Which of the following is the primary non-psychoactive cannabinoid found in hemp?
CBD
Delta-9 THC
CBN
THC-A
CBD is the primary non-psychoactive cannabinoid found in hemp. Unlike THC, it does not produce a high and is widely used for therapeutic effects.
What is the main therapeutic role of CBD in anxiolysis?
NMDA receptor inhibition
Direct CB1 receptor agonism
Serotonin receptor modulation
GABA receptor antagonism
CBD exhibits anxiolytic effects primarily through interaction with serotonin 5-HT1A receptors. This modulation can help reduce anxiety without directly agonizing cannabinoid receptors.
Which molecular feature differentiates CBD from THC?
Absence of any aromatic ring in CBD
An open-ring structure in CBD versus a closed ring in THC
Lack of phenolic hydroxyl groups in CBD
A nitrogen atom in CBD's backbone
CBD has an open-ring structure, whereas THC features a closed cyclic pyran ring. This structural difference underlies the distinct pharmacological properties of the two compounds.
What is the maximum THC content allowed for industrial hemp under most regulations?
0.3% THC by dry weight
0.03% THC by dry weight
5% THC by dry weight
1% THC by dry weight
Industrial hemp is legally defined in many jurisdictions as cannabis containing no more than 0.3% THC by dry weight. This threshold distinguishes hemp from psychoactive cannabis varieties.
Which organization provides guidelines for pharmaceutical-grade CBD quality?
Environmental Protection Agency (EPA)
United States Pharmacopeia (USP)
International Organization for Standardization (ISO)
World Health Organization (WHO)
The United States Pharmacopeia (USP) sets quality standards for pharmaceutical-grade substances, including CBD. USP monographs outline testing procedures and purity criteria to ensure safety.
A 70 kg patient is prescribed 5 mg/kg/day of CBD. What is the total daily dose?
350 mg
175 mg
70 mg
500 mg
To calculate the daily dose, multiply the patient's weight by the prescribed mg/kg dosage. In this case, 70 kg × 5 mg/kg/day equals 350 mg per day.
CBD is metabolized primarily by which cytochrome P450 isoenzyme?
CYP3A4
CYP1A2
CYP2D6
CYP2C19
CBD is primarily metabolized by the cytochrome P450 enzyme CYP3A4 in the liver. This enzyme plays a major role in the oxidative metabolism of many cannabinoids.
Which medication interaction is most concerning when co-administered with CBD?
Vitamin C
Warfarin
Paracetamol
Insulin
CBD inhibits CYP2C9 and can increase levels of drugs metabolized by this enzyme, such as warfarin. Elevated warfarin levels can raise the risk of bleeding complications.
In a clinical case of pediatric epilepsy, what is the recommended starting dose of CBD?
10 mg/kg once daily
2.5 mg/kg twice daily
20 mg/kg twice daily
0.5 mg/kg once daily
Clinical guidelines for pediatric epilepsy often recommend initiating CBD at 2.5 mg/kg twice daily. This low starting dose helps monitor tolerability and side effects before titration.
A patient reports sedation after increasing their CBD dose. What is the best adjustment?
Add a stimulant
Reduce the CBD dose
Switch to THC-rich oil
Further increase the dose
If sedation occurs, reducing the CBD dose can alleviate side effects while maintaining therapeutic benefits. Dose adjustments should be gradual and monitored closely.
What is the significance of the 'entourage effect' in CBD therapy?
Artificial synergy in lab-made cannabinoids
Pure THC-driven effect
Synergistic interaction of multiple cannabis compounds
Effects of isolated CBD only
The 'entourage effect' describes the synergistic interaction of multiple cannabis compounds. This phenomenon suggests that combined cannabinoids and terpenes may enhance overall therapeutic effects.
Which route of administration yields the highest bioavailability of CBD?
Inhalation
Topical application
Oral capsule
Sublingual drops
Inhalation delivers CBD directly to the lungs and bloodstream, achieving the highest bioavailability. Oral and sublingual routes have lower absorption due to first-pass metabolism and mucosal limitations.
Under US federal law, hemp-derived CBD products are legal if they contain:
Over 0.5% THC by dry weight
No more than 0.3% THC by dry weight
Only synthetic cannabinoids
Derived from marijuana varieties
Under US federal law, hemp-derived products must contain no more than 0.3% THC on a dry weight basis. This legal definition allows hemp CBD to be sold nationwide.
Which label claim is prohibited for CBD products according to FDA guidelines?
Promoting skin hydration
Claims that CBD can treat cancer
Supporting general wellness
Improving mood
The FDA prohibits unsubstantiated disease treatment claims for CBD products. Claims suggesting CBD can treat cancer or other specific diseases are not allowed without approved drug status.
When counseling clients on CBD use, which factor is most important to assess first?
Favorite foods
Current medications
Hair color
Exercise routine
Assessing current medications is critical to identify potential drug interactions with CBD. Understanding a client's pharmacotherapy helps prevent adverse effects and ensures safe use.
The 'Δ9' notation in Δ9-THC refers to a double bond between which carbon atoms?
Between carbons 2 and 3
Between carbons 1 and 2
Between carbons 9 and 10
Between carbons 8 and 9
The 'Δ9' notation refers to the double bond between carbons 9 and 10 in THC's structure. This specific positioning distinguishes Δ9-THC from other isomers.
Calculate the concentration in mg/mL for a 20% w/v CBD tincture.
100 mg/mL
200 mg/mL
2 mg/mL
20 mg/mL
A 20% w/v solution contains 20 grams of CBD per 100 mL of solution. Converting grams to milligrams yields 200 mg/mL of CBD.
A patient on clobazam experiences increased sedation after starting CBD. What is the mechanism?
Induction of CYP3A4 increasing clobazam metabolism
Inhibition of CYP2C19 leading to higher clobazam levels
Increased renal clearance of clobazam
Activation of P-glycoprotein enhancing clearance
CBD inhibits the CYP2C19 enzyme, which metabolizes clobazam into its active metabolite. Inhibition leads to higher clobazam levels and increased sedation risk.
According to EU novel food regulation, CBD products intended for oral consumption require:
Prescription-only status
Novel food authorization before marketing
No regulation if under 0.3% THC
Manufacture under GMP without additional approval
In the EU, CBD is classified as a novel food, requiring authorization before being sold as food or supplement. Novel food approval ensures safety assessments and regulatory compliance.
In complex neurological conditions, why is CBD often preferred over THC?
Less clinical research evidence
Higher addiction risk
Stronger psychoactive effect
Lower psychoactivity and broader safety profile
CBD is favored in neurological conditions for its minimal psychoactive effects and favorable safety profile. Its broad therapeutic actions and low risk of intoxication make it preferable to THC.
