Frequently Asked Questions

We recommend starting off with our low dose 2-bottle set of day and night 750mg full spectrum combo. Each 1 ml dropperful contains 25 mg of CBD.

There are added terpenes in the Daytime formula for focus and energy, and calming terpenes in the Night-time formula. We prefer the Full Spectrum with a trace of THC over the THC-free, as it is the most robust formula. Dosing is very individual - no “one size fits all” here. Start low, like a ½ dropper under the tongue for 30-60 secs, and gradually increase the amount till you get to the most effective dose for your purposes. See details here.

Yes! We recently changed the label design and the name, but it’s the exact same product that you have been getting, i.e. THC-free 2 oz. The official nomenclature changed, so what we used to call our THC-free Full Spectrum is now called THC-free Broad Spectrum.

Our label design on the 2 oz bottles also changed to match the new 1 oz tinctures of Full Spectrum 1 oz (with THC 0.3%), and Isolate (no THC), topicals, and our pet product. It’s all described here.

All our products are independently third-party tested for purity and content. We provide Certificates of Analysis (COAs) to show exactly what is in our products-and what is not. You can check the Certificates of analysis of each of our products here.

Our Anytime formula has no added day or night terpenes, so can be used at any time for a positive effect. Individual responses vary, too. The Daytime version can be taken in the morning and throughout the day for a focused, centered, and calm day. Take the Night-time formula for restful sleep and restoration of your body, mind, and spirit. To avoid daytime drowsiness it should be used only at night.

To promote a good night’s sleep, we suggest you try our Night Time Hemp Oil Tincture. It is a perfect blend of calming and relaxing terpenes to lull you into a deep and restful sleep, awakening refreshed. You can also add in our Hemp Oil/CBD Extract Melatonin Vegan Capsules for an even more sustained effect. You would take both at bedtime -- the tincture for immediate onset and the capsule for a little later onset and longer-lasting effect.

CBD is often used to ease normal aches and pains and such as soreness from muscle exertion. You can take it orally or as a topical salve - or both for maximum effect. For more information, we suggest you do your own research, talk to your doctor and refer to our testimonials and blogs.

With no research to back it, we’re unable to recommend the use of CBD during pregnancy If you are pregnant or nursing consult your health care provider about taking hemp oil extract/CBD.

No. Our Dr. Cass’ Hemp Oil/CBD products are grown from seeds that produce plants that are extremely low in THC and high in CBD. As a result, our Dr. Cass’ Hemp Oil/CBD products have a THC concentration of less than the 0.3% that meets Federal regulations. The trace amount of THC, combined with other natural cannabinoids and terpenes found in hemp plants, work synergistically for the entourage effect to maximize the efficacy of our products. But they won’t get you high!

You do not need a prescription to purchase Dr. Cass’ Hemp Oil/CBD. However, we recommend that you consult your health professional before using this product, just as you should with any other nutritional supplement. This is especially true if you are pregnant, trying to get pregnant, are nursing, or if you are taking a prescription medication and are concerned about possible interactions. You’ll find more information in this Guide.

Although Dr. Cass’ Hemp Oil/CBD Full Spectrum is in full compliance for the allowable THC levels in hemp, it does have a trace amount of 0.3% or less. While the likelihood of a failed drug test would be quite low, THC can actually concentrate in your fat cells over time, we cannot guarantee that it won’t happen. So if you are subject to random testing for THC, we recommend that you take Dr. Cass’ Hemp Oil/CBD 1 oz THC-Free tinctures and capsules instead.
