CBD’s action within the brain and body is quite complicated. To date, scientists have discovered more than a dozen different mechanisms of action, or ways that CBD affect us. It’s very likely that the beneficial effects of CBD are a result of the total of its activation of all of these biological pathways, not a single one in particular. Much more research is needed to fully understand the mechanisms by which CBD relieves ailments such as anxiety and seizures.
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.[140] Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method).[140] A number of investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.[141]

Great quality, easy to find at nearby shop. I love the almost instant relief it brings. Was skeptical at first, never liked a tingly or cooling sensation from certain essential oils but this product is hands down the best and ill handle the icy sensation any day! Use it on my neck, back and knees, thank you for making a great accessible alternative for people!
Industrial hemp contains, by weight, far less CBD than CBD-rich cultivars such as Harlequin or Sour Tsunami. 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. Hemp is classified as a “bioaccumulator,” or a plant that naturally absorbs toxicants from the soil.
While normally I'd be slightly tripped up by little things like an overly crowded subway car or a full inbox at work, the CBD oil seems to have taken the edge off of my anxiety a bit. Rather than overthinking a sternly worded email or analyzing a social interaction, I've found it easier to recognize the irrationality of these thoughts and actually let them go (instead of ruminating on the situation). In some ways, I feel more like myself. With that said, I've still experienced some social anxiety when meeting new groups of people—I'd be interested to see what taking the full recommended dose would do.

Both Bonn-Miller and Ward stress that it's up to the consumer to be well-educated about the material they're purchasing and the research that's out there. "The companies that are creating [cannabis oils] are offering lots of claims about its use that are not necessarily substantiated by any research," Bonn-Miller said. So "I think there needs to be, from a consumer standpoint, a lot of vigilance," he added.
CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.

There is reasonable evidence from prospective epidemiological studies which suggests that cannabis use can precipitate schizophrenia in persons who are vulnerable because of a personal or family history of schizophrenia. There is also evidence that a genetic vulnerability to psychosis increases the risk that cannabis users will develop psychosis (McGuire et al., 1995; Arseneault et al., 2002; Verdoux et al., 2002). A casual relationship also has biological plausibility in that the cannabinoid and dopaminergic neurotransmitter systems interact in animals. D'Souza and colleagues (1999) have shown in a provocation study that THC produces a dose-dependent increase in psychotic symptoms under double-blind placebo conditions; and Caspi and colleagues (2005) have shown an interaction between specific alleles of the COMT allele and psychotogenic effects of cannabis. If these results can be replicated and extended, they will increase the likelihood that cannabis can be a contributory cause of psychosis in vulnerable individuals.

Oh, was I just talking about Girl Scout cookies? I prefer showers over baths—we all have an allegiance to one or the other—but we can’t ignore how many memes have come out of #bathbombs. It’s satisfying to watch them fizzle, they turn your bath into fun colors, and they claim to provide aromatherapy benefits, too. They’re also much tidier than traditional bath salt products; just chuck one in and wait!

Neuroscience and Biobehavioral Reviews. 88: 26–41. doi:10.1016/j.neubiorev.2018.03.008. PMID 29535069. This may reflect the multitude of cognitive tasks employed by the various studies included in these meta-analyses, all of which involved performing a task thereby requiring the participant to reorient their attention and attempt to solve the problem at hand and suggest that greater engagement of this region indicates less efficient cognitive performance in cannabis users in general, irrespective of their age.

The end bit is not dissimilar from what's going on with the cannabis plant itself. If you were to eat raw cannabis, it’s unlikely you’d get high, because it's mostly THCA. It's only after you apply heat that THCA transforms into THC. (Though small amounts of THCA convert to THC over time as cannabis flower cures.) Edibles work because manufacturers first transform THCA into THC with a process called decarboxylation.
Can cannabis help treat psoriasis? The active cannabinoids in cannabis may be an effective treatment for psoriasis. Research shows that they offer potential health benefits that could relieve the symptoms of psoriasis. They may be able to reduce inflammation and itching, control pain, and even heal wounds.

