Welcome to GreenBridge Medical

Up until this past year, it has been impossible to help patients using CBD, as it had nearly been bred out of the world of cannabis plants. Of course, no one knew about CBD, but everyone was growing for the stoniest weed; hence, CBD which is essentially non-psychoactive, was nearly lost. In the past two years, more and more rich CBD strains are turning up. This is in part because we know we should be looking for them AND we finally had laboratories that would accurately let us know how much of which cannabinoid was present. The Cannabinoids are the approximately 200 or so three chain molecules such as THC, the most well known one and most psychoactive one. So, the plant in the past always contained CBD – remember it all started with Hemp!

So, now we have gardens of CBD containing clones and plants with varying amounts and ratios of THC and CBD. In general, the higher the CBD/THC ratio, the less psychoactive the plant, or it’s derived medicine possess. The more the THC, the more the psychoactivity, however, there are several caveats:

1. We really don’t know for certain the relationships between levels of THC or CBD as opposed to the ratio of the two

2. There are over 100 Terpene molecules in the plant. For details see my blog on Terpenes. They are the molecules that give each strain of cannabis, it’s flavor and scent and character. Additionally, many of the Terpenes posses psychoactive effects both on the typical cannabis brain receptors (the CB1 receptors) ¬†as well as having effects on other receptors.

It is the combined effects of the cannabinoids, terpenes and perhaps another 200 molecules all working together and carefully balanced in nature that we are now referring to as “The Entourage Effect”, coined by Dr. Ethan Russo.

So, going forward in the next few months, more tinctures with tested, certified and labelled CBD/THC and Terpenes, as well as mold and pesticide testing, will be appearing on the market. It is very difficult to predict the effect of a tincture based upon whether it is from a Sativa or Indica plant. Clearly, it is the so-called “Entourage” effect of all of these molecules working together that determine how a cannabis product will effect the patient. In addition, every patient is different. So, as more and more tinctures appear in collectives, you should try them. They will be marked with a Psychoactive Scale. This has been suggested by a number of Cannabis specialists and is a scale from 0 – 10. A value of 0 means there is no psychoactivity, or virtually none. The tincture or capsule or other certified cannabis medicine will have it’s expected effects for anxiety and pain, but without any “stony” feeling at all. A 5 would be in the middle and a 9 or 10 will be extremely psychoactive.

  1. This type of insomnia is something I deal with on a daily basis. Patients with the worse sleep issues have less issues falling asleep, as they are exhausted, but they don’t stay asleep and classically awaken at 1 AM, 3 AM or 5 AM and remain awake for several hours between 1 AM and 7 AM. It is tortuous.

    I believe that it is worthwhile to have a consult, either in person, if you live nearby Santa Monica, CA or by phone at 310-393-0640

    Hello Dr. Frankel,
    I’m a 29 year old mother of 2 who has suffered from insomnia for about the last 8 years. For the last 3 years it has became very chronic & refractory to everything. I literally have not slept an entire night in those 3 years. The most I can sleep is 0-4 scattered hours a night (sometimes I’m up for day). I have seen every single type of specialist, been on over 20 medications, have had 2 sleep studies, CT, MRI, tried hypnosis, acupuncture, follow good sleep hygiene every night, and doctor’s can’t find what is wrong. I don’t suffer from depression or anxiety. I’m desperate to get the help I need for a better quality of life. I would like to get treated by you with CBD/THC but it’s not legal in Texas and I’m also a health care provider and afraid to loose my license. Do you have any suggestions for me?

    Thank you for your time.

  3. We often have good luck with dosed extracts or capsules for neurogenetic pain. I would suggest setting up a phone or in person visit. There are a number of details that are very important.

    My husband suffers from extensive nerve damage in his abdomen. He was put on gabapentin and tramadol. The gabapentin was difficult to get his body used to and the tramadol caused him to have a seizure. Now he is on gabapentin and norcos, which I dont like. He just began acupunture and I’ve been looking into cbd for him. Do you have a tincture you would recommend? This chronic pain is taking over his life.

  5. Anxiety and mood disorders account for nearly 40% of the patients I see every day. It is very likely you would benefit
    from a consult.

  6. Sadly, I don’t understand what you are saying/asking. :)

  7. Numb Nuts says:

    keep in mind
    not all cbd is created equal.
    there is a whole other side to CBD that is always over looked , under researched and misunderstood. meticulous efficacy testing over vast populations over countless years and you start to see the results.

    just as there is over 420 differant THC buzz/effects…… the same phenmonon occurs in both sides of the CBD matrix

    Dr. Frankel
    Have you treated anyone successfully with CBD oil for daily anxiety, panic attacks, insomnia, and depression? I just would like to know before I set up a consultation. Thanks.

