This piece was originally written in 2003 & subtitled at that time: SEVEN YEARS CLINICAL EXPERIENCE

Clinical medicine, as I have experienced it during a quarter century of practice, is a constantly evolving system. Every practitioner has a different approach to gathering clinical information, diagnostic reasoning and therapeutic decision making.
 There is rarely a single correct way to care for patients. Instead, there is usually a wide variety of acceptable approaches, any of which may be appropriate in a given situation (Goldberg, 2002b).


Particularly for the student, but also for the experienced clinician working to incorporate a new technique or finding into his or her established practice, the array of choices may be disconcerting and may provoke a feeling of reluctance to enter into unfamiliar clinical territory. The use of medical cannabis to provide symptom relief to seriously ill patients is a practice that has been rediscovered and refined following the 1996 passage of the California Compassionate Use Act (“Proposition 215,”
which became Section 11362.5 of the state Health and Safety Code).

My practice



After the passage of Proposition 215, I began performing cannabis evaluations on a very limited number of my existing primary care patients, who requested it and whom I knew had clear indications such as nausea of cancer chemotherapy, 
Severe migraine headache, and 
Chronic pain.



Soon I was receiving referrals for medical cannabis evaluations for patients I had not seen before.  These referrals came from both patients and other health care providers. This is not surprising, since most doctors are reluctant to approve medical cannabis.  Most physicians don’t know the law, and  have never studied the medicinal uses and history of cannabis. Medical schools do not teach about cannabis’ potential benefits, medicinal uses and history. When this lack of information is added to concerns that many health care providers have about the legal and professional implications of cannabis recommendation, it is understandable that a minority of doctors are doing the majority evaluations on many cannabis patients.



As I began seeing more patients who were benefiting in a wide variety of ways, it became clear to me that I had to become better acquainted with the professional literature on cannabis as a medicine.

To the extent that my general primary care practice is typical, I would guess that most general primary care practices in the Bay Area  have seriously ill patients who would be likely to benefit from the use of medical cannabis. Possible benefits might include improved symptom relief, fewer side effects, and/or lower cost than many commonly prescribed pharmaceuticals.

 What is not typical about my practice is that even among the limited number of doctors who are performing medical cannabis evaluations, I am one of the few who does them in the context of a full-scope general medical practice.

Since that time, I have been conducting medico-legal consultations for 
patients who are weighing cannabis as a treatment option. I have worked to 
develop my own standards by reading the scientific literature, learning from
 the experience of other practitioners, and through application of my past
 experience in making clinical decisions.
 In describing my own approach, I in no way intend to define the standard 
that is appropriate for all providers or all clinical situations. Rather, this article represents the accumulated insights from my experience with medical cannabis as a treatment, with patients who have benefited from its
use, and with the practice of family medicine in a patient population that
includes persons from a wide variety of backgrounds, age groups and states
of health.
 My goals are to give patients some ideas about what might be expected from a
 medical cannabis consultation as it would be conducted in my office, and to 
give clinicians some information about which aspects of the patient’s 
history, diagnosis and physical condition I consider most relevant in
decision making about medical cannabis use.




Full Disclosure


I am one of approximately nine physicians who have been investigated by the
 Medical Board of California in relation to recommending medical cannabis.
 My strong belief that I was practicing the highest standards of medicine
 provided a level of comfort and confidence that I would not have expected to
 maintain during such a stressful, time-consuming ordeal. 
I was also reassured by having good legal counsel and the support of many
 fellow physicians, as well as my patients, family, and friends. In August,
 2003, one year after I was served a subpoena to appear at a Medical Board
 hearing, I was effectively exonerated.
  Regrettably, my experience with the Board has been shared by a number of
other responsible physicians who were also inappropriately targeted for
 investigation for having recommended medical cannabis.
 The complaints triggering these investigations have not come from patients 
or caregivers, but almost exclusively from officials in various branches of
 law enforcement.

“Acceptable Standards”


Because medicine is a constantly evolving field, there is a wide range of
 acceptable standards of care for treating many specific problems. This is
more noticeable in dealing with symptom management as opposed to
 curative therapy; it is particularly relevant in a new field such as 
Cannabis Therapeutics, in which research has historically  been constrained
 by legal considerations. 
In my practice, cannabis is most frequently employed for symptom management 
(Larson, 1992) as well as for the reduction of what has been termed “symptom 
distress” -the physical or mental anguish or suffering that results from the
 symptoms the patient is experiencing (Rhodes & Watson, 1987).

