At a time when great concern is accruing in relation to NSAIDs in relation to COX-1 inhibition and COX-2 inhibition , CBD, like THC, inhibits neither enzyme at pharmacologically relevant doses . A new explanation of inflammatory and analgesic effects of CBD has recently come to light with the discovery that it is able to promote signaling of the adenosine receptor A2A by inhibiting the adenosine transporter . Physicians are seeking new approaches to treatment of these conditions but many remain concerned about increasing governmental scrutiny of their prescribing practices , prescription drug abuse or diversion. Reveals the concentration of active cannabinoids for accurate dosage and to ensure the quality of the product. All products are quality tested by an independent third-party lab to ensure you get the best product possible, and the potency results are made public for your review.

- However, they take some time to apply and can be a little messy.
- There are cases where you might want to puncture a capsule for use on the skin, but for the most part, this is an orally administered product.
- One downside of capsules is that they take longer to feel the effects.
- But this is easily avoidable by taking the capsule with food.
- This may not be a concern for you if you use these kinds of products regularly.
Sativex has effect onset in 15–40 minutes, peaking in a few hours, quite a bit slower than drugs of high abuse potential. It has been claimed that inclusion of CBD diminishes psychoactive effects of THC, and may lower potential drug abuse liability of the preparation (see Russo ) for discussion). Prior studies from Sativex clinical trials do not support the presence reinforcement or euphoria as problems in administration . Thus, it is now longer tenable to claim that psychoactive effects are a necessary prerequisite to symptom relief in the therapeutic setting with a standardized intermediate onset cannabis-based preparation. Intoxication has remained a persistent issue in Marinol usage , in contrast.
Nabilone , is a synthetic dimethylheptyl analogue of THC that displays greater potency and prolonged half-life. It was also primarily developed as an anti-emetic in chemotherapy, and was recently re-approved for this indication in the USA. Prior case reports have noted analgesic effects in case reports in neuropathic pain and other pain disorders . An RCT of nabilone in 41 post-operative subjects actually documented exacerbation of pain scores after thrice daily dosing . An abstract of a study of 82 cancer patients on nabilone claimed improvement in pain levels after varying periods of follow-up compared to patients treated without this agent .
Furthermore, CBG has more potent analgesic, anti-erythema and lipooxygenase blocking activity than THC , mechanisms that merit further investigation. Cannabidiol, a non-euphoriant phytocannabinoid common in certain strains, shares neuroprotective effects with THC, inhibits glutamate neurotoxicity, and displays antioxidant activity greater than ascorbic acid or CBD gummies tocopherol . While THC has no activity at vanilloid receptors, CBD, like AEA, is a TRPV1 agonist that inhibits fatty acid amidohydrolase , AEA’s hydrolytic enzyme, and also weakly inhibits AEA reuptake . These activities reinforce the conception of CBD as an endocannabinoid modulator, the first clinically available . Additionally, CBD is able to inhibit tumor necrosis factor-alpha (TNF-α) in its own right in a rodent model of rheumatoid arthritis .
Phytocannabinoids are lipid soluble with slow and erratic oral absorption. While cannabis users claim that the smoking of cannabis allows easy dose titration as a function of rapid onset, high serum levels in a short interval inevitably result. As is evident in Figure 2 , all adverse events are more frequently reported with herbal cannabis, except for nausea and dizziness, both early and usually transiently reported with Sativex (see for additional discussion).
However, 17 subjects dropped out, and the study was neither randomized nor controlled, and therefore is not included in Table 1. Other “minor phytocannabinoids” in cannabis may also contribute relevant activity . Cannabichromene is the third most prevalent cannabinoid in cannabis, and is also anti-inflammatory , and analgesic, if weaker than THC . Cannabigerol displays sub-micromolar affinity for CB1 and CB2 . It also exhibits GABA uptake inhibition to a greater extent than THC or CBD , suggesting possible utilization as a muscle relaxant in spasticity.
Ajulemic acid (CT3, IP-751) , another synthetic dimethylheptyl analogue, was employed in a Phase II RCT in 21 subjects with improvement in peripheral neuropathic pain . Part of its analgesic activity may relate to binding to intracellular peroxisome proliferator-activator receptor gamma . Peak plasma concentrations have generally been attained in 1–2 hours, but with delays up to 4–5 hours is some subjects . Debate surrounds the degree of psychoactivity associated with the drug . Current research is confined to the indication of interstitial cystitis.
No dose tolerance to the therapeutic effects of Sativex has been observed in clinical trials in over 1500 patient-years of administration. The degree to which a drug is reinforcing is determined partly by the by the rate of its delivery to the brain .
No long-term mood disorders have been associated with Sativex administration. Debate continues as to the existence of a clinically significant cannabis withdrawal syndrome with proponents , and questioners . While symptoms recurred after 7–10 days of abstinence from Sativex, prior levels of symptom control were readily re-established upon re-titration of the agent .
