Cannabinoids: CBD, CBN and CBG, where to start
CBD, CBN, CBG: the shelf has a few letters beyond CBD that you may not recognise yet, and oils, capsules and gummies each come with their own way of counting a serving.
This is the home for everything we have on cannabinoids: what CBD is, how the other cannabinoids differ, how the formats compare and where safety and the rules come in. It is for anyone curious about these products, whether you are just looking or comparing labels.
Where to start
- CBD is new to me. Begin with CBD: the ingredient, the labels and the questions, then move on to the formats.
- I am comparing products. Read CBD Oil, Capsules and Gummies: What the Label and the Evidence Actually Tell You for label arithmetic, then the CBN and CBG guide if the label lists them.
- I take medication, or have a safety or legal question. Go to CBD Safety and Drug Interactions: Liver, Medicines, Pregnancy and Driving or Is CBD Legal in Europe? EU Law and the Dutch Position before anything else.
The guides, in reading order
- CBD: the ingredient, the labels and the questions: What is CBD, which of its reputations have trial evidence and how do you read an oil label?
- CBD Oil, Capsules and Gummies: What the Label and the Evidence Actually Tell You: What does each format change, and how do you turn a label into milligrams per serving?
- CBN and CBG: how do they differ from CBD?: Where do CBN and CBG come from, and why does evidence for one not carry over to the others?
- CBD Safety and Drug Interactions: Liver, Medicines, Pregnancy and Driving: What do trials show about liver effects, sleepiness and medicines, and who should ask a pharmacist first?
- Is CBD Legal in Europe? EU Law and the Dutch Position: How do EU novel food rules, THC figures and national law fit together?
Before you buy anything
Rules for cannabinoid products differ between countries and product types, and they change. The legal guide is the place to check them, and the interactions guide covers medicines, pregnancy and driving.
