Weed pens, which vape cannabis concentrates with high THC levels, can leave THC metabolites detectable in the system for varying lengths of time depending on several factors. Generally:
- For occasional users, THC metabolites may be detected in urine for about 3-5 days after use.
- For moderate users, detection can extend to 7-21 days.
- For frequent or chronic users, THC metabolites can be detected for up to 30 days or more, with some cases reporting detection for several months.
- THC is fat-soluble and stored in fat cells, so higher body fat can prolong detection time.
- Metabolism, frequency of use, amount consumed, age, and lifestyle (like exercise and hydration) all influence how long THC stays in the system.
Detection times can also vary depending on the type of drug test used (urine, saliva, blood, hair), with urine tests being the most common. THC from weed pens is detectable for a similar duration as other forms of cannabis consumption like dabbing or smoking. The psychoactive effects usually wear off in 1-3 hours, but THC itself remains detectable much longer in the body. In summary, THC from a weed pen typically stays in the system:
- About 3-5 days for occasional users,
- Up to 30 days for regular or heavy users,
- Possibly longer for chronic users depending on individual factors.
