A limited number of studies have examined the effects of cannabis smoking on the respiratory system.[88] Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis.[68] The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease.[89] Short-term use of cannabis is associated with bronchodilation.[90] Other side effects of cannabis use include cannabinoid hyperemesis syndrome.[91]
Based on studies of sex reversal in hemp, it was first reported by K. Hirata in 1924 that an XY sex-determination system is present.[26] At the time, the XY system was the only known system of sex determination. The X:A system was first described in Drosophila spp in 1925.[29] Soon thereafter, Schaffner disputed Hirata's interpretation,[30] and published results from his own studies of sex reversal in hemp, concluding that an X:A system was in use and that furthermore sex was strongly influenced by environmental conditions.[27]
Our understanding of CBD cannabis oil has expanded and we’re more aware today than ever of the cannabinoid’s potential. Studies on CBD’s natural health benefits are extensive and groundbreaking research is being done regularly. We suggest you review the wide body of scientific research on CBD to get a better understanding of the cannabinoid’s health value. We answer the  “Will CBD get you high?” question here.
While very few clinical trials have explored the pain-relieving effects of CBD oil, a report published in the Cochrane Database of Systematic Reviews in 2018 examined the use of a variety of cannabis-based medicines and found they might be of some benefit in the treatment of chronic neuropathic pain. A type of pain triggered by damage to the somatosensory system (i.e., the system responsible for processing sensory stimuli), neuropathic pain often occurs in people with conditions like diabetes and multiple sclerosis.
CBD oil is extracted from the industrial hemp plant, Cannabis Sativa. The seeds of the hemp plant are pressed until the oils are released. This is what makes cannabidiol different from and less psychoactive than THC, which is extracted from the marijuana plant, Cannabis Indica. The industrial hemp oil has traces of THC in it, about 3% in potency, not sufficient in causing a ‘high’. Despite its non-addictive nature, CBD oil may require a medical prescription for legal acquisition in some provinces.

There are many ways to prepare cannabis for consumption. And while final marijuana products may come in many forms, each aims to provide rich concentrations of the terpenes, cannabinoids, and other desirable compounds the marijuana plant produces. From the simple process of drying and curing marijuana flowers, to the sophisticated chemistry of producing cannabis concentrates, here’s a guide to the most common forms of cannabis.
The legal problems occur once the extracts contain higher percentages of THC, or when they’re made from cannabis plants that are no longer considered “hemp” (so basically high THC plants). Products with these extracts might be in violation of the United States Controlled Substances Act (US CSA). This is when laws regarding specific states or countries will apply.

Since the demand for CBD has increased, so has the number of overseas companies who are selling CBD products. The problem is, many of their products have been found to contain chemicals, heavy metals, and toxins. The companies in China and Eastern Europe, in particular, have been selling low-quality CBD items that could potentially do you more harm than good.
Cannabis for industrial uses is valuable in tens of thousands of commercial products, especially as fibre[107] ranging from paper, cordage, construction material and textiles in general, to clothing. Hemp is stronger and longer-lasting than cotton. It also is a useful source of foodstuffs (hemp milk, hemp seed, hemp oil) and biofuels. Hemp has been used by many civilizations, from China to Europe (and later North America) during the last 12,000 years.[107][108] In modern times novel applications and improvements have been explored with modest commercial success.[109][110]

Hashish (also spelled hasheesh, hashisha, or simply hash) is a concentrated resin cake or ball produced from pressed kief, the detached trichomes and fine material that falls off cannabis flowers and leaves.[178] or from scraping the resin from the surface of the plants and rolling it into balls. It varies in color from black to golden brown depending upon purity and variety of cultivar it was obtained from.[179] It can be consumed orally or smoked, and is also vaporised, or 'vaped'.[180] The term "rosin hash" refers to a high quality solventless product obtained through heat and pressure.[181]
Many a time, multiple cannabinoid compounds are used together, either knowingly or unknowingly.  It is, hence, tough to discern the extent to which each compound is involved in causing the desired effect. There are cases where a group of cannabinoids works synergistically in bringing about bodily reactions. Studies selectively employing CBD oil are few in number, but promising.
The nutrition and supplement industry—which includes CBD products—is almost wholly unregulated. “The concentrations in products are only approximate, and I don’t know how well they’re tracked,” Szaflarski says. Even if you could absolutely trust a product’s label—and many CBD manufacturers, aware of the current scrutiny on their industry, go to great lengths to assure consumers of the quality of their products—there aren’t a lot of concrete facts when it comes to the type or amount of CBD a person should take for a specific ailment or aim.

