There is concern that cannabis may contribute to cardiovascular disease,[102] but as of 2018, evidence of this relationship was unclear.[103][104] Cannabis is believed to be an aggravating factor in rare cases of arteritis, a serious condition that in some cases leads to amputation. Because 97% of case-reports also smoked tobacco, a formal association with cannabis could not be made. If cannabis arteritis turns out to be a distinct clinical entity, it might be the consequence of vasoconstrictor activity observed from delta-8-THC and delta-9-THC.[105] Other serious cardiovascular events including myocardial infarction, stroke,[106] sudden cardiac death, and cardiomyopathy have been reported to be temporally associated with cannabis use. Research in these events is complicated because cannabis is often used in conjunction with tobacco, and drugs such as alcohol and cocaine.[107] These putative effects can be taken in context of a wide range of cardiovascular phenomena regulated by the endocannabinoid system and an overall role of cannabis in causing decreased peripheral resistance and increased cardiac output, which potentially could pose a threat to those with cardiovascular disease.[108] There is some evidence from case reports that cannabis use may provoke fatal cardiovascular events in young people who have not been diagnosed with cardiovascular disease.[109] Smoking cannabis has also been shown to increase the risk of myocardial infarction by 4.8 times for the 60 minutes after consumption.[110]
Results of a Phase III study (N = 177) comparing Sativex, THC-predominant extract and placebo in intractable pain due to cancer unresponsive to opiates (Johnson and Potts 2005) demonstrated that Sativex produced highly statistically significant improvements in analgesia (Table 1), while the THC-predominant extract failed to produce statistical demarcation from placebo, suggesting the presence of CBD in the Sativex preparation was crucial to attain significant pain relief.

Been using product for a few days now ,I'm about one my 6th dose. I noticed today my hand from nerve damage has not dropped anything or felt numb,or even trembled. Even axienty has been managable. However I'm taking 250mgs.I boosted it up to 500mgs.3 or 4 times daily ,of 250mgs. It seems to have best effect atleast today.It's cold and rainy which,is better than snow ,is my most hightened pain days.Today 4/24/18. Has been a God send! 1 pain and axienty day free ...Makes me a believer! I stand by this products effectiveness. Hope my review helps another soul,that lives with same aliments.

Users of CBD have found that CBD products help them with a wide range of health problems such as insomnia, physical pain, and anxiety. CBD has also been studied for its anti-seizure properties and its ability to combat brain damage caused by opioid addiction. Currently, the Food and Drug Administration (FDA) is in the process of approving a CBD-based epilepsy medication which will make it the first cannabis-derived prescription medication in the United States.
Very few randomized controlled trials (RCTs) have been conducted using smoked cannabis (Campbell et al 2001) despite many anecdotal claims (Grinspoon and Bakalar 1997). One such study documented slight weight gain in HIV/AIDS subjects with no significant immunological sequelae (Abrams et al 2003). A recent brief trial of smoked cannabis (3.56% THC cigarettes 3 times daily) in HIV-associated neuropathy showed positive results on daily pain, hyperalgesia and 30% pain reduction (vs 15% in placebo) in 50 subjects over a treatment course of only 5 days (Abrams et al 2007) (Table 1). This short clinical trial also demonstrated prominent adverse events associated with intoxication. In Canada, 21 subjects with chronic pain sequentially smoked single inhalations of 25 mg of cannabis (0, 2.5, 6.0, 9.5% THC) via a pipe three times a day for 5 days to assess effects on pain (Ware et al 2007) with results the authors termed “modest”: no changes were observed in acute neuropathic pain scores, and a very low number of subjects noted 30% pain relief at the end of the study (Table 1). Even after political and legal considerations, it remains extremely unlikely that crude cannabis could ever be approved by the FDA as a prescription medicine as outlined in the FDA Botanical Guidance document (Food and Drug Administration 2004; Russo 2006b), due to a lack of rigorous standardization of the drug, an absence of Phase III clinical trials, and pulmonary sequelae (bronchial irritation and cough) associated with smoking (Tashkin 2005). Although cannabis vaporizers reduce potentially carcinogenic polyaromatic hydrocarbons, they have not been totally eliminated by this technology (Gieringer et al 2004; Hazekamp et al 2006).
Szaflarski explains that cannabis contains about 500 different compounds, some of which—including CBD and THC—interact with certain chemical receptors in the human nervous system. But unlike THC, CBD isn’t psychoactive—meaning it doesn’t cause any kind of a high. Despite that, the US Drug Enforcement Agency classifies CBD (and other cannabis compounds) as schedule I substances, making their sale illegal in many states. 

