There is a presumption that a qualifying patient or designated caregiver is engaged in the medical use of cannabis in accordance with this chapter if the cardholder is in possession of a registry identification card and an amount of cannabis that does not exceed the allowable amount of cannabis. The presumption may be rebutted by evidence that conduct related to cannabis was not for the purpose of treating or alleviating a qualifying patient's debilitating medical condition or symptom associated with the qualifying patient's debilitating medical condition under this chapter.
