Aug 24, 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. Cannabidiol—CBD—is a cannabis compound that has significant medical benefits, but does not make people feel “stoned” and can actually counteract the . After tetrahydrocannabinol (THC), cannabidiol (CBD) is the second-most abundant Have you ever had a prescription that warns you not to take the medicine In , The Hebrew University of Israel published a study that documented the.

Cannabidiol can be sourced from both marijuana plants and hemp plants, which are legal in most countries as they contain minor amounts of THC. The phytocannabinoid cannabidiol CBD , is a non-intoxicating molecule that results from the heating, or decarboxylation , of cannabidiolic acid, or CBDA. As popular as CBD has become in both the cannabis community and mainstream consumerism, its natural precursor, CBDA, is one of unique cannabinoids found in cannabis.
To date, scientists have discovered more than a dozen different mechanisms of action, or ways that CBD affect us. Much more research is needed to fully understand the mechanisms by which CBD relieves ailments such as anxiety and seizures. CBD directly interacts with a number of proteins in the body and central nervous system, a few of which are components of the endogenous cannabinoid system.
CBD binds to all of these, and many of its anti-inflammatory and pain-relieving effects may occur through these pathways. It also acts at the peroxisome proliferator activated receptors PPARs , which halt the proliferation of cancer cells and convey neuro- and cardioprotection.
CBD has powerful effects on the liver as well. Have you ever had a prescription that warns you not to take the medicine along with grapefruit? CBD does the same thing , so it is wise to discuss your medication regimen with a doctor or pharmacist before engaging in CBD therapy. This phenomenon of cannabis-derived molecules working better together than they do in isolation is commonly referred to as the entourage effect.
Consumers report using CBD for a huge variety of health and wellness reasons, but a lot more research is needed to determine which symptoms and ailments it works best for. Currently, there are more than 40 clinical trials enrolling patients to examine the effectiveness of CBD for a variety of diseases, including substance use disorder, chronic pain, post-traumatic stress disorder PTSD , depression, schizophrenia, and many others. Most importantly, CBD is incredibly safe, and not addictive.
The most common side effect of high-dose CBD is sleepiness. Some very good medical and scientific research has been conducted for the following conditions. Inhibiting the absorption of this compound shunts excess quantities into the bloodstream that in turn reduces pain. In both humans and animal models, CBD has been shown to have a variety of anti-inflammatory properties.
Clinical trials have shown that CBD is effective at reducing seizures in children, and the FDA is likely to approve Epidiolex, a pharmaceutical-grade version of CBD for this use, in summer Not enough studies have been conducted to understand this relationship fully. In , researchers conducted a comprehensive review to get at the heart of CBD and its intervention of addictive behaviors. These researchers gathered 14 studies, nine 9 of which involved animals, while the remaining five 5 involved humans, to find that CBD may indeed have therapeutic properties on opioid, cocaine, and psychostimulant addiction.
Further, studies heavily suggest that CBD may also be beneficial in the treatment of marijuana and tobacco addiction. One reason that CBD may be effective as treatment for addictive disorders is its ability to ease the anxiety that leads people to crave drugs like heroin. At sufficient doses mg , CBD can alleviate situational anxiety, such as public speaking. Interestingly, cannabis cultivars, or strains, that are high in CBD and low in THC are better than other cultivars for alleviating depression.
But when used over a long period of time, any kind of cannabis could make depression worse. There is a massive amount of scientific research being done on CBD right now, and we are likely to see many medical breakthroughs in the next decade.
It found that extract taken from whole plant CBD-rich cannabis is therapeutically superior to single-molecule extract. The scientists behind this study noticed that science had been utilizing pure, single-molecule CBD, which resulted in a bell-shaped dose-response curve.
The study from Israel essentially documented the synergistic effects of whole plant cannabinoid profiles; as noted above, this is the entourage effect. The difference here, however, is that this most recent study dove into what extent whole-plant CBD can be more therapeutic than single-molecule CBD extract.
Although both hemp and marijuana are cannabis, hemp produces less than 0. This means that producing a single 10 mL dose of CBD would require the cultivation and extraction of far more hemp than it would from whole-plant marijuana; thus raising the risk of exposing users to more contaminants. Also, CBD derived from industrial hemp lacks the the incredibly diverse profile of different cannabinoids and terpenes found in whole-plant marijuana.
CBD derived from hemp boasts a greatly weaker entourage effect. Federal law in the United States prohibits the use of hemp leaves and flowers to make drug products. In this case, the differences between industrial hemp and whole-plant marijuana are far less significant. Consumers should be aware that a handful of hemp products on the market pay lip service to governmental regulations by labeling themselves as hemp, despite containing cannabinoids and terpenoids. A potent pain-reliever, Cannatonic hails from Spain and stands as one of the earliest cultivars to be bred for its high CBD content.
This cultivar is a cross between MK Ultra and G13 Haze, and it helps relieves anxiety, muscle spasms, pain, and migraines while providing uplifting energy. Cannatonic tends to relax and loosen muscles without locking users to their couches. This cultivar was bred by crossing classic landraces from Nepal, Switzerland, and Thailand. It smells of a fresh pine forest dotted with hints of cherry. Harlequin helps mute pain and stress without fogging the mind.