Despite the many states that have legalized some or all forms of marijuana, federally the U.S. Drug Enforcement Administration (DEA) continues to classify CBD as a Schedule I drug. Schedule I drugs are defined by the DEA as "drugs with no currently accepted medical use and a high potential for abuse." This is how not just CBD, but the entire cannabis plant is classified.
Topicals represent a newer emerging market in medical marijuana products geared toward health and beauty. Cannabinoids can be absorbed through the skin for certain therapeutic benefits without any psychoactivity. Additionally, the essential oils in hemp and cannabis provide many benefits for skin health. From moisturizers to shampoos and deodorants, medical cannabis products continue to diversify.
I’ve been wanting to know on how to understand the life cycle of a marijuana plant but I don’t know how to get started. I do research on my own, I also read lots of articles but this one caught my attention https://www.bonzaseeds.com/blog/life-cycle-marijuana-plant/ It has the content of all you about to know in planting and to understand the life cycle of marijuana plant.

A 2015 review found that the use of high CBD-to-THC strains of cannabis showed significantly fewer positive symptoms such as delusions and hallucinations, better cognitive function and both lower risk for developing psychosis, as well as a later age of onset of the illness, compared to cannabis with low CBD-to-THC ratios.[278] A 2014 Cochrane review found that research was insufficient to determine the safety and efficacy to using cannabis to treat schizophrenia or psychosis.[279] As of 2017, the molecular mechanisms for the anti-inflammatory and possible pain relieving effects of cannabis are under preliminary research.[280]
Choosing CBD products isn’t as simple as picking something off the dispensary shelf and then walking out the door. 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. Some CBD products are completely devoid of cannabinoids including CBD, despite package labeling. The FDA purchased a number of CBD products online in 2015 and 2016 to test them for the presence of CBD and other cannabinoids. They found that the amount of CBD these products claimed on their labels was markedly inaccurate; some didn’t even contain CBD.
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.[120] 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.[121] Few high quality studies have been performed on the long-term effects of cannabis on cognition, and results were generally inconsistent.[122] Furthermore, effect sizes of significant findings were generally small.[121] One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions.[123] 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.[124] 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.[116] Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency.[125]
In fact, CBD is therapeutic in nature, and will work to manipulate bodily systems at the cellular level to return afflicted organ systems, tissue systems, and even chemical systems in the central nervous system back to a state of health and homeostasis. This is precisely why it has been capable of treating conditions such as depression and anxiety, to chronic physical ailments such as pain, inflammation, arthritis, and more.
Had bilateral total knee replacements a year ago and been in pain since. Found out have 2 staph infections in one knee and a problem with tendon in the other. I will be going through 3 morw surgeries to correct these problems. This product has been a Godsend to me!! If it wasn’t for it, I could not walk the length of Walmart without being in pain. I will NEVER go without having this cream on hand, because I know how much relief it has given me. Even if my knees ever get fixed correctly, I will keep this on hand for any other pains I may get.
Chronic pain represents an emerging public health issue of massive proportions, particularly in view of aging populations in industrialized nations. Associated facts and figures are daunting: In Europe, chronic musculoskeletal pain of a disabling nature affects over one in four elderly people (Frondini et al 2007), while figures from Australia note that older half of older people suffer persistent pain, and up to 80% in nursing home populations (Gibson 2007). Responses to an ABC News poll in the USA indicated that 19% of adults (38 million) have chronic pain, and 6% (or 12 million) have utilized cannabis in attempts to treat it (ABC News et al 2005).

