Johnny Lewis, an actor who appeared for two seasons on “Sons of Anarchy” and once dated Katy Perry, died Sept. 26 after falling or leaping off a roof. According to police, he may have killed his elderly landlady shortly before he died. While officials haven’t definitively said whether drugs were involved, some sources believe Lewis may have been high on a drug known as “Smiles,” which also have been linked to two recent deaths of teens. The drug, also known as 2C-1, is known for hallucinogenic effects and often is sold in powder or tablet form. The strength of the drug can vary widely, which contributes to its danger. In the space of two days, two teens—ages 17 and 18—died in East Grand Forks, N.D., in two separate incidents. (CBS News, Fox News)
