(1) Advising a qualifying patient about the risks and benefits of medical use of marijuana or that the qualifying patient may benefit from the medical use of marijuana where such use is within a professional standard of care or in the individual physician's medical judgment; or
(2) Providing a qualifying patient with valid documentation, based upon the physician's assessment of the qualifying patient's medical history and current medical condition, that the medical use of marijuana may benefit a particular qualifying patient.
In order to be in compliance with this section, and benefit from the protections it offers, a health care professional's recommendation must be based not only on the patient's qualifying condition (medical records) but also their current medical condition.
It becomes more and more difficult for the authorizing health care professional to claim that their recommendation is based on the patient's current condition, when there is large gap of time between the date the recommendation was made and when it became necessary for the patient to prove they are legal.
So while the recommendation without an expiration date may be valid, it is up to the recommending health care professional to attest to it's validity.
Especially with the new requirements that require the recommendation be on tamper resistant paper with at least a date of issue, it seems naive to rely on the police or prosecutor to not check with the issuing health care professional as to the validity of an open-ended recommendation.
If you believe your recommending health care professional will put their license and freedom on the line for someone they last saw in the distant past then take the Dept. of Health at face value and rest assured that your open-ended recommendation will keep you safe.
Personally I'll take the sure thing of at least yearly contact with my authorizing health care professional.
