“Most people who live in a former meth house don’t even know it,” he says. “And some hotel rooms have also been contaminated.”
Recently, Morrison was awarded $116,000 from the National Institute of Standards and Technology to research the interactions between building materials and the chemicals used in methamphetamine labs.
Methamphetamine cooks use a potent combination of ingredients, including ammonia, methanol, ether, benzene and reactive metals. According to Morrison, the chemicals penetrate into materials like paint, wood and vinyl flooring and then “slowly come back to the surface over time.”
Morrison is concerned that children who make contact with the surfaces will ingest methamphetamine. Also, he says, lingering methamphetamine can be released into the air, where it bonds with tiny chemicals that are floating around. This means it could be inhaled, even months to years after rooms were thoroughly cleaned.
“We want to be comfortable with the cleaning methods,” Morrison says. “Are these methods sufficiently protective? How much should people be concerned about living in a former meth house?”
Morrison is leading the Missouri S&T study in conjunction with researchers at the University of Texas-Austin. In order to see how the chemicals interact with building materials, they plan to examine samples taken from homes after a bust and clean-up.
According to Morrison, standard decontamination procedures may need to be amended in the future to include additional steps that are more technical.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