With appropriate use of medical cannabis, many of these patients have been able to reduce or eliminate the use of opiates and other pain pills, ritalin, tranquilizers, sleeping pills, anti-depressants and other psychiatric medicines, as well as to substitute the use of medical cannabis as a harm reduction measure for specific problematic or abused substances with a much more serious risk profile (including alcohol, heroin/opiates, and cocaine).  The diagnoses of my medical cannabis patients  (see USES/INDICATION above) are consistent with the bulk of my medical practice diagnoses. 


Symptoms are subjective phenomena by definition, and as such are difficult
to evaluate. Symptoms include, but are not limited to: fatigue, insomnia, 
depression, anxiety, nausea, vomiting, anorexia, elimination problems, and 
breathing difficulty.
 The control of symptoms and the alleviation of symptom distress are some of
 the most important therapeutic uses of cannabis. Both the alleviation and
the control of symptoms remain areas in which further research is needed 
(Grant, 1992). The need for additional research on symptom management is compounded by the lack of research and standards for the use of cannabis therapies. Legal
 disapprobation, restrictions on the opportunities for clinical research
 intrinsic to cannabis’ status as a Federal Schedule I Controlled Substance, 
and a long historic gap in the accumulation of clinical writing on cannabis 
therapeutics since criminalization in the 1930s have resulted in there being
 relatively little clinical literature from which we can seek guidance.


The Medical Board of California (MBC) and the California Medical Association
(CMA) have a “working group” drafting guidelines, but seven years after  the
 therapeutic use of cannabis was legalized, there are no practice standards
 other than what is usually expected of any clinician in the course of his or
 her practice.

 “Any physician who recommends the use of marijuana by a patient,” according
to the Medical Board’s July 2003 Action Report,  “should have arrived at 
that decision in accordance with accepted standards of medical
 responsibility, i.e., history and physical examination of the patient;
 development of a treatment plan with objectives; provision of informed
 consent, including discussion of side effects; periodic review of the
 treatment’s efficacy and, of critical importance, proper record keeping that
 supports the decision to recommend the use of marijuana.  However, the Board
 recognizes that these principles may require further elaboration to take
 into account the factors that may affect the physician-patient relationship 
in this context.”

My Practice and Standards


I have developed (and continue to refine) standards for the recommendation
 of medical cannabis in my own practice, reflecting my quarter century as a 
Board certified Family Physician providing primary health care. These are my
 own standards and should not be construed as criteria for any other
 physician practicing within the scope of his or her training and license.

General requirements


1. The patient should have a current source of primary care -a Primary Care
Provider or PCP- whom he or she sees regularly.

2. The patient should be seen regularly for the serious illness or symptoms
 for which medical cannabis is used, by either the PCP or by  a specialist, 
chiropractor, or other health practitioner of the patient’s choice.

These requirements accomplish two important objectives:


* Affirming that the patient has access to primary care.

* Clarifying my role as a consulting physician, and not the primary care
practitioner (a common misunderstanding).

Even if the serious illness or symptom is stable, I advise the patient to 
see his or her physician yearly, to review and update the history and 
physical.
 I generally describe this requirement to the patient by saying: “I don’t
want to be the only physician who is aware of your illness or symptom, since 
I am NOT your primary care practitioner.”
 My medical cannabis evaluation is a medical-legal consultation, and is not 
to be confused with the provision of primary care.


Phone screening


Patients calling for a medical cannabis evaluation are screened by phone to
 make sure they understand my requirements prior to being given an initial
 appointment, and to eliminate those who clearly do not qualify.

Pre-appointment


A 45-minute appointment is scheduled for new patients, or 30 minutes for
annual re-evaluations. The patient is mailed a detailed questionnaire, along
 with release forms to obtain records that will be required for the visit. 
The patient must fill out  the questionnaire in advance of the visit, and
 must request or bring medical records related to his or her serious illness.

Appointment


The medical cannabis evaluation is conducted in a face-to-face office visit,
 which includes the collection of relevant history, problem-specific physical
 exam, and review of the completed questionnaire and outside medical records.
 A written summary of the patient’s interview and history is completed for
 the patient’s chart. 
All of these data are assessed for indications that cannabis may be of
 benefit for the patient’s symptoms or problems. 


Pros and cons of medical cannabis use are discussed with the patient, and
informed consent documents are reviewed and signed. Patients are advised that they should continue to assess the benefits that they receive from medical cannabis, and should continue its use only if it continues to benefit their symptoms.

Based on all of the above, a decision is reached on whether or not to recommend cannabis to the patient. Limited approval -for three months or less- may be given in cases where there exists some documentation or physical evidence of a serious illness for which cannabis might be beneficial, but more recent records are required and/or expected to arrive.

