something that needed a psychiatrist rather than a therapist." She says she saw Lewis' troubles as mental, not related to drugs, and adds that he also had trouble taking his prescribed medication. The Sons of Anarchy star was found dead Wednesday after allegedly killing his landlady.

But there are also reports that Lewis was on a synthetic drug called 2C-I or "smiles" when he died, and CBS News has a look at the scary-sounding drug, which is similar to amphetamines and can cause hallucinations. An expert says they can be particularly dangerous because, like "bath salts," they can contain unknown chemicals. If he was in fact on drugs, one former president of the Scientology celebrity center tells Radar that Scientology could be to blame. Lewis could have "turned to drugs because of the pressure and intensity" of the controversial religion, she says. One thing is clear: There were warnings Lewis could get in serious trouble. People has a probation report from May, in which his probation officer warned that Lewis would be "a threat to any community" in which he lived. (More Johnny Lewis stories.)
