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.

Cannabis users reported the reduction of anxiety as one of the motivations for its use; on the other hand, episodes of intense anxiety or panic are among the most common undesirable effects of the drug Crippa et al , Moreover, other components of the plant can influence its pharmacological activity; in particular, cannabidiol CBD , one major non-psychotomimetic compound of the plant, has psychological effects substantially different from those of 9-THC Zuardi, In animal studies, CBD has similar effects to anxiolytic drugs in different paradigms including conditioned emotional response, the Vogel conflict test, and the elevated plus-maze test Zuardi, Using functional neuroimaging in healthy volunteers, we have observed that CBD has anxiolytic properties and that these effects are associated with an action on the limbic and paralimbic brain areas Fusar-Poli et al , a ; Crippa et al , Relative to placebo, CBD was associated with significant decreases in subjective anxiety induced by the SPECT procedure and modulated the same brain areas as the healthy volunteers Crippa et al , , As a first step to investigate this hypothesis, we used the SPST, an experimental model for the induction of anxiety.
SPST has apparent and predictive validity for SAD because the fear of speaking in public is a cardinal manifestation of SAD, and there is pharmacological evidence that the response pattern to some substances in the SPST is similar to the clinical response presented by patients with SAD Graeff et al , ; Brunello et al , We have decided to use a single dose of CBD because of ethical and economical constraints, as a first step in the investigation of a possible anxiolytic action of this cannabinoid in patients with pathological anxiety.
For instance, it is important to confirm whether CBD has the advantage of a rapid onset of action, making it particularly suitable for individuals who have episodic performance-related social phobia and who are able to predict the need for treatment well in advance.
Considering previous results from a single dose of CBD, it is expected that this cannabinoid will reduce the level of fear provoked by the SPST. A total of 24 subjects with generalized SAD and 12 HC subjects were selected by the screening procedure described below see section. To ensure the adequacy of the matching procedure, the first participant had his treatment blindly chosen between the two treatment options available; the next participant whose characteristics were matched to the first one's had his treatment drawn from the remaining option.
The groups were matched according to gender, age, years of education, and socioeconomic status. No subject had a history of head trauma, neurological illness, ECT, substance abuse, or major medical illnesses, based on a semi-standardized medical questionnaire and physical examination.
They were all non-smokers of tobacco and had not taken any medications for at least 3 months before the study. None of the subject had used marijuana more than five times in their lives no use in the last year and none had ever used any other illegal drug.
All subjects gave written informed consent after being fully informed about the research procedure, following approval by the local ethical committee HCRP No. The same amount of corn oil was used as placebo. The drug and placebo were packed inside identical gelatin capsules. Therefore, we have decided to use the highest dose of CBD previously found to have anxiolytic effects.
VAMS contains 16 items that Norris grouped into four factors. A factorial analysis performed with the Portuguese version of the VAMS also yielded four factors with similar item composition Zuardi et al , The original name of the anxiety factor was preserved, but the names of the remaining factors have been changed to fit the meaning of the items with the highest loads in that particular factor.
Thus, the present factors are: It is based upon cognitive theories that propose that social anxiety is the result of a negative perception of oneself and of others towards oneself. The scale is comprised of 10 items, rated on a likert scale from 0 strongly disagree to 5 strongly agree , which are organized into two subscales of five items each, for positive or negative self-evaluation.
The Bodily Symptoms Scale BSS was designed to detect physical symptoms that can, indirectly, influence anxiety measures Zuardi et al , It is organized into 21 items, and the intensity of each symptom is rated from 0 no symptom to 5 highest.
A computer-controlled, voltage-constant 0. Two electrodes Beckman, UK were fixed with adhesive tape. The skin conductance level SCL and the number of spontaneous fluctuations SF of the skin conductance were recorded. Heart rate HR was estimated by manually counting the pulse rate. The procedure is summarized in Table 1. After a min adaptation period, baseline measurements B were taken and followed by a single dose of oral CBD or placebo in a double-blind procedure.
Anticipatory speech measurements A were taken before the subject started speaking. The speech was interrupted in the middle and speech performance measurements S were taken. Clinical and demographical characteristics were analyzed with the non-parametric tests gender and socioeconomic level and by the analysis of variance for one factor ANOVA , followed by post-hoc Bonferroni's test for multiple comparisons age, age of SAD onset and SPIN.
For the analysis, SCL values were converted into natural logarithms logn. These delta scores were submitted to a repeated-measures analysis of variance repeated-measures ANOVA , analyzing the factors of phases, groups, and phases by groups' interaction.
In the case where sphericity conditions were not reached, the degrees of freedom of the repeated factor were corrected with the Huynh—Feldt epsilon. Whenever a significant phase by group interaction occurred, comparisons among the groups were made at each phase using a one-factor ANOVA followed by multiple comparisons with the Bonferroni's test.
The clinical and demographical characteristics of the subjects are shown in Table 2. No significant difference was observed between the two groups with SAD. Changes in Visual Analogue Mood Scale VAMS factors induced by simulated public speaking test SPST , measured in 12 social anxiety patients who received cannabidiol , 12 social anxiety patients who received placebo and 12 healthy controls.
