Cannabidiol (CBD)

Overview

Cannabidiol (CBD) is a phytocannabinoid derived from the Cannabis sativa plant, specifically from hemp, which contains minimal amounts of tetrahydrocannabinol (THC), the psychoactive component of cannabis^[1]. CBD is non-psychoactive and has been studied for its potential therapeutic benefits, including its use in treating certain forms of epilepsy, anxiety, and pain^[2]. Historically, CBD was first isolated in 1940, but it gained significant attention in recent years due to its medical applications^[3].

Forms and Variations

CBD is available in various forms, including:

• CBD Oil: Contains only CBD as the active ingredient.
• CBD-Dominant Hemp Extract Oil: Includes other compounds from the hemp plant.
• Capsules: Convenient for precise dosing.
• Topicals: Applied directly to the skin for localized effects.

These forms allow users to choose how they prefer to consume CBD based on their needs and preferences.

Dosage and Administration

The optimal dosage of CBD varies widely depending on the condition being treated and individual tolerance. Common dosages range from 5 mg to 50 mg per day, often taken orally or sublingually^[5]. For best results, it is recommended to start with a low dose and gradually increase as needed. CBD can be taken with food to enhance bioavailability^[3].

Scientific Research and Mechanism of Action

CBD has been extensively studied for its anticonvulsant properties, particularly in treating severe forms of epilepsy like Dravet syndrome and Lennox-Gastaut syndrome^[1]. It interacts with various neurotransmitters and may modulate the effects of THC^[3]. While research suggests potential benefits for anxiety, pain, and other conditions, more rigorous studies are needed to confirm these effects^[5].

Benefits and Potential Uses

CBD is most notably effective in treating certain seizure disorders, with FDA-approved Epidiolex being used for this purpose^[2]. Potential uses include managing anxiety, pain, and sleep disturbances, though evidence is largely anecdotal or based on preliminary studies^[4]. CBD also exhibits anti-inflammatory and antioxidant properties, which may contribute to its therapeutic potential^[4].

Side Effects and Risks

Common side effects of CBD include drowsiness, changes in appetite, and diarrhea^[5]. While generally considered safe, CBD can interact with certain medications, such as blood thinners, and may not be suitable for everyone, especially pregnant or breastfeeding women^[3].

Interactions and Precautions

CBD may interact with medications like antacids, blood thinners, and certain antidepressants^[3]. Individuals with liver conditions should use caution due to CBD"s metabolism in the liver. Before starting CBD, especially if you are on other medications, consult with a healthcare provider^[5].

Impact on Biomarkers

CBD may affect liver function tests due to its metabolism by liver enzymes. Regular monitoring of liver enzymes is recommended for long-term users^[3].

Overdose and Toxicity

While CBD is generally well-tolerated, high doses may exacerbate side effects like drowsiness and changes in appetite. There is no established safe upper limit, but doses above 1,500 mg per day are not typically recommended^[5].