For many, the medical and therapeutic potential of cannabis is what makes legalizing the marijuana plant such an important political and social task. Federal prohibition has established barriers to comprehensive cannabis research in the United States. However, researchers in other countries continue to make significant contributions to our knowledge of the cannabis plant and how it affects the human body.
Of course, the #1 thing you’ll want to look out for when selecting CBD products for your pets is that the product actually contains CBD. It’s easy enough to label something as “hemp-infused” or “hemp-based”, but it’s another thing altogether to actually have the appropriate levels of cannabidiol present in order to initiate any sort of chemical/physiological change. Short of going into a whole thing about which brands and products are ‘legit’ and which are not, take a quick look at this list of FDA warning letters, which exposes a handful of companies for advertising their products as “CBD-containing”, when in fact they are not.
I have a 2.5 yr old boxer pit mix who I adopted from the shelter with auto immune problems. She suffers from anything like skin rashes to elevated liver to allergies and swelling of her little toes 🙁 What do you recommend? I don’t mind spending the money to help her be comfortable …any advice would help as I have never given her anything like this 🙂
To decide between these hypotheses, we need evidence that cannabis use preceded the psychosis; that plausible alternative explanations based on confounding can be excluded (Hall, 1987). The best evidence for answering these questions comes from longitudinal population-based studies that have assessed cannabis use before the onset of psychotic symptoms, followed the cohort over a substantial period and used statistical methods to assess the contribution of a variety of factors other than cannabis use that may explain the relationship (Macleod et al., 2004).

Cannabis for dogs is considered by many pet owners to be a therapy option for skittish dogs with high anxiety levels but current research shows CBD is effective for even more serious degenerative diseases like Canine hip-dysplasia, osteo-arthritis, Epilepsy or Cancer. Another reason people may want to offer medical cannabis to their dogs is for general pain relief–particularly in older animals who are suffering or have difficulty moving about due to advanced age. Like humans, medical cannabis’ success for animal patients depends on the proper dosage–and weight of your dog has the most bearing on determining the proper starting dosage.

What makes CBD so appealing is that it’s non-intoxicating, so it won’t get you high, though it “is technically psychoactive, because it can influence things like anxiety,” Jikomes said. Although much of the marketing blitz around CBD centers on the fact that you can take it without getting stoned, there isn’t much research looking at the effects of CBD when used in isolation, with a couple of exceptions. One is the use of CBD to treat seizures: CBD is the active ingredient in the only cannabis product that the Food and Drug Administration has signed off on — a drug called Epidiolex, which is approved for treating two rare forms of epilepsy. Animal models and a few human studies suggest that CBD can help with anxiety, but those are the only conditions with much research on CBD in isolation.


A 2015 meta analysis found that, although a longer period of abstinence was associated with smaller magnitudes of impairment, both retrospective and prospective memory were impaired in cannabis users. The authors concluded that some, but not all, of the deficits associated with cannabis use were reversible.[121] A 2012 meta analyses found that deficits in most domains of cognition persisted beyond the acute period of intoxication, but was not evident in studies where subjects were abstinent for more than 25 days.[122] Few high quality studies have been performed on the long-term effects of cannabis on cognition, and results were generally inconsistent.[123] Furthermore, effect sizes of significant findings were generally small.[122] One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions.[124] Impairments in executive functioning are most consistently found in older populations, which may reflect heavier cannabis exposure, or developmental effects associated with adolescent cannabis use.[125] One review found three prospective cohort studies that examined the relationship between self reported cannabis use and intelligence quotient (IQ). The study following the largest number of heavy cannabis users reported that IQ declined between ages 7–13 and age 38. Poorer school performance and increased incidence of leaving school early were both associated with cannabis use, although a causal relationship was not established.[117] Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency.[126]
The use of Cannabis for seed oil (Fig. 36) began at least 3 millennia ago. Hempseed oil is a drying oil, formerly used in paints and varnishes and in the manufacture of soap. Present cultivation of oilseed hemp is not competitive with linseed for production of oil for manufacturing, or to sunflower and canola for edible vegetable oil. However, as noted below, there are remarkable dietary advantages to hempseed oil, which accordingly has good potential for penetrating the salad oil market, and for use in a very wide variety of food products. There is also good potential for hemp oil in cosmetics and skin-care products.
The safety and risks of using CBD for dogs have not yet been researched. The U.S. Food and Drug Administration has not approved CBD and has not issued a dosing chart. Therefore, we do not know what size dosage would be toxic. Any medication or supplement carries the risk of a reaction. It is always advisable, when giving your dog something new, to start out with small amounts and then closely monitor the effects. And always check with your veterinarian first.

