How long does vape stays in the system?

How long vape stays in your system depends on what you’re vaping (nicotine or THC), how often you vape, your metabolism, and which type of drug test is used. Here’s a breakdown:


🧪 If You’re Vaping THC (Weed)

Detection Windows for THC:

Test TypeOccasional Use (1-3x/week)Regular Use (4+ times/week)Heavy Use (Daily)
Urine Test3–7 days1–3 weeks3–6+ weeks
Blood Test1–2 daysUp to 7 daysUp to 10–14 days
Saliva Test1–3 daysUp to 1 weekUp to 1 week
Hair TestUp to 90 daysUp to 90 daysUp to 90+ days

⚠️ THC is fat-soluble, meaning it stores in your fat cells and can take longer to clear for heavy users.


🚬 If You’re Vaping Nicotine

Detection Windows for Nicotine:

Test TypeTime in System
Blood1–3 days

Saliva1–4 days
HairUp to 90 days

Cotinine, a byproduct of nicotine, is what most tests look for. It’s detectable longer than nicotine itself.
