I don’t think she is a meth addict either. She appears to have a problem with prescription drugs.
Right, one of the prescriptions she is known to be on because of previous court filings, is Adderal - which is brand name for methamphetamine.
When people "cook" meth at home using over the counter cold medications, they are making methamphetamine. Chemically, they are virtually identical - or so closely mirror each other chemically, that they have the same psycho-stimulative effect.