  9. Gabriel says:

    Thank you for your reply. I appreciate it. I would love to come to CA and speak with you directly (or as you suggested, at least speak with you). I will also have another look through the site for the information you mentioned in the meantime. Will be in touch soon.

  10. These are all good questions, but:

    1. Are answered on my website if you just search
    2. Too much for me to write/answer again
    3. I would be happy to answer any questions in a one hour phone or in person consultation

  11. I am not sure about the scope of your question and it does not sound more business like, which is totally fine. I think if you seriously want to know what is going on with hemp and what we are doing, it might be worthwhile for you to come in to my office for an educational visit. It can also be done by phone. I wish I could sit all day and answer the hundreds of mails, etc, but…… :))

  12. Hi Dr. Frankel,

    I have been reading through your website for many days now and am greatly appreciative for the information you provide to others. It is a risky venture, but thankfully someone is helping people obtain such crucial information.

    As someone who is admittedly working with an industrial hemp-derived CBD product (NOT HempMeds, Cannavest etc.), I am curious about your thoughts on this type of product as an alternative for people who cannot easily access high CBD extracts (or believe that this is the only option) yet may benefit greatly from them. I have not found any information addressing this.

    I realize that there are many “corner-cutters” in this industry and perhaps that has left a bad taste in people’s mouths, but what about those that are doing the right thing? The ones that are spending great amounts of time and money to produce a pure, quality product that can operate through the Industrial Hemp laws in the US.

    How could they get support from people like you? If you felt comfortable with a certain product, would you be willing to share the information with others? What would be involved with working with you in a mutual effort to help others?

    I am sure this will be interpreted as a business-driven post, but I beg you to consider that it not that at all. I have spent 16 years in rehabilitation and left it behind because I too felt that western medicine was incomplete and “alternative” options were the only way to feel content in my work. So now, having aligned myself with the right company (owned and operated by the one of the foremost authorities on Hemp) and passionate about my work, I find nothing but rejection from those that seem like they want to help people (i.e. Project CBD, Shangri-la Care Collective). I can understand why they would need to establish confidence, but there is no effort at all.

    Would love any feedback from you. I greatly appreciate your time.

    Dear Dr. Frankel,

    For the past few months I have been doing extensive research into cannabis, and, more specifically CBD. I’ve read through websites, forums, and hundreds of papers on PubMed and elsewhere. Although I’ve been against cannabis prohibition for many years due to my Ron Paul style conservatism, I’m now simply amazed by the safety and countless medical applications of the many substances in marijuana. For it to remain illegal – while being arguably less toxic than caffeine and certainly less addictive – is a travesty. However, there is a medical reason for my interest as well.

    Although in some ways I manage it fairly well, I suffer from anxiety and OCD. Along with this, there is some depression. Mostly though, I’m at the point in my life that I realize I need to find some way to eliminate or at least reduce these symptoms. To be blunt, I’m tired of feeling so much pressure and anxiety and so little happiness. The continual checking and illogical, intrusive thoughts of OCD only frustrate me even more.

    In the past I’ve tried a couple perscription medications that offered limited relief and significant side effects. To try and rebuild my hippocampus, I’ve started exercising in the form of walking and running. In the process, by dieting as well, I’ve lost 60 pounds in the last year (down to 180 from at least 240). I’ve discovered after a very intense run that pushes me to my limit, I will have a few hours of 80% relief. The relief then starts to fade. It is simply not practical to push so hard every day due to the stress it puts on my knees and legs.

    Now, back to CBD. I have done a lot of research, but I have yet to talk to an actual medical professional who deals with patients that utilize it. So I have a few questions.

    1 – In medical papers, CBD is almost always administered in doses that seem higher than your recommendations. For example, when treating humans with schizophrenia, dosages from 400mg to 1200mg a day were administered. The same is true when tested on humans for social anxiety and cognative issues. In these tests, better results seemed to be obtained with higher doses. Even in animal tests, the dose usually seems to be at least a few milligrams per kilogram. In one animal study I read, the most effective dose for arthritis was 25mg per kilogram, orally.

    Now, in the real world, are you certain the anti-anxiety effects you witness and personally experience from low dose CBD (a couple milligrams) are significant and above placebo? Please, I’m not trying to be rude. You are a doctor and an expert and know much more than myself. In my mind it is just challenging to reconcile the low doses you mention with the high doses I read about elsewhere.

    2 – What are the differences you have witnessed when it comes to anxiety between low and higher doses of CBD? Does the effectiveness increase or is there a point at which they stop?

    3 – Have you treated OCD patients with CBD? If so, what were the dosages and results?

