Overview - Cannabidiol (CBD)

Description of Cannabidiol (CBD)

Cannabidiol (CBD) was discovered in 1940. By 2021 there were 14 proposed members in the CBD family (i.e., CBD, CBDA-C5, CBDV, CBDM-C5, CBD-C1, CBD-C4, CBDVA-C3, CMPD1, CMPD5, CMPD6, CMPD16, CMPD18, CBDH, CBDB). CBD is a significant cannabinoid that occurs naturally in cannabis in amounts large enough to produce various and substantial changes in the human body, mind, and emotions.

Unlike its psychoactive sister, compound THC, CBD does not induce changes in cognition but is quite capable of generating a gentle uplift in affect (or mood), which is why the growing body of clinical trials indicates its therapeutic potential in several mood disorders or psychiatric conditions such as:

  • Alcohol Dependence, Withdrawal, and Intoxication

  • Anorexia Nervosa

  • Anxiety and Panic Disorders

  • Attention Deficit and Hyperkinetic Disorders

  • Autism and Pervasive Developmental Disorders

  • Behavioral Disorders

  • Benzodiazepine Use Disorder

  • Bipolar Affective Disorder

  • Cannabis Adverse Effects

  • Cannabis Use Disorder

  • Cocaine Dependence

  • Depression

  • Domestic Abuse

  • Grief, Bereavement, and Adjustment Disorders

  • Intermittent Explosive Disorder

  • Loss of Appetite

  • Nicotine Dependence and Withdrawal

  • Obsessive Compulsive Disorder

  • Opioid Dependency and Overdose

  • Post-Traumatic Stress Disorder

  • Psychosis

  • Schizophrenia

  • Stress and Life Management Difficulty

  • Suicide Attempt

  • Stimulant Dependence and Psychosis

  • Stuttering

Other Names:


(-)-Cannabidiol, (-)-trans-Cannabidiol, Epidiolex and other supplier-based synonyms.

IUPAC Name: 2-[(1R,6R)-3-methyl-6-prop-1-en-2-ylcyclohex-2-en-1-yl]-5-pentylbenzene-1,3-diol

Molecular Formula: C21H30O2


Cannabidiol (CBD) Properties and Effects

FDA approved (June 25, 2018) in the form of Epidiolex, a pharmaceutical version of CBD, for the treatment of rare pediatric seizure disorders that do not respond to orthodox anti-epileptics:

  • Lennox-Gastaut syndrome

  • Dravet syndrome

CBD is a multi-target molecule that binds with numerous cell receptors throughout the body; thus, it, directly and indirectly initiates complex biological changes to the body, mind, and emotion.

CBD Drug Interaction Potential: The latest review published in the Journal Seizure (March 2021) suggests that CBD interacts with anti-epileptic drugs through both pharmacodynamic (what the drug does to the body) and pharmacokinetics (what the body does to the drug) means primarily (but not exclusively) via the cytochrome p450 system.

Pharmacodynamic interactions with CBD:

  • Clobazam

  • Valproate

  • Levetiracetam

Pharmacokinetic interactions between CBD (frequently associated with CYP2C19 and CYP3A4):

  • Brivaracetam

  • Clobazam

  • Eslicarbazepine

  • Lacosamide

  • Gabapentin

  • Oxcarbazepine

  • Phenobarbital

  • Potassium bromide

  • Pregabalin

  • Rufinamide

  • Sirolimus/everolimus

  • Stiripentol

  • Tiagabine

  • Topiramate

  • Zonisamide

Cannabidiol (CBD) Receptor Binding

Endocannabinoid system (ECS) and CBD:

Numerous studies have posited complex and sometimes contradictory results in their findings and attempted to understand better the specific ways CBD may interact with CB1 and CB2. For instance, a review published in 2020 posits that CBD is an antagonist at CB1 and CB2 based on previous trial data (2007) that discovered that CBD decreased the potencies of the CB1 agonists THC and the power of the synthetic cannabinoid WIN55212 at CB2.

CBD inhibits the enzyme fatty acid amide hydroxylase (FAAH), which breaks down the body’s endocannabinoid anandamide (AEA), increasing its bioavailability and agonistic binding at CB1 and CB2 and their associated effects. Other researchers have resolved these contradictory interpretations by introducing the concept of CBD being an antagonist of CB1 and CB2 agonists. Other mechanisms by which CBD modulates the classical endocannabinoid receptors CB1 and CB2 are posited to include negative allosteric modulation at CB1.

Endocannabinoidome (eCBome) and CBD:

  • TRPA1

  • TRPV1 agonist with a Ki of 3600 ± 200nM (J. McPartland et al., 2015)

  • TRPV2

  • TRPM8 antagonist with a mean EC50 = 70.0 ± 14.1nM using data from 2 trials (J. McPartland et al., 2015)

  • Dopamine 2 (D2) receptor sites (via partial agonism)

  • GPR3 (via inverse agonism)

  • GPR6 (via inverse agonism)

  • GPR12 (via inverse agonism)

  • GPR55 (via antagonism)

  • PPAR-gamma (via agonism)

  • Ca2+ channels (as an inhibitor)

  • Na+ channels (as an inhibitor)

  • Adenosine 1 channel (via agonism)

  • Adenosine 2 channel (via agonism)

  • Serotonin 5‐HT1A receptor (via agonist activity)

  • Modulation of mu-opioid receptor sites (MOR) (via negative allosteric modulation)

  • Modulation of delta-opioid receptor sites and (DOR) (via negative allosteric modulation)

Ki legend:

  • Full/strong agonist Ki ~1-9nM

  • Moderate agonist Ki ~10-99nM

  • Weak agonist Ki ~100-999nM

  • Very weak agonist Ki ~1,000-up nM

(The reader is reminded that a smaller Ki is associated with the most potent effects.)
