Amanda Bynes weird behaviour and ACCUTANE?

Tweet

So i was browsing perezhilton.com recently, every so often i get a craving for celebrity juice. I remembered hearing about amanda bynes here are some things: she is posting pictures of herself in wigs a lot on twitter, she only lights her apt with red lights, other weird behaviour, but she posted that she wants to weigh 100lbs at 5'8 and that she used accutane to clear her skin accutane is a drug reserved for the most severe acne cases! it damages your liver and if you get pregnant it can cause defects, so they warn you over and over about it very serious drug. what are your thoughts on this? is she out of touch? i think she is beautiful she certainly does not have acne bad enough to harm her body and why the wigs!? on perez it said that accutane is not legal in the states? it is in canada but what are your thoughts on the drug?
