Michael Lohan is insisting that Lindsay Lohan was high on prescription pills the night she hosted SNL earlier this year, On SNL, Lindsay was not using any illicit drugs or drinking, but is still on the prescription drugs that they gave her. And the meds that they give her are meds that they say she needs, but she doesn't need them. But they kind of make her flat. She's not acting at a full potential. Its like the screen is down over her.
