how long benzos stay in your system
Benzos can stay in your system for up to 40 days for urinalysis If you are talking about just taking 20mg one time only and not taking it at all for at least 3-4 weeks before that or only taking that amount once every several days, then it will stay in your system no longer than, on average, 3-4 days.0mg of a benzodiazepine isn't being descriptive enough. Different benzos have different half-lives, and not all benzos are prescribed in the same dosages (i.e. 20mg of Xanax would likely leave you unconscious, while many people can take 20mg of Valium and function rather normally).
