As marijuana legalization continues to expand across the United States, many users are left wondering how long the drug remains detectable in their bodies. According to a recent USA Today article, the duration can vary significantly depending on factors such as frequency of use and type of drug test employed.

Other tests, such as hair follicle analysis, can identify marijuana use for up to 90 days. Factors influencing detection time include body fat percentage, metabolism rate, and hydration levels.
