One study of 8 healthy volunteers and 15 patients with epilepsy, published in 1980 in Pharmacology, looked at the side-effects of CBD when consumed daily for a month. “All patients and volunteers tolerated CBD very well and no signs of toxicity or serious side effects were detected on examination,” wrote the researchers, who also found that CBD can help some people with epilepsy.
In a small study published in the journal JCI Insight in 2017, researchers observed that CBD may help prevent stress-related changes in blood pressure. For the study, nine healthy male volunteers took a single dose of either CBD or placebo. Compared to those given the placebo, those treated with CBD had lower blood pressure both before and after experiencing a stressful event.
That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.
There has been a raised concern of the effects and hidden dangers of inhaling the chemical propylene glycol, which is widely used to mix with CBD vape oil. Propylene glycol is a thinning compound and is also the primary ingredient in a majority of nicotine-infused e-cigarette solutions. At high temperatures, propylene glycol converts into toxic nanoparticles which are known for causing damage to respiratory organs and said to cause cancer, asthma, and other illnesses.
Using one kind whole-plant drawing system, the e-liquid has a full fat spectrum CBD blend with pure vegetable glycerine. Every bottle comes with 30ml of CBD and if you prefer dripping or even sub ohm tanks, this product is ideal. Indeed, lack of propylene glycol makes it hard for some clearomizers, but it’s a great product for people who love sub ohming.
I have Bipolar Disorder and took a capsule of CBD oil. It sedated me for over 24 hours, then left me depressed. I’ve taken cannabis edibles with THC in small amounts and was very happy with it’s temporary calming effects, headache relief and helping with sleep. People with Bipolar need to be very cautious with CBD oil or medicinal marijuana – keep it i. small amounts.
CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
The undisputed champion of terpenes is the cannabis plant. For so many, the blend of terpenes defines the cannabis experience. They can tell a story of composition, define a strain or pinpoint an origin. In fact, for many cannabis grow operations, retaining high terpene profiles is a driving goal. Not only do terpenes dictate flavor profiles, but also the effects – and science is just now beginning to explore the beneficial mechanisms at play.

Each bottle contains 200 drops, and Provacan recently increased the size of the larger option by 20%. If you choose the 1200mg option, you receive 6mg of CBD per drop in the 10ml bottle. The company has also boosted the terpene profile of its oil along with levels of additional cannabinoids, including CBG, CBC, THCa, and CBDv – all non-psychoactive compounds that do not produce a high.
