Iowa limits medical cannabis purchases to 4.5 grams of THC per 90 days unless the patient has a waiver. On this two-page form, the practitioner who certified the patient's current registration card certifies, based on a current exam and history, the grams per 90-day period needed to alleviate the qualifying condition or its symptoms.
The same Iowa MD, DO, PA, ARNP or DPM who certified the current card completes page 2: practitioner information, the purchase limit in numbers and words, and signature. The patient's information goes on page 1.

No. Form 470-0192 must be completed by the same provider who certified the patient for their current registration card. That practitioner certifies, based on a current examination and the patient's history, the purchase limit in grams per 90-day period that should be approved.
4.5 grams of THC per 90 days. Patients certified for a terminal illness can have a higher amount set at certification; other patients need this waiver from their original certifying practitioner after participating in the program and being examined again.
