The correct answer reflects that up to 20% of a THC dosage can potentially be stored in the body from consumption five days prior. THC, the primary psychoactive component of cannabis, is known to be lipophilic, meaning it is stored in fat cells and released slowly over time. This characteristic leads to the accumulation of THC in the body, particularly with repeated use, and makes it detectable in various drug tests even long after the initial use.

Understanding the metabolism and storage of THC is crucial for addiction counselors as it informs them about withdrawal symptoms, relapse risks, and the physiological effects experienced by clients over time. The pharmacokinetics of THC are complex, and the potential storage percentage reflects the compound's long half-life, especially in chronic users. This knowledge aids counselors in providing appropriate support and guidance for those undergoing treatment for substance use disorders.
