How long does THC vape stay in your system?
When you vape THC, your body breaks it down at different rates depending on how often you use it and what kind of drug test you take. If you only use THC occasionally, a urine test usually picks it up for about one to three days. But if you use it a lot, it can stick around in your system for over a month sometimes more than 30 days. Blood tests don’t catch it for very long, usually just a day or two. Saliva tests fall somewhere in the middle, spotting THC for about one to three days. Hair tests are a whole different story they can show traces of THC for up to 90 days.
