Advancing a smart CBD cancer therapy approach with smart biomaterials presents a number of advantages toward enhancing therapeutic efficacy. First, the sustained delivery of CBDs via this approach will allow for prolonged exposure of the tumor cells to CBDs with expected enhanced effectiveness in tumor cell kills as seen in our initial results.
Highlighting the viability of such a sustained delivery approach, the US Food and Drug Administration FDA has approved biodegradable disks infused with carmustine for the treatment of brain tumors 27 for greater effective treatment outcomes. Second, the in situ delivery afforded using smart biomaterials allows direct delivery of CBD payloads to the tumor subvolume while minimizing off-target toxicities, as seen with other delivery approaches like oral or intravenous administration.
This could allow for reducing the dose of CBDs used, to further minimize any potential toxicities or side effects which have so far limited clinical translation.
CBD receptors are not located in the brainstem areas which control respiration and, therefore, lethal overdoses from CBDs are not common 8 , Nevertheless, there are CBD receptors in other tissues throughout the body, which may lead to toxicities or adverse effects such as tachycardia, hypotension, conjunctival injection, bronchodilation, and decreased gastrointestinal motility.
Site-targeted delivery via SRBs could minimize such adverse effects as well as the psychoactive effects that have limited clinical translation efforts. Ongoing work is focusing on demonstrating this expected toxicity advantage in a large cohort study.
A limitation of the current study is the short-term investigation on the survival. This is partly due to an initial focus to explore and demonstrate feasibility to inform further studies. With view to clinical translation, further investigations will build on the current work for longer term survival studies employing CBD-loaded smart biomaterials with and without RT. This will also include investigations of other CBDs besides CBD that have demonstrated potential as anticancer agents but have not been rigorously tested, or have been limited by off-target toxicities, which may be minimized with the use of SRBs.
The multifunctional SRBs will be able to ensure geometric accuracy but also sustainably deliver potent CBD payloads directly to the tumor with the anticipated benefits of greater therapeutic efficacy and minimal toxicities.
In the previous clinical trial on brain tumors 3 , CBDs had to be repeatedly administered. Our approach could allow for sustained delivery, which will obviate the need for repeated administration and be more convenient for patients. Illustration of innovative approach with potential to significantly enhance therapeutic efficacy using cannabinoids CBDs. A Currently used commercially available inert radiotherapy RT biomaterials, e.
Such replacement would come at no additional inconvenience to cancer patients. Once in place the SRB can be activated to sustainably release its payload as the polymer coating degrades for greater effective tumor cell kill working in synergy with RT as highlighted by our study results.
The use of smart RT biomaterials for sustained delivery could also integrate the use of NP drones 12 loaded with CBDs that can bind specifically to tumor cells to deliver their potent payloads, enhancing tumor cell kill with minimal off-target distribution. The drone technology could also be designed to target CBDs to CB1-type receptors expressed on the peripheral terminals of nociceptors around the RT planning target volume for CBD-induced analgesia. It has been shown 29 that CBDs mediate analgesia largely via peripheral type 1 CBD receptors in nociceptors, so such an approach with sustained delivery could also help in pain management for cancer patients.
In the US, an increasing number of states have now legalized the use of medical cannabis. This trend has also spread internationally, with more countries recognizing the medicinal components of cannabis and legalizing medical use.
Unfortunately, medical cannabis research has been lagging in animal or human placebo-controlled studies addressing barriers to clinical translation. Viable pathways to clinical translation for cancer treatment should include combination approaches or smart CBD cancer therapy that leverages the antitumor effects of CBDs with high therapeutic efficacy and minimal side effects. Altogether, our results offer an approach for leveraging the antineoplastic activity of CBDs to achieve enhanced therapeutic efficacy during cancer treatment with the possibility of addressing toxicity concerns that have hampered clinical translation efforts.
The potential for using smart RT biomaterials, which integrate enhanced tumor cell killing when combining CBDs with RT, and delivery with smart biomaterials, provide a promising pathway for clinical translation. To this end, ongoing work is investigating such SRBs loaded with CBDs, which could simply replace currently used inert RT biomaterials during image-guided RT, all at no additional inconvenience to cancer patients.

While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. To date, there is no evidence of public health related problems associated with the use of pure CBD.
CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. Currently, many people obtain CBD online without a medical cannabis license. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit. In numerous studies, CBD was able to reduce the number of seizures, and in some cases it was able to stop them altogether.
Videos of the effects of CBD on these children and their seizures are readily available on the Internet for viewing, and they are quite striking. CBD is commonly used to address anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.
CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat.
More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control. Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does.
A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So you cannot know for sure that the product you buy has active ingredients at the dose listed on the label.
In addition, the product may contain other unknown elements. Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not.
We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Should one take as gospel the equivalencies between CBD and Grapefruit juice?
Omeprazole is pretty safe, by and large; I think the biggest concern with CBD would be with medications where an altered, irregular dosage could be dangerous, such as blood thinners….
I suffered two concussions within a space of 7 weeks: That was about 18 months ago and I still suffer from post-concussion syndrome, which is barely tolerable. Hyper-sensitivity to light and sound, exhaustion, some dizziness, some cognitive impairment. I hesitate to try anything that might further impair my cognitive function but I am willing to give cannabis a try now that it is legal in Canada.
There is some evidence that cannabis is neuroprotective, and can help protect against Traumatic Brain Injury: It looks like if one has THC in their system prior to the trauma, some of the damage might be mitigated. Am I wrong on this? I just started cbd oil and want to learn everything I can about it. I need some clarification here. However, I do want to know,what you base these claims on?
Thank you for your questions. Marijuana and hemp are two extremely different strains of the same cannabis sativa plant that have been bred over thousands of years to have entirely different purposes. Hemp is not the male version of the marijuana plant. They both contain CBD. Any medicine can have different effects on different people. For example, Benadryl makes some people sleepy yet can make others wide-awake. So, it is not inconsistent for a particular medicine to cause a symptom in one person and to help alleviate it in another.
I can concur based on real time experience with my Mother who is bed bound with an irreparable fracture to her hip prosthesis. She also eats gluten free muffins containing the oil.
She thoroughly enjoys her alternatives and requests them regularly. Thank you for your comment. It is fantastic that she is able to reduce her use of opioids.
For certain conditions, such as Shingles and Spinal Stenosis, some amount of THC is needed to effectively relieve the pain.
In regards to CBD eliminating pain, it depends on what level of pain the patient starts with. In the best case scenarios, my patients have completely eliminated the use of opioids and just use CBD on an as needed basis to manage their pain.
Thank you for your thoughts. Cannabidiol may partially normalize alterations in parahippocampal, striatal, and midbrain function associated with the CHR state. As these regions are critical to the pathophysiology of psychosis, the influence of CBD at these sites could underlie its therapeutic effects on psychotic symptoms.
I am 81 and started the CBD drops night and morning. I sleep better and no longer suffer the excruciating pain from diverticulitis. I think it is helping.