This cultivar typically sports a 1: This Sativa-dominant Hybrid smells of musky diesel but refreshes the soul like a warm cup of tea. This cultivar is named after the cannabidiol pioneer, Lawrence Ringo. Some evidence has shown that THC might be useful in treatment of anorexia and behavioral symptoms in patients with dementia. The most common adverse events reported during cannabinoid treatment in older adults were sedation-like symptoms. Despite limited clinical evidence, a number of medical conditions and associated symptoms have been approved by state legislatures as qualifying conditions for medicinal cannabis use.
Table 1 contains a summary of medicinal cannabis indications by state, including select disease states and qualifying debilitating medical conditions or symptoms. A total of 28 states, the District of Columbia, Guam, and Puerto Rico now allow comprehensive public medical marijuana and cannabis programs.
Medicinal Cannabis Indications for Use by State 10 , 60 , Table adapted with permission from the Marijuana Policy Project; 60 table is not all-encompassing and other medical conditions for use may exist. The reader should refer to individual state laws regarding medicinal cannabis for specific details of approved conditions for use.
In addition, states may permit the addition of approved indications; list is subject to change. Some of the most common policy questions regarding medical cannabis now include how to regulate its recommendation and indications for use; dispensing, including quality and standardization of cultivars or strains, labeling, packaging, and role of the pharmacist or health care professional in education or administration; and registration of approved patients and providers.
The regulation of cannabis therapy is complex and unique; possession, cultivation, and distribution of this substance, regardless of purpose, remain illegal at the federal level, while states that permit medicinal cannabis use have established individual laws and restrictions on the sale of cannabis for medical purposes.
In a U. Department of Justice memorandum to all U. Cole noted that despite the enactment of state laws authorizing marijuana production and sale having a regulatory structure that is counter to the usual joint efforts of federal authorities working together with local jurisdictions, prosecution of individuals cultivating and distributing marijuana to seriously ill individuals for medicinal purpose has not been identified as a federal priority.
There are, however, other regulatory implications to consider based on the federal restriction of cannabis. Medical cannabis expenses are not reimbursable through government medical assistance programs or private health insurers. As previously described, the Schedule I listing of cannabis according to federal law and DEA regulations has led to difficulties in access for research purposes; nonpractitioner researchers can register with the DEA more easily to study substances in Schedules II—V compared with Schedule I substances.
For example, the Center for Medicinal Cannabis Research at the University of California—San Diego had access to funding, marijuana at different THC levels, and approval for a number of clinical research trials, and yet failed to recruit an adequate number of patients to conduct five major trials, which were subsequently canceled. The limited availability of clinical research to support or refute therapeutic claims and indications for use of cannabis for medicinal purposes has frequently left both state legislative authorities and clinicians to rely on anecdotal evidence, which has not been subjected to the same rigors of peer review and scrutiny as well-conducted, randomized trials, to validate the safety and efficacy of medicinal cannabis therapy.
Furthermore, although individual single-entity pharmaceutical medications, such as dronabinol, have been isolated, evaluated, and approved for use by the FDA, a plant cannot be patented and mass produced by a corporate entity. The Schedule I designation of cannabis causes hospitals and other care settings that receive federal funding, either through Medicare reimbursement or other federal grants or programs, to pause to consider the potential for loss of these funds should the federal government intercede and take action if patients are permitted to use this therapy on campus.
Similarly, licensed practitioners registered to certify patients for state medicinal cannabis programs may have comparable concerns regarding jeopardizing their federal DEA registrations and ability to prescribe other controlled substances as well as jeopardizing Medicare reimbursements. Attorney General Eric Holder recommended that enforcement of federal marijuana laws not be a priority in states that have enacted medicinal cannabis programs and are enforcing the rules and regulations of such a program; despite this, concerns persist.
The argument for or against the use of medicinal cannabis in the acute care setting encompasses both legal and ethical considerations, with the argument against use perhaps seeming obvious on its surface. States adopting medical cannabis laws may advise patients to utilize the therapy only in their own residence and not to transport the substances unless absolutely necessary. Canada has adopted national regulations to control and standardize dried cannabis for medical use. The argument can be made that an herb- or plant-based entity cannot be identified by pharmacy personnel as is commonly done for traditional medicines, although medicinal cannabis dispensed through state programs must be labeled in accordance with state laws.
Dispensing and storage concerns, including an evaluation of where and how this product should be stored e. Inpatient use of medicinal cannabis also carries implications for nursing and medical staff members.
The therapy cannot be prescribed, and states may require physicians authorizing patient use to be registered with local programs. Despite the complexities in the logistics of continuing medicinal cannabis in the acute care setting, proponents of palliative care and continuity of care argue that prohibiting medicinal cannabis use disrupts treatment of chronic and debilitating medical conditions.
Patients have been denied this therapy during acute care hospitalizations for reasons stated above. Legislation in Minnesota, as one example, has been amended to permit hospitals as facilities that can dispense and control cannabis use; similar legislative actions protecting nurses from criminal, civil, or disciplinary action when administering medical cannabis to qualified patients have been enacted in Connecticut and Maine.
Despite lingering controversy, use of botanical cannabis for medicinal purposes represents the revival of a plant with historical significance reemerging in present day health care. Legislation governing use of medicinal cannabis continues to evolve rapidly, necessitating that pharmacists and other clinicians keep abreast of new or changing state regulations and institutional implications. Ultimately, as the medicinal cannabis landscape continues to evolve, hospitals, acute care facilities, clinics, hospices, and long-term care centers need to consider the implications, address logistical concerns, and explore the feasibility of permitting patient access to this treatment.
Whether national policy—particularly with a new presidential administration—will offer some clarity or further complicate regulation of this treatment remains to be seen.
