Beginner’s Guide

Project CBD was established in 2010 by journalists who had been covering the medical marijuana story — the science, the movement and the industry. We felt that the reintroduction of CBD-rich cannabis into the grassroots supply merited special attention. The serendipitous reappearance of whole plant CBD in Northern California in 2009 has given doctors and patients a unique opportunity to evaluate the effects of cannabidiol. Project CBD updates doctors and patients on developments in cannabis science, therapeutics and political economy.

What is CBD?

CBD is a non-intoxicating part of the cannabis plant with enormous healing potential. Although CBD doesn’t make people feel high, it’s causing quite a buzz.

CBD Oil: An Introduction

Medical patients swear by it. Researchers are intrigued by it. Government regulators are flustered by it. And investors are head over heels for it. But what exactly is CBD oil?

CBD & THC: Myths and Misconceptions

CBD and THC are the power couple of cannabis therapeutics, interacting to amplify one another’s curative properties. CBD enhances THC’s painkilling and anticancer properties, while lessening THC’s psychoactivity.

What Is the Best Way to Take CBD?

CBD-rich cannabis oil products can be taken sublingually or orally, applied topically, or inhaled with a vape pen. The time of onset and duration of effect vary depending on the method of administration.

CBD & Cannabis Dosing

There is no single ratio or strain that’s right for everyone. A person’s sensitivity to THC is a key factor in determining the appropriate ratio and dosage of CBD-rich medicine. You need to find the combination of CBD and THC that works best for you.

How Do I Choose a CBD Product?

Look for products with clear labels showing the quantity and ratio of CBD and THC per dose, a manufacturing date, and a batch number (for quality control). Select products with quality ingredients that are lab tested and safely extracted.

Cannabis Oil vs. Hemp Oil

Compared to whole plant CBD-rich cannabis, industrial hemp grown for fiber or seed is typically low in cannabinoid content. If you live in a state where medical marijuana is legal and available, look for CBD products made from cannabis.

Is "Pure" CBD Better?

Scientific studies have established that synthetic, single-molecule CBD has a narrow therapeutic window and requires high doses for efficacy as compared to whole-plant, cannabis-derived CBD.

CBD Drug Interactions: What You Need to Know

CBD is a very safe substance, but it can interact with many common pharmaceuticals. At sufficient dosages, CBD will deactivate cytochrome P450 enzymes, thereby altering how we metabolize painkillers, statins, blood thinners, insulin, and other drugs.

CBD User's Guide

Many health professionals have little to no experience with cannabis therapeutics and are not able to guide people on this subject. So Project CBD has created a beginner’s guide to cannabidiol & cannabis therapeutics to address key questions of CBD users.
