The mother of Amanda Bynes says that she has taken Amanda off the medications she was previously taking. As her conservator she is entitled to make all decisions about Amanda's medical needs, but it seems to me that the meds were what was helping Amanda resume a normal life with school and friends there and not hiring taxis to drive her across the country and setting off gasoline fires in the driveways of people. The meds and close supervision have also kept Amanda from being arrested.
Amanda's mother says all of Amanda's problems were because of pot and now that Amanda is off weed that she is fine and doesn't need her medications. This seems like a really slippery slope. Amanda was in a psychiatric unit of a very good hospital and they prescribed her the meds and according to TMZ Amanda was in such bad shape that she mimicked an exorcism and began biting herself. I have never known anyone who used pot to act like that.
Now, what this could also be is that Amanda was taking other drugs in addition to pot which could have been making her act this way. That seems like a stretch though. Amanda does have someone looking out for her best interest who acts as a check against her mom. That person would probably go to court and ask that Amanda begin taking medications again if it was necessary. The last thing Amanda needs right now is a return to the old Amanda lifestyle.
