Tricky is an understatement. It appears that it was the DEA that put it on schedule 1 in Dec. DEA" legal case 14 years ago, it is being challenged again? What I don't understand is how it can illegal, yet sold nearly everywhere, at the same time? It is illegal and legal at the same time?
A kind, generous friend gave my wife a bottle to help with her RA symptoms while we were vacationing in Canada. She will not use it until we find out if it is legal to possess and her doctors give her the go ahead, but we would be interested in the test results.
I have been a Consumerlab member for years. We will consider that. We have received many suggestions this week of products. He has arthritis and a bad heart murmur.
At first it really seemed to help with his pain and he was much more mobile. After a few weeks he started getting more lethargic and not eating. I did some research and discovered it should not be given along with any medications that are metabolized by the liver. It causes these meds to build up in the body so he was exhibiting symptoms of overdose of his heart medications. I stopped the CBD oil and he got started eating and seemed to feel better. Give with caution if your pet is on other meds.
You can read the manufacturer's claims. I'm 87 and found the CBD oil does relieve my aches and pains, and clears my mind. The results aren't like prescription drugs; they aren't usually immediate. People have differing results. There are recommendations for the amount to take and you are wise to heed them.
I use Blubird Botanicals and ran out a couple days ago, and I can definitely feel the difference. I expect a new order tomorrow. For me, the expense is worth it. There are several online sites where you can receive much information. Beware of the Pure Natural brand. It offers a free trial, but in the small print you are signing up for a monthly supply at full cost.
The BBB has a report on this. Please note that hemp oil may be made with hemp seeds or other parts of the plant. Commonly hempseed oil is called hemp oil. I meant to say that CBD oil isn't made from the seeds, from what I've read. I am being ask about CBD frequently now. This is what one of my clients had to say about it. I bought it at the Remedy Pharmacy in Torrance on Hawthorne Boulevard, but you can also order online. I didn't have incredible overnight success with it like the women at the seminar we went to did, but I am having less pain and sleeping better.
I don't know if it's a true change or just placebo effect, but I'll take it either way: The pain is along, above and below the scar area. In Az medical marijuana is legal with a card from a physician. I didn't see any relief with it.
I get instant relief for anywhere between a half and hour to a couple of hours. My pain is reduced substantially while waiting for the pain pill to take effect. I'm NOT recommending anything here, just letting you know how it helps me. By the way, I'm 71 and have been with this pain for over 5 years since the surgery. It is some help. I have ordered Liberty Lixir from Liberty Lotion because other fm sufferers have raved about it.
Anyone used this product before? Her tumor did not grow and she had better capability with her ADLs. The FDA is protecting money interests of Big Pharm, and until they can corner the product for that purpose, they will continue imposing mandates on legal sales. This friend gets if from a dispensary in LA for his grandmother - 90 yo. She is able to walk again.
CBD lessens my pain from fibromyalgia and bad arthritis pretty much everywhere in my body. I went to a health food store and bought some capsules first. But the tincture in dropper form from the dispensary works much better. It does not affect my sleep. I was taking an opiate daily. Now I only need it maybe every 5 days or so. What could be better than than?!
I have been suffering with this condition for 7 years. I am now legally registered for medical marijuana. While expensive, it provides significant relief, better than any of my prescription drugs do. I highly recommend that anyone with Chronic Pain Syndrome consider going through the relatively easy evaluation process so that you can try products currently legally on the market. It has transformed terrified animals into calm and relaxed pets. Something seems to be working on their anxiety. I have no financial interest.
I do buy the products from a Vet. Should be available at most pet stores near you, and online. We will look into this product. The Thunder Shirt was heavily promoted and advertised so we bought one for him and tried it for a couple years. It calmed him a little bit but he would still remain panicked from the noise. Its manner of fastening provides a more secure and tight fitting compression of the animal's chest.
When the fireworks started he perked but didn't even whimper and remained calm throughout the couple hours they lasted. It solved all his problems for fireworks and thunderstorms in one wearing. We tried them on our cats.
One accepted it and calmed down. The other one freaked out. If they were still with us , I would certainly try it for them. Looking around on the internet for genuine info on this is frustrating to say the least. Some people may have an allergic reaction to CBD oil, so it is best to try applying the oil to a small area of skin first. CBD oil shows promise as a treatment for arthritis pain. If it affects receptors in the brain and immune system in the way that researchers believe, it may reduce inflammation and pain.
However, more studies are necessary before researchers can say with certainty that CBD oil is an effective treatment for arthritis pain. There is a selection of CBD oil available for purchase online. At a time when we are trying to reduce the use of pain relievers, CBD oil can be an effective approach to managing the pain of arthritis.
