THC and its major (inactive) metabolite, THC-COOH, can be measured in blood, urine, hair, oral fluid or sweat using chromatographic techniques as part of a drug use testing program or a forensic investigation of a traffic or other criminal offense. The concentrations obtained from such analyses can often be helpful in distinguishing active use from passive exposure, elapsed time since use, and extent or duration of use. These tests cannot, however, distinguish authorized cannabis smoking for medical purposes from unauthorized recreational smoking. Commercial cannabinoid immunoassays, often employed as the initial screening method when testing physiological specimens for marijuana presence, have different degrees of cross-reactivity with THC and its metabolites. Urine contains predominantly THC-COOH, while hair, oral fluid and sweat contain primarily THC. Blood may contain both substances, with the relative amounts dependent on the recency and extent of usage.
Hemp extract is taken from the whole plant and contains higher levels of CBD than hemp seed oil. This is where the CBD levels come from. However, we are confused by the labeling. If we expect the 500 product to have 500 mg of CBD, are we right? The label shows 500 mg of ‘phytocannabinoid hemp oil’. The solution is that about 160% of that is CBD, with the other cannabinoids as a tag along. This is effective.
In Canada, the methodology used for analyses and sample collection for THC analysis of hemp plantings is standardized (at the Health Canada/Therapeutics Program/Hemp web site at www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/hemp.html, see “Industrial Hemp Technical Manual” for procedures on sampling plant materials and chemical procedures for determining THC levels). The regulations require that one of the dozen independent laboratories licensed for the purpose conduct the analyses and report the results to Health Canada. Sample collection is also normally carried out by an independent authorized firm. The Canadian system of monitoring THC content has rigidly limited hemp cultivation to cultivars that consistently develop THC levels below 0.3%.
Subcritical CO2 extraction technology allows us to extract all of the nutrients, without using any heat or harmful solvents. The result is a high potency, whole food CBD Oil with exceptional nutritional qualities. Hempworx CBD oil contains all the CBD’s and 400+ other nutrients that work synergistically in an easy-to-use, easy-to-absorb form. Most CBD companies use solvents to perform extraction potentially destroying the potential therapeutic benefit of the whole cannabis phytocomplex. There are more than 400 phytonutrients in hemp.
Not true. A family member of mine also failed a drug test using Hempworx that was supposedly zero THC. They contacted their rep who refused to respond to calls or texts. So then they went straight to the company who said they were sorry but nothing they could do because supposedly their lab is different than the one that did the drug test??? What a scam.
In some areas where cannabis use had been historically tolerated, new restrictions were instituted, such as the closing of cannabis coffee shops near the borders of the Netherlands, and closing of coffee shops near secondary schools in the Netherlands. In Copenhagen, Denmark in 2014, mayor Frank Jensen discussed possibilities for the city to legalize cannabis production and commerce.
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. A 2014 Cochrane review found that research was insufficient to determine the safety and efficacy to using cannabis to treat schizophrenia or psychosis. As of 2017, the molecular mechanisms for the anti-inflammatory and possible pain relieving effects of cannabis are under preliminary research.
The Gateway Hypothesis states that cannabis use increases the probability of trying "harder" drugs. The hypothesis has been hotly debated as it is regarded by some as the primary rationale for the United States prohibition on cannabis use. A Pew Research Center poll found that political opposition to marijuana use was significantly associated with concerns about health effects and whether legalization would increase marijuana use by children.
Fibres are obtained by subjecting the stalks to a series of operations—including retting, drying, and crushing—and a shaking process that completes separation from the woody portion, releasing the long, fairly straight fibre, or line. The fibre strands, usually over 1.8 metres (5.8 feet) long, are made of individual cylindrical cells with an irregular surface. The fibre, longer and less flexible than flax, is usually yellowish, greenish, or a dark brown or gray and, because it is not easily bleached to sufficiently light shades, is rarely dyed. It is strong and durable and is used for cordage—e.g., twine, yarn, rope, cable, and string—and for artificial sponges and such coarse fabrics as sacking (burlap) and canvas. In Italy some hemp receives special processing, producing whitish colour and attractive lustre, and is used to make fabric similar to linen.
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”
For a fiber crop, hemp is cut in the early flowering stage or while pollen is being shed, well before seeds are set. Tall European cultivars (greater than 2 m) have mostly been grown in Canada to date, and most of these are photoperiodically adapted to mature late in the season (often too late). Small crops have been harvested with sickle-bar mowers and hay swathers, but plugging of equipment is a constant problem. Hemp fibers tend to wrap around combine belts, bearings, indeed any moving part, and have resulted in large costs of combine repairs (estimated at $10.00/ha). Slower operation of conventional combines has been recommended (0.6–2 ha/hour). Large crops may require European specialized equipment, but experience in North America with crops grown mainly for fiber is limited. The Dutch company HempFlax has developed or adapted several kinds of specialized harvesting equipment (Fig. 44, 45).

Right, the collection of the Vavilov Institute, St. Petersburg; of the 278 accessions for which chemical analyses were reported in Anonymous (1975), about 55% had THC levels >0.3%.
Another notable study conducted by Mechoulam was done on mice bred to have a version of type-1 diabetes. The diabetes was designed to manifest right around 14 weeks, so the mice were treated with CBD for the first 7 weeks of their life and then again in another 7 weeks. He concluded that only 30% had developed diabetes compared to the 90-100% given the placebo.
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.
HempWorx did not come into the picture until May 2017, when it merged into My Daily Choice and became its flagship product, supplementing the line of “nutritional sprays” promoted for everything from weight loss (Trim 365) to cognitive function (simply, Brain). The idea for HempWorx came in the waiting room of a doctor’s office. “I was really sick,” Josh’s wife, Jenna Zwagil, said in a recent interview in which she recounted the visit. As the story goes, in 2014, she was diagnosed with celiac disease. She cut gluten out of her diet but wasn’t getting better. As she waited to be called in for her appointment, she started reading an article on her phone on “the power of cannabis” in treating autoimmune disorders like hers. When she finished the article, she said, she walked out of the office without seeing the doctor to immediately seek out cannabidiol or CBD. Josh and Jenna Zwagil’s “How We Met” story, posted on a shared Facebook account, picks it up from there:
I find it hilarious that there are trolls, even on product review pages. Anywho, I tried a bottle of their oil as a customer and not as an affiliate. I was suffering with a pretty rare condition and also had a severe iron deficiency. Both conditions resolved (I had had iron infusions months earlier that was taking its sweet time to make a difference with my symptoms), maybe a couple of months later. I also stoopped getting respiratory infections. I was able to get a lot more rest than I had been getting- eventually, the symptoms of my other conditions started disappearing. I have minimal symptoms now and I am working on keeping my diet nutrient-rich. I feel much better than I did before I started the oil. I haven’t used it again for financial reasons (I’m a sad cheapskate) but if I came into some money, I might buy another bottle.
