Meth and the Brain. Meth releases a surge of dopamine, causing an intense rush of pleasure or prolonged sense of euphoria. Over time, meth destroys dopamine receptors, making it impossible to feel pleasure.
CAUSES OF HIGH AMMONIA. Ammonia is a normal by-product of processing nitrogen in the body, and is excreted as waste in the urine, in healthy people. However, elevated blood ammonia levels can occur when the kidneys or liver are not working properly, allowing this waste to remain in the bloodstream, which can be poisonous to your cells.
Testing for High Ammonia Levels in the Blood According to Medline Plus, the test to measure your blood ammonia levels can be done using a simple venipuncture blood test. To get an accurate result, you may be asked by your doctor to fast overnight before the test.