     CBD content in Hemp oil, when extracted from the proper strains, can be very high as Hemp plants are now the very strains that are being used to breed high CBD levels back into Cannabis after years of selective recreational breeding for high THC values. Well known strains such Charlotte's Web are hybrids that were selected from crosses with High CBD Hemp varietals and those Hemp genetics are what account for the new High CBD Strains of Marijuana and commercial Hemp that have and are being developed.


Everything you need to know about marijuana (cannabis) Marijuana, or cannabis, is the most commonly used illicit drug in the world. It alters the mood and affects nearly every organ in the body. With at least 120 active compounds, marijuana may have health benefits as well as risks. We describe these, addiction, and withdrawal. Learn more about cannabis here. Read now
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.

Illinois and Chicago permit the retail sale of CBD products, as long as they are derived from hemp, another plant in the cannabis family, and have less than 0.3 percent of the psychoactive cannabis compound THC. If a firm discloses in its business license that it is selling CBD products, the city is making note of it in case additional regulations are adopted, Lilia Chacon, spokeswoman for the Department of Business Affairs and Consumer Protection, said in an email.


In June 2018, the FDA approved the drug Epidiolex, an oral preparation of pure CBD for treatment of two rare and severe forms of epilepsy in children. The drug is made by the GW Pharmaceutical Company and was tested in three randomized, double-blind, placebo-controlled clinical trials, including 516 patients. It was found to be effective in reducing the frequency of seizures. 

There are also other difficulties in researching the effects of cannabis. Many people who smoke cannabis also smoke tobacco.[276] This causes confounding factors, where questions arise as to whether the tobacco, the cannabis, or both that have caused a cancer. Another difficulty researchers have is in recruiting people who smoke cannabis into studies. Because cannabis is an illegal drug in many countries, people may be reluctant to take part in research, and if they do agree to take part, they may not say how much cannabis they actually smoke.[277]
Endocannabinoids are organically produced by the human body, generated by the endocannabinoid system. Endocannabinoids have been found to help in the regulation of sleep, pain and the responses of the immune system. Cannabis scientists have been investigating the role of physiological cannabinoids in tissue recovery and disease. It is fascinating that the endocannabinoids activate the same receptors as the psychoactive THC.
RSHO™ CBD hemp oil is available in four varieties of high-quality, pure cannabidiol oil, including Green Label, Blue Label, Gold Label, and Special Blend. RSHO™ contains between 50mg and 190mg of cannabidiol per 0.5 gram serving. Each of the pure CBD hemp oil varieties come in 3 gram and 10 gram applicators. For regular users, 3 packs and 6 packs of applicators are available.
Finally, compare the levels of CBD in milligrams (mg) in each product to assess value for money. ‘Quality packaging will tell you the total amount of CBD supplied within the pack, as well as the amount per dose (be it a capsule, gummy, oil dropper or spray) in milligrams, Dr Brewer explains. ‘Products with this labelling allow you to see exactly how much CBD you’re buying and taking.’
Because it takes a significantly larger amount of hemp stalks to produce hemp oil, there is an increased risk of contamination of toxins contained within the plant. This is a result of hemp's strong bio-accumulator properties, where it pulls toxins from the soil it grows in. Many hemp oils are also known to lack the full spectrum of terpenes and other cannabinoids that are believed to act synergistically with the CBD, meaning that consumers receive less of a benefit. That being said, there are some brands that test rigorously to make sure that the CBD content, as well as the terpenes and other cannabinoids, are up to par. It's a good sign if they offer to provide a certificate of analysis, which will tell you what kind of compounds are in the hemp oil and in what concentrations