A. The Agriculture Improvement Act of 2018 changes certain federal authorities relating to the production and marketing of hemp, defined as cannabis (Cannabis sativa L.), and derivatives of cannabis with extremely low (less than 0.3 percent on a dry weight basis) concentrations of the psychoactive compound delta-9-tetrahydrocannabinol (THC). These changes include removing hemp from the Controlled Substances Act, which means that it will no longer be an illegal substance under federal law. However, Congress explicitly preserved the agency's current authority to regulate products containing cannabis or cannabis-derived compounds under the FD&C Act and section 351 of the Public Health Service Act. Please see the FDA’s statement on the signing of the Agriculture Improvement Act of 2018. 

According to the United States Department of Health and Human Services, there were 455,000 emergency room visits associated with cannabis use in 2011. These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use. The drug use must be "implicated" in the emergency department visit, but does not need to be the direct cause of the visit. Most of the illicit drug emergency room visits involved multiple drugs.[75] In 129,000 cases, cannabis was the only implicated drug.[76][77]
Cannabidiol can be taken into the body in multiple different ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as CBD oil containing only CBD as the active ingredient (no added tetrahydrocannabinol [THC] or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution.[2] CBD does not have the same psychoactivity as THC,[9][10][11] and may affect the actions of THC.[7][8][9][12] Although in vitro studies indicate CBD may interact with different biological targets, including cannabinoid receptors and other neurotransmitter receptors,[9][13]as of 2018 the mechanism of action for its biological effects has not been determined.[8][9]
After a month of researching legalities of CBD industry here in Colorado, I must say I’m still confused. I went to city authorities and at one point was told I needed a $50,000 permit, ya no! So went to the state level with Dept of Ag, my intent was to make cbd infused dog treats with proper dosage. NOPE can’t do that it’s illegal, so I said I’m going to keep calling until you say yes to something. Decided I would make cbd infused creams etc. I was told yes it was legal but don’t ship across state lines. Hmmm ok. Do you have to be 21 to purchase? No! Well needless to say I made product, set up website and carried on, I’m two weeks into it and SQuare credit card has cut me off! I’m am totally confused as to what I can and can’t do as I tried to follow all the laws etc. I would so appreciate any input you have on this!

Via CB1 receptor activation, THC indirectly increases dopamine release and produces psychotropic effects.[145] Cannabidiol (CBD) also acts as an allosteric modulator of the μ- and δ-opioid receptors.[146] THC also potentiates the effects of the glycine receptors.[147] It is unknown if or how these actions contribute to the effects of cannabis.[148]

Final thoughts: Hemp oil and hemp derived CBD oil is legal in all fifty states, but there certainly is a stigma to it. Because of that it can be very hard to find reliable information to educate yourself with. This is a great dietary supplement and may help decrease inflammation, improve skin, help with mild pain, etc. If you have severe pain, hemp derived CBD oil may be what you need.
NIDA provides research-grade marijuana for scientific study. The agency is responsible for overseeing the cultivation of marijuana for medical research and has contracted with the University of Mississippi to grow marijuana for research at a secure facility. Marijuana of varying potencies and compositions is available. DEA also may allow additional growers to register with the DEA to produce and distribute marijuana for research purposes.

While there are more unknowns than knowns at this point, Grant says he doesn’t discount all the anecdotal CBD reports. “You hear somebody say, ‘Hey, I gave this to myself and my kid and we feel a lot better,’ and we should never dismiss that kind of information,” he says. He points out that many modern medicines were discovered when researchers followed up on exactly this sort of human trial-and-error evidence. “But we still need to do the studies that confirm whether all the good things are true, and how much to give, and how to give it,” he says. “These are all questions that need to be answered.”