However, its effectiveness will vary from person to person. Work with your doctor to sort out the right balance of CBD oil, other medications, and self-care. This may work better than the medications you have been taking.

A randomized, double-blind, crossover, placebo-controlled trial was conducted in 16 healthy nonanxious subjects using a within-subject design. The doses were selected to only evoke neurocognitive effects without causing severe toxic, physical, or psychiatric reactions.
The physiological parameters, heart rate and blood pressure, were also monitored and no significant difference between the placebo and the CBD group was observed. A case study describes a patient treated for cannabis withdrawal according to the following CBD regimen: Hepatic enzymes were also measured daily, but no effect was reported.
Naturalistic studies with smokers inhaling cannabis with varying amounts of CBD showed that the CBD levels were not altering psychomimetic symptoms.
CBD might work to alleviate disorders of addiction, by altering the attentive salience of drug cues. The study did not further measure side effects. CBD can also reduce heroin-seeking behaviors e. This was shown in the preclinical data mentioned earlier and was also replicated in a small double-blind pilot study with individuals addicted to opioids, who have been abstinent for 7 days.
One hour after the video session, subjective craving was already reduced after a single CBD administration. The effect persisted for 7 days after the last CBD treatment. Interestingly, anxiety measures were also reduced after treatment, whereas no adverse effects were described. A pilot study with 24 subjects was conducted in a randomized, double-blind, placebo-controlled design to evaluate the impact of the ad hoc use of CBD in smokers, who wished to stop smoking. Pre- and post-testing for mood and craving of the participants was executed.
Craving was assessed using the Tiffany Craving Questionnaire On day 1 and 7, exhaled CO was measured to test smoking status. Sedation, depression, and anxiety were evaluated with the MRS. At day 7, the anxiety levels for placebo and CBD group did not differ. CBD did not increase depression in contrast to the selective CB1 antagonist rimonabant. CBD might weaken the attentional bias to smoking cues or could have disrupted reconsolidation, thereby destabilizing drug-related memories.
To the best of our knowledge, no acute studies were performed that solely concentrated on CBD glycemic effects. Moreover, the only acute study that also measured CBD effect on appetite was the study we described above, comparing different cannabis strains.
Growth hormone and prolactin levels were unchanged. Compared to the healthy individuals, the cortisol levels increased less after TSST in the 32 at-risk individuals. The CBD group showed less reduced cortisol levels but differences were not significant.
Truly chronic studies with CBD are still scarce. Nonetheless, we also included these studies with repeated CBD treatment, because we think that compared to a one-time dose of CBD, repeated CBD regimens add value and knowledge to the field and therefore should be mentioned here. These results are supported by another study described in the review by Grotenhermen et al.
CBD was administered on average with three other drugs, including clobazam The coadministration led to an alteration of blood levels of several antiepileptic drugs. In the case of clobazam this led to sedation, and its levels were subsequently lowered in the course of the study. A first pilot study in healthy volunteers in by Mincis et al. Clinical chronic lasting longer than a couple of weeks studies in humans are crucial here but were mostly still lacking at the time of writing this review.
They hopefully will shed light on the inconsistencies observerd in animal studies. Chronic studies in humans may, for instance, help to test whether, for example, an anxiolytic effect always prevails after chronic CBD treatment or whether this was an artifact of using different animal models of anxiety or depression.
In a 4-week open trial, CBD was tested on Parkinson's patients with psychotic symptoms. This led to a reduction of their psychotic symptoms.
Moreover, no serious side effects or cognitive and motor symptoms were reported. No adverse effects were observed and her symptoms improved. The same positive outcome was registered in another study described by Bergamaschi et al. The respective treatment was maintained for three additional weeks. This was the case for three patients in the CBD group and five patients in the amisulpride group.
CBD treatment was accompanied by a substantial increase in serum anandamide levels, which was significantly associated with clinical improvement, suggesting inhibition of anandamide deactivation via reduced FAAH activity. In addition, the FAAH substrates palmitoylethanolamide and linoleoyl-ethanolamide both lipid mediators were also elevated in the CBD group. CBD showed less serum prolactin increase predictor of galactorrhoea and sexual dysfunction , fewer extrapyramidal symptoms measured with the Extrapyramidal Symptom Scale, and less weight gain.
Moreover, electrocardiograms as well as routine blood parameters were other parameters whose effects were measured but not reported in the study. CBD better safety profile might improve acute compliance and long-term treatment adherence. A press release by GW Pharmaceuticals of September 15th, , described 88 patients with treatment-resistant schizophrenic psychosis, treated either with CBD in addition to their regular medication or placebo.
