How Does Meth Get Metabolized?

Methamphetamine, which is water-soluble, easily traverses cell membranes. This allows it to swiftly pass through the blood-brain barrier and enter the brain.

The body processes and eliminates methamphetamine through the kidneys and the liver.

The kidneys take these metabolites out of the blood and then expel them through urine.