Follow-up

Appropriate follow-up appointments are arranged for patients receiving recommendations. Yearly re-evaluation is a minimum.

More frequent follow-up visits may be required in certain circumstances, such as in some psychiatric diagnoses and some mood disorders, especially if the patient is not receiving ongoing psychiatric care. In this instance, I may require the patient to return with a family member or close friend to corroborate that patient does better with cannabis than without it.

Patients are to continue regular follow-up with the PCP and/or specialist for the serious illness or symptom for which the patient uses cannabis medicinally. At yearly renewal re-evaluation visits,  I expect the patient to bring in documentation that his or her primary provider is aware of the serious illness or symptom, and is seeing the patient for re-evaluation at least yearly.

Forms

I have developed the following forms for use in conducting medical cannabis
evaluations:

• Consent to assume risk for medical marijuana.
• A questionnaire (adapted from the questionnaire developed by the California Cannabis Research Medical Group)
• Recommendation/approval form

If a 12-month recommendation is provided, it is dated to expire on the last day of the month, to allow the patient a one-month window to be re-evaluated in their anniversary month.  Lately I have embossed the original recommendation with my seal, and  added small lettering on certificate that says “original is embossed.”  The embossing limits the reproducibility of the original. I began doing this after finding that a patient had altered his original certificate. (An extremely rare occurrence.)

Safety

Regarding safety, U.S. Administrative Law Judge Francis L. Young in September, 1988, after reviewing all the evidence on rescheduling cannabis from Schedule I to Schedule II, stated: “In strict medical terms marijuana is far safer than many foods we commonly consume. For example, eating ten raw potatoes can result in a toxic response. By comparison, it is physically impossible to eat enough marijuana to induce death.  Marijuana, in its natural form, is one of the safest therapeutically active substances known to man.  By any measure of rational analysis marijuana can be safely used within a supervised routine of medical
care.”

Limitations

Significant limitations on my discussions with medical cannabis patients are imposed by  federal government requirements or threats.

Experienced medical users will know how to titrate their dosage to achieve the desired effect

For example, I don’t suggest an amount of cannabis to use unless it’s to suggest “less” or a safer method of ingestion for harm reduction/risk minimization purposes.

Experienced medical users will know how to titrate their dosage to achieve the desired effect. In my experience, medical cannabis users consume widely varying amounts.  (The handful of patients who remain in the Federal IND program, which supplies cannabis to patients, receive six pounds per year in tinned, pre-rolled cigarette form.)

Nor do I discuss the locations of dispensaries or how to obtain cannabis. If asked, I explain that federal law prohibits my doing so. Because accurate information is vital to health and patients should always have access to accurate information, I make available a list of resources other than dispensaries through which they can learn more. These include:

* California NORML’s website

* Americans for Safe Access

* The Oakland Cannabis  Buyer’s Cooperative (which also
provides patients with a photo ID that is easier to carry in one’s wallet
than my full-page recommendation form).

I don’t sign any forms from dispensaries, and I don’t sign caregiver forms. The designation of a caregiver is not a medical decision, but is determined by agreement between the patient and the caregiver, in accordance with California law.

Documentation – Pros and Cons

There is a wide range of acceptable standards in medicine. Some doctors have been criticized for not requiring documentation of diagnosis when they approve cannabis use. Others feel that the requirement creates unnecessary barriers for patients. My arguments for requiring documentation include:

* It is common in other situations in health care.
* It enhances patient protection, both medical, legal and financial.
* It gives me more confidence that, if called upon to do so, I could successfully defend a patient’s appropriate medical use in a court of law. If law enforcement calls me to verify compliance with Prop 215, I am able to say:  “Not only did I assess the patient, but I have independent documentation of the diagnosis for which the patient uses cannabis.” In most cases, law enforcement officers have been polite and replied something to the effect of: “Thank you, doctor, we just wanted to make sure it was a valid recommendation.”

The following arguments have been made against requiring documentation:

* It is not necessarily consistent with the long tradition in medicine of a trusted doctor/patient relationship.
* It may imply that it is less than acceptable for a doctor to do his or her own evaluation, and determine that cannabis will or won’t benefit a particular patient.
* Records may be unavailable or difficult to obtain. Consider the situation of a patient who suffered a traumatic injury many years ago, and doesn’t have ongoing care for chronic pain. The patient has been self-treating effectively, and now wants to comply with state law. In this situation, the history and physical examination might be enough to make me feel comfortable without further documentation of the diagnosis.