    4 – I live in a state where recreational and medical marijuana are illegal. However, since low THC products derived from legally imported hemp seem to be legal (sold to all 50 states straight from Amazon), I’m considering trying to find such a source of legal hemp oil, tincture, or extract that contains CBD.

    For someone in my situation, what CBD product would you recommend? My main concern is purity (that is was produced in a clean manner without toxic solvents) and that the concentration of CBD for the price is good. I’ve thought about Dixie Dew drops (derived from hemp), but do you think there is a better product on the market obtainable by someone in a very red state?

    I appreciate any advice you can offer. Thank you for all your work supporting medical marijuana.

  14. Heather Brown says:

    I just wanted to thank you for your extremely valuable consult with me and my friend about the uses and properties of these new varieties of medicinal plant. Have already changed the way I use the medicine and had some remarkable changes already. Thanks for all of the referrals and resources. You have given me real hope for my health and wellness in the future (something no doctor has ever done for my condition)

  15. I have had a lot of experience with treating cancer with cannabinoid medicine in humans. As I am not a Vet, I have not treated any dogs.

    At the same time, in general, the endocannabinoid system in all mammals is the same and tumor responses that we see in many research protocols are based upon animal research. In fact, EVERY medication I know has gone through animal testing.

    So, I would expect the same results.

    Hi Dr. Frankel (or Whom It May Concern):

    Recently, I read with great interest a piece posted to Mercola.com entitled ‘The Benefits of Medical Cannabis’ (http://articles.mercola.com/sites/articles/archive/2014/03/09/medical-cannabis.aspx?e_cid=20140309Z1_US-CA_PRSNL_Art_1&utm_source=prmrsnl&utm_medium=email&utm_content=art1&utm_campaign=20140309Z1_US-CA&et_cid=DM40769&et_rid=450272140), in which your work to prepare CBD extract to treat cancer, among other various ailments, is discussed. My family’s beloved, nearly nine year-old, Golden Retriever, Marley, is afflicted with a highly aggressive form of cancer known as hemangiosarcoma of the heart. I am curious to know if you have any experience in preparation of CBD extracts for use in the treatment of cancers seen generally in dogs? While we are working with a skilled homeopathic veterinarian whose primary specialty is cancer treatment (www.charlesloopsdvm.com), as well as following much of the guidance offered by another inspiring cancer specialist veterinarian (http://pathwithpaws.com/blog/2013/04/18/hemangiosarcoma-of-the-heart-in-dogs-holistic-options/), it would be great to add high potency CBD hemp oil to Marley’s regimen, if you believe it could be of benefit to him.

    Thanks in advance for your thoughts.

    Devin Evert

  17. It is best to just call the office. :) 310-393-0640

  18. Please call the office at 310-393-0640

  19. Marsalee Forrestar says:

    I am interested in a potential appointment but would like to know the charge, please. I am on a limited income. Thank you.

  20. I believe it would be worthwhile setting up a visit with me

  21. Probably 90% of the patients who use dosed and consistent CBD rich medicines are greatly benefitted by CBD rich extracts. Perhaps consider a phone consultation with me?

  22. The best thing to do would be to setup a 60 minute phone consultation. Decide what type and dose might be best and then of course help figure out a way to get the medicine

  23. Wynn levitt says:

    I have a 37 year old daughter with cerebral palsy and Lennox gaustau symdrome. She had a corpus collosum in 2000 and vns in 2013 with multiple anticonvulsants throughout her life. She still has seizures on a daily basis. We live in Alaska where medicinal cannibis is legal but no outlets here to purchase. I’m very anxious to start her on cbd’s , have read a lot information but still unsure where to start. I would like to consult with you and see if you could give some guidance as to which product to start with. I ordered some through bluebird with a 24% of cbd and am waiting for it to arrive in the mail. I have heard of the charlottes web strain but it appears there is a waiting list and chanda would need to be a Colorado or California resident to get on the list.??? I hope we can speak together soon. Thank you, Wynn

  24. Lindsay says:

    Has any of your patients been cured or helped by the use of CBD oil for anxiety, panic attacks, insomnia, OCD, and depression. Thanks!

  25. charlotte says:

    I am fighting ms, and I’ve read and seen shows where cannabis oil help. I am sure the oil can help with ms. Please assist me in getting the oil. Where can I get it? Whatever it can do will make me happy. I live in LA

  26. Patients taking any of the CBD extracts on the market will test positive even for the tiny amount of THC

  27. Please call the office to setup a phone consultation. I understand your frustration and would like to help. I just know that a two minute phone call will not be helpful. I do provide phone and Skype phone “informational” consults. Our office phone is 310-393-0640

  28. This is a bit too much for an email answer, but we have had some pretty good results with both tinnitus and vertigo. Give my office a call if you wish to setup a phone or in person consultation. 310-393-0640
