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).

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.
Research suggests that CBD may exert some of its pharmacological action through its inhibition of fatty acid amide hydrolase (FAAH), which may in turn increase the levels of endocannabinoids, such as anandamide, produced by the body.[6] It has also been speculated that some of the metabolites of CBD have pharmacological effects that contribute to the biological activity of CBD.[39]
A. The FDA is aware that there are potential adverse health effects with use of marijuana in pregnant or lactating women. Published scientific literature reports potential adverse effects of marijuana use in pregnant women, including fetal growth restriction, low birth weight, preterm birth, small-for-gestational age, neonatal intensive care unit (NICU) admission, and stillbirth. [1, 2, 3] Based on published animal research, there are also concerns that use of marijuana during pregnancy may negatively impact fetal brain development.  [4, 5, 6 ] The American College of Obstetricians and Gynecologists (ACOG) recommends that women who are pregnant or contemplating pregnancy should be encouraged to discontinue marijuana use. In addition, ACOG notes that there are insufficient data to evaluate the effects of marijuana use on breastfed infants; therefore, marijuana use is discouraged when breastfeeding. [7] Pregnant and lactating women should talk with a health care provider about the potential adverse health effects of marijuana use.
I think being safe to eat is a moot point. These are topical products. I don’t think anybody is buying to eat them. It’s just a marketing tactic. In regards to the chapsticks, unless you were trying to literally eat the chapstick I think whatever negligible amount may make it past your lips and into your mouth, would certainly not be a health concern from any of these products. What concerns me more is there is zero efficacy with all of these products. Do they just decide over breakfast how much CBD needs to be added for the dosage to work? It’s ridiculous that they are marketing it as safe to eat, and people are buying into that bs and providing no clinical studies or research at all. Just my 2 cents
I purchased the 500 mg tincture to start. I make CBD but I use a different process that does not extract like the CO2 method The CO2 method is the best and you have to be careful when choosing CBD. Make sure that its organic NO GMO and grown in the USA I love how clear it is although it does have a little bit of cloudiness but this is normal. I have been using CBD to relieve anxiety I am agoraphobic and part of that is severe panic attacks. With my first 1 ML dose as soon as it came in the mail today I was starting to relax. I am only guessing but I will probably be taking 1 ML twice per day since this is the 500mg bottle once when I get up and once before bed so this bottle will not last me a month. If it works as well as expected especially after the first dose this morning then I will probably move up to the 1000 mg which will last me the month. One other thing you may have already read this information but this CBD has 0 THC. Thats important for those who work in professions that can not risk having high THC levels no pun intended.What makes me so confident in this product is how fast it worked. 1 ML under the tongue is the best way in my opinion to get the CBD oil to act quickly. This product gets great reviews for pain as well. Fortunately I dont suffer pain just anxiety and panic attacks. Thank you Medterra PS. I was not paid for this review LOL. I paid full price for this product and happy to do it.If Im able I will update this review if needed when I finish this bottle. Or leave another when I get the 1000 mg.
In 2015, The Hebrew University of Israel published a study that documented the potency of single-molecule CBD extract versus the potency of whole-plant CBD-rich extract. It found that extract taken from whole plant CBD-rich cannabis is therapeutically superior to single-molecule extract. The scientists behind this study noticed that science had been utilizing pure, single-molecule CBD, which resulted in a bell-shaped dose-response curve. This means that CBD’s efficacy plummets at very high and very low doses.

You are likely very familiar with the dangers that prescription painkillers (and other pharmaceuticals) present. In fact, it’s estimated that the majority of CBD oil users attempt to switch to the all-natural therapy for the precise reason of kicking prescription med habits, which all too often cause an overwhelming array of irritability, sleep disruption, digestive complications, and even thoughts of suicide.
I wanted to tell people here that CBD has been very effective for my anxiety, and helps with insomnia. For me, it was a cumulative effect, after a week of one dropper of oil, I can sleep very well at night. I feel like I am not polluting my body with commercial pharmaceuticals. I wish everyone here the best, and hope it works for you as well as it has for me.
“The brain has these receptors that respond to endocannabinoids, which are neurotransmitters that are naturally produced in the body and brain,” says Jerald Simmons, a neurologist at Houston’s Comprehensive Sleep Medicine Associates. “Some of the cannabinoids in the marijuana plant are very similar to the endocannabinoids in the brain, and they act on the same receptors.”
Hemp oil or hempseed oil is obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavour. The darker the color, the grassier the flavour. It should not be confused with hash oil, a tetrahydrocannabinol-containing oil made from the Cannabis flower, hailed by some[1] for its medicinal qualities.[2]
