How long does THC stay in the body

Dear Ask The Doctor: How long does marijuana stay in blood

Dear Octavio:

Tetrahydrocannabinol orTHC is a metabolite of Cannabis or Marijuana which is rapidly absorbed by the body either by inhalation or by swallowing saliva through your intestinal tract. It is almost completely metabolized, however low concentrations of THC may be detected in urine during the initial several hours, on the other hand tetrahydrocannabinol persists in urine at a detectable concentration for many days after smoking.

The period in which THC can be detected, depends on a number of factors such as weight of the patient, metabolism, concentration of Cannabis, age. Typically a person that smokes a single dose of marijuana have between 5 to 7 days of chance to be positive for THC, A chronic marijuana smoker could have positive results after 30 days of quitting. I hope I cleared your doubt.