Document It: Keep a journal of your dog before and for several days if you decide to use a CBD product. This will help you decide whether it’s having a positive effect. Better still, record video of your dog to document their progress, or lack thereof (this will help you overcome the flaws of human memory). Or ask your friends/family whether they’ve noticed any difference in your dog without telling them that you’ve been giving your dog CBD (the closest you’ll get to a blinded study). 
So-called “pure hybrids,” while oxymoronic in name, indicate marijuana strains that are believed to offer a perfect blend or balance of sativa’s energizing and indica’s sedating effects. Other hybrid strains of cannabis tend to place the emphasis on one end of the spectrum or the other. These are called “sativa-dominant” or “indica-dominant,” accordingly.

I was in a car accident several years ago I have tried everything to help relieve the pain in my back due to the accident nothing has worked! I picked this up thinking I would give it a shot and fell in love it worked wonders and everyone in my house now uses this from my diabetic son to my mother. Thank you for actually having a product that does what it says!! I feel like the old me now


In the last few decades, scientists also began looking into using CBD for dogs and cats, examining its health benefits and safety, and a lot more animal studies have emerged as a result (Iffland et al. 2017; Cannabis Cannabinoid Res). Today, we're seeing a lot of news relating to how dogs recover from many diseases, some of which are initially said to be fatal, thanks to the use of CBD products.
Furthermore, medical cannabis use is legal in many more places than recreational marijuana use. Current research, alongside patient and caregiver testimony, attests to the many medicinal applications of marijuana. From pain to serious neurological diseases, medical cannabis is emerging as a safe and viable alternative to many common prescription medications.

That's not to say CBD-infused creams definitely won't reduce your acute pain or muscle soreness. That's because pretty much all of these creams on the market right now have other scientifically-proven analgesic compounds, like menthol, camphor, and capsaicin which are also found in other, non-CBD topical pain relievers. "Any cream with a heating or cooling sensation desensitizes the nerves to pain by distracting them with stimuli on top," Dr. Colberg explains. Plus you're often massaging the area as you apply, which improves circulation and reduces muscle spasms, he adds.

By 1938, Popular Mechanics called hemp the “Billion Dollar Crop,”1 praising its potential to produce 25,000 different products, as high as $192 billion in today’s market and capable of producing four times the paper per acre than trees. Farmers from the Midwest to the East coast harvested more than 150,000 acres for the war’s Hemp for Victory Program, implemented by the USDA from 1942 through 1946, but rumblings by the competition had already started.

Edible cannabis, however, is quickly making up ground as a go-to method for consuming medical marijuana. Indeed, some states with legal medical marijuana laws still forbid smoking marijuana. Instead, medical forms of the drug are only available in pill or capsule form. Oils and tinctures, which are made from extracting cannabinoids from herbaceous material, are also commonly prescribed in the form of cannabis edibles.


In September 2005, New Scientist reported that researchers at the Canberra Institute of Technology had identified a new type of Cannabis based on analysis of mitochondrial and chloroplast DNA.[81] The New Scientist story, which was picked up by many news agencies and web sites, indicated that the research was to be published in the journal Forensic Science International.[82]
Over the ages, countless innovations have attempted to improve on the basic experience of inhaling the smoke of combusted cannabis. As a result, there are numerous ways to smoke marijuana. The rolling technique is at the root of joints, blunts, and spliffs. On the other hand, glassware and other devices are essential for smoking weed out of a pipe, bong, or bubbler.