Ringo’s Gift: This cultivar is named after the cannabidiol pioneer, Lawrence Ringo. Ringo’s Gift is a cross between two other CBD-rich strains, AC/DC and Harle-tsu. Its CBD to THC ratio varies from 1:1 to 22:1, but it consistently favors CBD. Ringo’s Gift smells of earthy pine and promises full-bodied relaxation in tandem with calming cerebral effects which, together, silence pain and anxiety.
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]

Overall, researchers agree that while there isn’t conclusive data to support CBD oil as the preferred method of pain management, these types of products have a lot of potential. CBD products might be able to offer relief for many people who have chronic pain, all without causing intoxication and dependence. Oil versions of CBD may not be as effective as other forms, and more human studies are needed.


Many monoecious varieties have also been described,[20] in which individual plants bear both male and female flowers.[21] (Although monoecious plants are often referred to as "hermaphrodites", true hermaphrodites – which are less common in Cannabis – bear staminate and pistillate structures together on individual flowers, whereas monoecious plants bear male and female flowers at different locations on the same plant.) Subdioecy (the occurrence of monoecious individuals and dioecious individuals within the same population) is widespread.[22][23][24] Many populations have been described as sexually labile.[25][26][27]
CBD is not addictive. ‘An addiction to marijuana can develop as a severe form of "marijuana use disorder" which affects an estimated 30 per cent of marijuana users,' says Dr Brewer. 'This develops from a dependence on the psychoactive ingredient, THC, which is found in marijuana strains of cannabis, and which can cause a high and withdrawal symptoms.’
This does nothing for me. I have been taking between 4 and 8 Aleeve a day for back pain related to kyphosis and hoped this would help me cut down on those medications. This is hemp oil, not CBD oil. After trying this and receiving no results I switched to CBD oil from a well reviewed company and the CBD oil is helping. I now take the CBD oil twice a day and have noticeable results. I have cut my regular pain meds to one or two a day.
The mosaic of laws that govern CBD legality across the globe varies just as much as the legislation across the US. Generally, CBD extract is legal in most countries, but what makes it illegal is where and what it’s extracted from. Most Group of 20 (G20) countries allow CBD extracted from industrial hemp, but not CBD extracted from whole-plant marijuana. Note, however, the differences between the two. Legislation regarding international travel with CBD also varies among countries. For the foreseeable future, the best practice would be to search online, or contact the respective embassies or consulates, before traveling to determine whether your CBD is safe and legal.

On October 17, 2018, Canada legalized cannabis for recreational adult use[54] making it the second country in the world to do so after Uruguay and the first G7 nation.[55] The Canadian Licensed Producer system may become the Gold Standard in the world for safe and secure cannabis production,[56] including provisions for a robust craft cannabis industry where many expect opportunities for experimenting with different strains.[57] Laws around use vary from province to province including age limits, retail structure, and growing at home.[54]

Working with farms in Northern Europe, we carefully tested and reviewed 3,000 cultivars to find the one that would thrive and produce the optimal ratio of cannabinoids necessary for our products. The oil sourced from these plants are high in CBD and low in THC, the cannabinoid that gets users high, making our extracted hemp oil products legal to purchase in the U.S.
The Haleigh's Hope Act was signed by Georgia's Governor in 2016. This law has made the use of cannabis oil legal, however, it cannot contain any more than 5% THC. It can also only be used for medical reasons. CBD products from Every Day Optimal contain 0% THC and their items can only be used for medical purposes. The state believes that CBD can have an amazing impact on the lives of people all across the U.S. who are suffering from debilitating health problems.

In April of 2015 Gov. Fallin signed HB 2154 which allows physicians in Oklahoma to recommend a high-CBD cannabis oil (less than .3% THC) to minors suffering from a severe epilepsy disorder like Lennox-Gastaut Syndrome or Dravet Syndrome. In 2016, the state adopted HB 2835, which expanded legal protections to patients of all ages and added several new qualifying conditions.

While CBD oil does a fine job of reducing stress, anxiety and the effects of chronic pain, it doesn’t have the same localized effect as CBD cream for pain. For example, if you have severe shoulder pain, CBD cream is a much better option than oil because it will get to work on that area immediately. The CBD in the topical combines with the CB2 receptors in our skin. As it doesn’t reach the bloodstream, it is best used for localized pain since it doesn’t offer full-body pain relief.
