CBD, or cannabidiol, is one of the primary naturally occurring compounds found in the cannabis plant. It belongs to a group of plant chemicals known as cannabinoids, which interact with the body’s endocannabinoid system (ECS).

Unlike THC (tetrahydrocannabinol), CBD is not considered intoxicating and generally does not produce the “high” commonly associated with cannabis. Because of this, CBD has become one of the most widely studied cannabinoids for its potential role in supporting health and symptom management.

Researchers continue to investigate CBD for a variety of medical conditions, although additional high-quality clinical studies are needed to fully understand its benefits, risks, and long-term effects.

CBD is naturally produced by the cannabis plant.

Like THC, CBD is found primarily in the plant’s trichomes, the tiny crystal-like glands that cover mature cannabis flowers.

Both marijuana and hemp plants contain CBD, although the amount of CBD and THC varies depending on the plant’s genetics and how it was cultivated.

Some cannabis varieties are bred to contain high levels of CBD with very little THC, while others contain a combination of both cannabinoids.

CBD works differently than THC.

Rather than strongly binding to CB1 receptors in the brain, CBD appears to influence multiple signaling pathways throughout the body, including some associated with the endocannabinoid system (ECS).

Scientists believe CBD may help support the body’s natural ability to maintain balance, or homeostasis, although researchers are still learning exactly how CBD produces its effects.

CBD may also interact with other receptors involved in pain, inflammation, mood, and nervous system function.

Unlike THC, CBD generally does not produce intoxication or significant impairment.

Researchers continue to study CBD for its potential role in supporting patients with conditions involving:

• Chronic pain
• Inflammation
• Anxiety
• Seizure disorders
• Sleep disturbances
• Muscle discomfort
• Stress-related conditions

Although research is promising in several areas, results vary depending on the condition being studied, the dose used, and the individual patient.

CBD continues to be studied in both laboratory and clinical settings.

Current areas of research include:

• Epilepsy
• Chronic pain
• Anxiety disorders
• PTSD
• Inflammatory conditions
• Arthritis
• Multiple sclerosis
• Sleep disorders
• Neurological diseases
• Migraine
• Digestive disorders

Researchers continue to investigate how CBD may be used as part of comprehensive medical care for these and other conditions.

No.

CBD is not generally considered intoxicating and does not typically produce the euphoric effects associated with THC.

Many patients prefer CBD-containing products because they may provide therapeutic effects without causing significant impairment.

Some products, however, contain both CBD and THC, so patients should always review product labels carefully.

CBD and THC are the two most abundant cannabinoids found in cannabis.

Although they share a similar chemical structure, they affect the body differently.

CBD

• Not generally intoxicating
• Does not typically produce a “high”
• Influences multiple biological pathways
• Continues to be studied for inflammation, anxiety, seizures, and pain

THC

• Psychoactive
• Produces intoxication
• Primarily binds to CB1 receptors
• May help manage pain, nausea, appetite loss, and muscle spasticity

Many medical cannabis products combine CBD and THC in different ratios to meet individual patient needs.

Medical cannabis products are often labeled with a ratio describing the amount of CBD compared with THC.

Examples include:

• 20:1 CBD to THC
• 10:1 CBD to THC
• 4:1 CBD to THC
• 1:1 CBD to THC

Different ratios are selected based on patient preferences, treatment goals, and physician recommendations.

Because every patient responds differently, finding the appropriate ratio often requires individualized guidance.

CBD is available in many different forms.

These include:

• Oils
• Tinctures
• Capsules
• Gummies
• Edibles
• Beverages
• Topical creams
• Lotions
• Balms
• Transdermal patches
• Vape cartridges
• Flower

Each method of administration has different onset times, durations, and dosing considerations.

CBD is generally well tolerated by many individuals, but like any supplement or medication, it may cause side effects.

Possible side effects include:

• Drowsiness
• Dry mouth
• Fatigue
• Diarrhea
• Changes in appetite
• Lightheadedness

Not everyone experiences side effects, and many are mild and temporary.

Patients should always discuss CBD use with their healthcare provider, especially if they take prescription medications, as CBD may interact with certain drugs.

Yes.

CBD may affect how the body processes certain medications by influencing liver enzymes responsible for drug metabolism.

Examples include some medications used for:

• Blood thinning
• Seizure disorders
• Heart disease
• Organ transplantation
• Depression
• Anxiety

Patients taking prescription medications should consult their healthcare provider before adding CBD to their treatment plan.

Not all CBD products are manufactured the same way.

Patients should look for products that:

• Are laboratory tested by independent third-party laboratories
• Clearly list CBD content
• Provide ingredient information
• Meet California regulatory requirements
• Are purchased from licensed retailers when applicable

Laboratory testing helps consumers better understand the cannabinoid content and quality of the products they purchase.

CBD remains one of the most actively studied cannabinoids.

Researchers around the world continue to investigate:

• Chronic pain
• Anxiety disorders
• Epilepsy
• Sleep disorders
• Inflammation
• Neurodegenerative diseases
• Autoimmune conditions
• Mental health
• Quality of life

As research advances, scientists continue to improve our understanding of how CBD interacts with the body and how it may be incorporated into evidence-based medical care.