Notes on Confidentiality

Many patients seek out cannabis consultants because they don’t feel comfortable disclosing to their primary care providers doctors that they have been self-medicating with cannabis. Although I do require that the patient’s primary provider or other appropriate practitioner be aware of, and follow, the serious illness for  which cannabis is used, I do not require that the patient disclose his or her medical cannabis use to these providers in all cases. The wording I generally use in explaining this is: “In a perfect world, you should be able to tell your physician everything. But unless, and until the federal government, employers and insurance companies no longer discriminate against medical cannabis users, there is valid reason not to have cannabis mentioned in your medical records.”

I ask the patient to assess whether he or she feels safe in telling their doctor “off the record”  that they’re using cannabis medicinally. If the answer is yes, I encourage them to do so. Your own doctor knows you best, and in a perfect world, one should be able to tell his or her doctor everything. I don’t accept insurance for medical cannabis consultations, nor do I recommend that the patient bill the insurance company, unless the patient is willing to have his/her insurance company see these records.

Special circumstances Some patient-care situations deserve special mention, as they present unusual complexities or problems. Should a patient’s medical cannabis use be questioned, some presentations or diagnoses are particularly likely to be challenged by school, probation or law enforcement authorities.

Psychiatric Patients

Psychiatric diagnoses, particularly if unstable, are likely to raise this kind of “red flag.”  In such cases, it is important  to have a good history of the efficacy of cannabis for the patient. Approval of the therapist is desirable; next best is a significant other who can attest to the patient’s condition being  improved by medical cannabis use.

Minors

The recommendation of medical cannabis use to minors is an area of controversy. As in all of medicine, one must make a risk/benefit assessment. The developmental needs of adolescents and children suggest that cannabis use should be discouraged, unless, as would be true in a person of any age, the medical benefit obtained outweighs the risk.  Recommendations for medical cannabis for minors should be issued conservatively, and evidence of effectiveness should be well-documented, as should be parental consent.

Elders and/or naive users

Many elders have never been exposed to a social environment in which cannabis is used recreationally. For these patients, as well as for any naive or first-time user, the psychological effects may be disturbing. The extensive report on medical cannabis prepared by the National Academy of Sciences Institute of Medicine in 1999 suggests that “for some patients-particularly older patients with no previous marijuana experience-the psychological effects are disturbing (p. 4).” In the years following the legalization of cannabis for medical use, only a small fraction of patients seeking physician approval have been cannabis-naive. At least 90 percent  of those seeking approval from CCRMG-affiliated physicians already know that, for them, the benefits outweigh any adverse effects. More naive patients can be expected to inquire about cannabis as a treatment option as favorable research results from Europe are reported in the literature.

How will the naive patient learn to use cannabis?

An additional question in relation to the inexperienced user is that of how the patient will learn to use cannabis. Who is available to teach the patient? Will an informed, experienced user be available when the patient first tries medical cannabis? In what form will the patient ingest cannabis? Does he or she understand the concept of titration of the dose? Is there a protected environment available to the patient for his or her initial and subsequent use? How should the patient be counseled about the possibility of unwanted effects? What precautions or preparation should the patient be advised to use?

Conclusions

Physicians who are considering whether to approve cannabis use by their patients must first educate themselves on the subject. Cannabis has a long, impressive history as a safe and effective medicine. Although the United States has limited studies on the benefits of cannabis, the National Institute on Drug Abuse has funded significant research into its mechanism of action. Universities and major pharmacuetical companies are conducting groundbreaking studies. Much of this research is available in: Grotenhermen and Russo: Cannabis and Cannabinoids: Pharmacology, Toxicology, and Therapeutic Potential.

My advice to colleagues, in brief:

* Practice responsible medicine, including encouraging patients to obtain appropriate follow-up of their illnesses from their primary care practitioner.
* Maintain good documentation, both of previous history and outside records, and of your own history, physical, assessment, and follow-up plan.
* Be able to explain your decision-making process in a court of law should you be called upon to support a legitimate patient, or to discuss a patient’s cannabis use with an employee health clinician.  On occasion, a question may arise as to whether a patient can perform safety-sensitive functions in the workplace.  It may be important to  document that the patient does not use cannabis in a specified time frame in relation to hours of work.

* Do not assist anyone in breaking the law.  The vast majority of medicalcannabis patients are honest and appropriate medical users under the Compassionate Use Act. (Notwithstanding the situations in which doctors have had visits from undercover agents posing as patients). I find cannabis patients to be, on the whole, as honest and forthright as patients or people in general. It should go without saying, but I will say it: No matter how convinced you may be of the relative benign-ness of cannabis, do not agree to do anything
illegal. Undercover agents have been known say to a doctor:  “I don’t have an illness, I just want to be able to smoke marijuana.” It should be clear that this is not a legitimate use of the Compassionate Use Act . There are millions of real patients to help.
