Surface waves. Seismic surface waves travel along the Earth's surface. They can be classified as a form of mechanical surface waves. They are called surface waves, as they diminish as they get further from the surface. They travel more slowly than seismic body waves (P and S).
Percocet can be detected in the urine for 3-4 days. A blood test can identify Percocet for up to 24 hours. A saliva test can detect Percocet for up to 1-4 days. Percocet, like like many other drugs, can be detected with a hair follicle drug test for up to 90 days.
Hydrocodone & drug testing. Different drugs have different detection times in your system, depending on how these substances will wear off. Hydrocodone is detectable in urine for approximately 2 and up to 4 days after last use, while it can be detected during a hair follicle test even after 3 months. Detection also depends on the sensitivity of the specific drug test.
