These trichomes are tiny, hair-like crystals that cover the leaves and buds of the cannabis plant. Trichomes product the hundreds of known cannabinoids that can be found in cannabis. Of the 100+ cannabinoids that have been identified in the cannabis species, CBD and THC have been studied the most extensively for their role in the endocannabinoid system.
It is thought that by applying the correct amount of cannabis, the cannabinoids can help with the promotion of lipids which help fight chronic skin conditions including acne and psoriasis. Some also claim that cannabis oil has the power to remove wrinkles and skin spots. While we wouldn’t bank on it being the “anti-aging” miracle, it is helping millions of people worldwide deal with a variety of skin diseases including eczema and rosacea.
Cunha et al. reported a 2-phase pilot study of CBD versus placebo in normal volunteers and patients with refractory secondarily generalized epilepsy (14). In the first phase, 8 normal volunteers received CBD or placebo in a doubled-blind fashion, at a dose of 3 mg/kg for 30 days. The second phase was also double-blinded in 15 patients with epilepsy receiving 200 to 300 mg daily of CBD or placebo for 135 days. Patients continued baseline AED. All subjects tolerated CBD well, with no serious adverse events. Four of the epilepsy patients receiving CBD were “almost free of convulsive crisis” for the duration of the study. Three other patients receiving CBD had a partial reduction in seizures, and 1 subject had no response. Of the 7 patients receiving placebo, seizure frequency was unchanged in 6, and 1 had clear improvement in seizure control.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
Thank you. I am 81 and started the CBD drops night and morning. I sleep better and no longer suffer the excruciating pain from diverticulitis. I saw somewhere that for my asthma I need the THC so got some (totally illegal here in South Africa). I think it is helping. The diagnosis of COPD was made some years ago and as a health psychologist I do all I can to remain healthy for my 97th birthday!! (Both my grandmother and greatgrandmother did so I believe I will too).

CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.
Luckily, it’s possible to procure CBD oil that has no THC in it. Products made from CBD Isolate or Broad Spectrum CBD can be good options if you want to avoid THC. In fact, some of the best CBD products for pain include topical salves that can be made from isolate CBD oil. Just be sure to check out third-party lab reports to ensure you’re getting exactly what you pay for. And keep your eyes peeled for future research on CBD for pain.

Sub-lingual CBD drops have helped me enormously with sleeping and with radiation damage pain. I have a cancer that spread from the pelvic area to my sacrum and sciatic nerve and whilst the chemo and radiotherapy saved my life I have been taking MST (morphine derivative) for nerve pain ever since. My tumours are presently all quiet and last March I decided I wanted to stop taking the pain relief drugs, fearing dementia. CBD oil was recommended by my son who has arthritis and, for me, it really works. It’s so good to read an article that isn’t put out by a CBD sales site – I wish it could be properly prescribed and regulated (I’m in the UK) in order to have confidence with purity and dosage.


The furry subjects, 277 Wistar rats, were given a dose of CBD immediately after receiving a small electric shock. The CBD-treated subjects were found to spend less time frozen in fear when reintroduced to the context of the fearful event. This means the CBD disrupted consolidation (or more simply put: memory strengthening) of their specific and long-term fear memory.
Researchers at the Department of Pharmacognosy, The School of Pharmacy, University of London, UK, basis the study conducted on mice found that CBD oil has analgesic properties and may relieve chronic pain of all kinds . It can disrupt the activity of pain receptors in the body and instead cause a release of neurotransmitters such as serotonin and dopamine – “feel good” compounds that can ease discomfort and pain, even if the pharmaceutical painkillers have no effect.
Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.
CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.
There’s a growing consensus that cannabis is a highly effective treatment for many kinds of neuropathic pain. A 2015 study published in Neurotherapeutics states, “Clinical studies largely affirm that neuropathic pain patients derive benefits from cannabinoid treatment.”   But much of the human-based research (like this study) on CBD and nerve pain has centered around the efficacy of the FDA-approved medication Sativex, which includes both THC and CBD. Research on the best CBD for pain isolated from THC is still limited when it comes to neuropathic pain. There are exceptions, though:
Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.
CBD may be best known for its relaxing, calming effects. CBD reduces autonomic arousal, having the inverse effect of THC on the body. CBD’s anti-anxiety effect is why many in the cannabis community talk about how CBD relieves paranoia, although that is not scientifically proven yet. CBD is also known for its anti-nausea and pain relieving effects. It really depends on why your body’s specific needs and the quantity in which you take CBD.
If you’re ready to get your CBD on, picking any of these high-quality vape liquids will give you the best possible introduction to this wildly popular substance. The VaporVanity editorial team has verified that these are some of the best CBD vape oils on the market today, so you can rest easy knowing that as long as you choose from this list, any choice you make is certain to be a good one.
Vape Pens – Perhaps the easiest way to get the CBD Oil into your body is through a vape pen. A vape pen is about the size of an ink pen but has a CBD oil cartridge with a heating element. Many people like vape pens because there is very little in the way of odor after using it and it allows for a lot of discretion because it can be pulled out of your pocket and used on demand.
