What is the validity period of a written certification for medical marijuana?

The correct answer is 1 year, as this is the established validity period for a written certification for medical marijuana in Hawaii. This means that once a healthcare provider issues a certification for a patient to use medical marijuana, that certification remains valid for 12 months from the date it is signed. After this period, the patient must obtain a new certification in order to continue using medical marijuana legally.

This validity period is important as it ensures that patients are regularly evaluated by their healthcare provider to assess their ongoing need for medical marijuana. It also helps to prevent the misuse of outdated or potentially inappropriate certifications.

The other options suggest longer periods, which do not align with Hawaii's regulations regarding medical marijuana certifications. A shorter validity period, such as 6 months, would not provide sufficient time for continuous patient care cycles. On the other hand, options indicating 2 years or 5 years could lead to patients using certifications that may not reflect their current health needs or legal requirements.