Important clinical parameters improved in the CBD group and the number of mild side effects was comparable to the placebo group. Moreover, neurological and physiological examinations were performed, which neither showed signs of CBD toxicity nor severe side effects. The study also illustrated that CBD was well tolerated. CBD in addition to their regular epilepsy medication. Another clinical study lasting at least 3 months with children and young adults with various forms of epilepsy, who were treated with the CBD drug Epidiolex, was presented at the American Academy for Neurology in In a few cases, severe side effects occurred, but it is not clear, if these were caused by Epidiolex.
The largest CBD study conducted thus far was an open-label study with Epidiolex in patients mainly children, the average age of the participants was 11 suffering from severe epilepsy, who could not be treated sufficiently with standard medication.
Ten percent of the patients reported side effects tiredness, diarrhea, and exhaustion. After extensive literature study of the available trials performed until September , CBD side effects were generally mild and infrequent. The only exception seems to be a multicenter open-label study with a total of patients aged 1—30 years, with treatment-resistant epilepsy.
This led to a reduction in seizure frequency. It is therefore difficult to put the side effect frequency into perspective. Attributing the side effects to CBD is also not straightforward in severely sick patients. Thus, it is not possible to draw reliable conclusions on the causation of the observed side effects in this study.
This rating instrument comprised the following factors: This assessment instrument analyzes adverse medication effects, including psychic, neurologic, autonomic, and other manifestations. Using various safety outcome variables, clinical tests, and the cannabis side effect inventory, it was shown that there were no differences between the placebo group and the CBD group in the observed side effects.
The occurrence of various degrees of GVHD was compared with historical data from patients, who had only received the standard treatment. This resulted in lower resistin levels compared to baseline.
The hormone resistin is associated with obesity and insulin resistance. Compared to baseline, glucose-dependent insulinotropic peptide levels were elevated after CBD treatment. This incretin hormone is produced in the proximal duodenum by K cells and has insulinotropic and pancreatic b cell preserving effects. CBD was well tolerated in the patients. However, with the comparatively low CBD concentrations used in this phasetrial, no overall improvement of glycemic control was observed.
When weight and appetite were measured as part of a measurement battery for side effects, results were inconclusive. For instance, the study mentioned above, where 23 children with Dravet syndrome were treated, increases as well as decreases in appetite and weight were observed as side effects. However, in the safety analysis group, consisting of subjects, 10 showed decreased weight and 12 had gained weight. Both these factors were not controlled for in the reviewed studies.
This review could substantiate and expand the findings of Bergamaschi et al. First, more studies researching CBD side effects after real chronic administration need to be conducted. Many so-called chronic administration studies, cited here were only a couple of weeks long. Second, many trials were conducted with a small number of individuals only. To perform a throrough general safety evaluation, more individuals have to be recruited into future clinical trials.
Third, several aspects of a toxicological evaluation of a compound such as genotoxicity studies and research evaluating CBD effect on hormones are still scarce. Especially, chronic studies on CBD effect on, for example, genotoxicity and the immune system are still missing. Last, studies that evaluate whether CBD-drug interactions occur in clinical trials have to be performed. In conclusion, CBD safety profile is already established in a plethora of ways.
However, some knowledge gaps detailed above should be closed by additional clinical trials to have a completely well-tested pharmaceutical compound. The study was commissioned by the European Industrial Hemp Association. EIHA paid nova-Institute for the review.

Relevant Preclinical Studies Before we discuss relevant animal research on CBD possible effects on various parameters, several important differences between route of administration and pharmacokinetics between human and animal studies have to be mentioned. Open in a separate window. The reality is more complex, because CBD is lipophilic and, for example, will consequently accumulate in fat tissue. These calculations were made with the intention to give the reader an impression and an approximation of the supraphysiological levels used in in vitro studies.
CBD-drug interactions Cytochrome Pcomplex enzymes This paragraph describes CBD interaction with general drug -metabolizing enzymes, such as those belonging to the cytochrome P family. Neurological and neurospychiatric effects Anxiety and depression Some studies indicate that under certain circumstances, CBD acute anxiolytic effects in rats were reversed after repeated day administration of CBD. Psychosis and bipolar disorder Various studies on CBD and psychosis have been conducted.
Addiction CBD, which is nonhedonic, can reduce heroin-seeking behavior after, for example, cue-induced reinstatement. Neuroprotection and neurogenesis There are various mechanisms underlying neuroprotection, for example, energy metabolism whose alteration has been implied in several psychiatric disorders and proper mitochondrial functioning.
Immune system Numerous studies show the CBD immunomodulatory role in various diseases such as multiple sclerosis, arthritis, and diabetes. Cell migration Embryogenesis CBD was shown to be able to influence migratory behavior in cancer, which is also an important aspect of embryogenesis.