As we continue to work with CBD our knowledge of the power of this plant is growing as well. We are obtaining much better results as we work with our patients to think themselves out of pain. You might think I’m kidding, but I’m not. Chronic pain changes the brain and lays down dysfunctional pathways. CBD promotes neuroplasticity and neurogenesis – the formation of new brain cells that develop into new pathways of thinking. We are encouraged and excited to continue to work with CBD to maximize its potential to address chronic pain.
When muscles relax, movement becomes much easier. This is especially important for people with chronic pain who still want to exercise or do things like yoga, which can be painful initially, but improves mobility and builds muscle. For anybody weary of the pain that comes from too much exertion, try using CBD before and after a workout, and spend enough time warming up. If you have a condition such as ankylosing spondylitis, CBD will slow down arthritic progression, enabling you to move more freely.

The clinical trials performed with Sativex have recently been assessed in two independent review articles (Barnes 2006; Pérez 2006). In a Phase II clinical trial in 20 patients with neurogenic symptoms (Wade et al 2003), Tetranabinex, Nabidiolex, and Sativex were tested in a double-blind RCT vs placebo (Table 1). Significant improvement was seen with both Tetranabinex and Sativex on pain (especially neuropathic), but post-hoc analysis showed symptom control was best with Sativex (p < 0.0001), with less intoxication than with THC-predominant extract.
In 1925, a compromise was made at an international conference in The Hague about the International Opium Convention that banned exportation of "Indian hemp" to countries that had prohibited its use, and requiring importing countries to issue certificates approving the importation and stating that the shipment was required "exclusively for medical or scientific purposes". It also required parties to "exercise an effective control of such a nature as to prevent the illicit international traffic in Indian hemp and especially in the resin".[210][211] In the United States in 1937, the Marihuana Tax Act was passed,[212] and prohibited the production of hemp in addition to cannabis.

Although global abnormalities in white matter and grey matter are not associated with cannabis abuse, reduced hippocampal volume is consistently found. Amygdalar abnormalities are sometimes reported, although findings are inconsistent.[111][112][113] Preliminary evidence suggests that this effect is largely mediated by THC, and that CBD may even have a protective effect.[114]
Chronic pain can be a very devastating diagnosis. For those of us without this condition, it’s hard to imagine what someone with chronic pain is going through. Chronic pain is usually secondary to some form of trauma, making a bad situation far worse. Imagine the worst pain you have every experienced and then try to imagine having that pain day in and day out for months or worse, for years.
An alternative to the gateway hypothesis is the common liability to addiction (CLA) theory. It states that some individuals are, for various reasons, willing to try multiple recreational substances. The "gateway" drugs are merely those that are (usually) available at an earlier age than the harder drugs. Researchers have noted in an extensive review that it is dangerous to present the sequence of events described in gateway "theory" in causative terms as this hinders both research and intervention.[270]
Over the past few decades, most strains have been bred to increase the amount of the main psychoactive component, (-)-trans-delta9-tetrahydrocannabinol (THC). However, within the past decade, researchers have become increasingly interested in the medical benefits of another compound found in both plants, known as cannabidiol (CBD). CBD is a non-psychoactive component of the cannabis plant but is reputed to help with a myriad of medical conditions.

Whether the drug and non-drug, cultivated and wild types of Cannabis constitute a single, highly variable species, or the genus is polytypic with more than one species, has been a subject of debate for well over two centuries. This is a contentious issue because there is no universally accepted definition of a species.[54] One widely applied criterion for species recognition is that species are "groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups."[55] Populations that are physiologically capable of interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes considered to be separate species.[55] Physiological barriers to reproduction are not known to occur within Cannabis, and plants from widely divergent sources are interfertile.[43] However, physical barriers to gene exchange (such as the Himalayan mountain range) might have enabled Cannabis gene pools to diverge before the onset of human intervention, resulting in speciation.[56] It remains controversial whether sufficient morphological and genetic divergence occurs within the genus as a result of geographical or ecological isolation to justify recognition of more than one species.[57][58][59]
