"I’m currently using Apothecanna extra strength topical cream 25mg THC, 25mg of CBD. "
Topical cannabis products begin working as soon as they are applied in most cases, and do not contain much THC, making them non-psychoactive. These products are highly unlikely to cause a failed drug test, as long as you don’t indulge in other, traceable ways such as smoking, edibles, or dabbing.
The exception to this are transdermal patches, which will allow THC to cross over into the bloodstream and cause a positive drug test, so avoid transdermals if you are concerned or need to get a job at a company that requires a negative test.
To be safe, it would be wise to reach out to the company who produces the topical you are considering using to ask them directly.
