About CBD: What It Is, How It Works, and What the Science Says

What Is CBD?

CBD (cannabidiol) is a compound found in hemp and cannabis plants. Of the 100+ cannabinoids in cannabis, CBD is the second most abundant after THC.

CBD is non-psychoactive. It does not produce a high, alter perception, or impair cognition. You stay clear-headed. This distinction drives CBD's adoption in wellness, food, and beverages.

Chemist Roger Adams first isolated CBD in 1940 at the University of Illinois. Raphael Mechoulam described its full structure in 1963. Thousands of peer-reviewed studies have followed.

CBD vs. THC: What is the Difference?

Both come from cannabis. They do different things in your body.

You can drink CBD coffee, drive to work, and operate at full capacity.

The Endocannabinoid System (ECS)

Researchers discovered the endocannabinoid system (ECS) in the early 1990s. It is your body's largest neurotransmitter system. Harvard Health calls it "essential and mysterious."

The ECS maintains homeostasis, your body's internal balance. It regulates:

• Sleep and circadian rhythm
• Mood and emotional processing
• Stress response
• Pain perception
• Inflammation and immune response
• Appetite and metabolism
• Memory and learning
• Temperature regulation

The ECS has three core components:

You have an endocannabinoid system whether or not you have used cannabis. It runs all the time, adjusting your biology to stay in balance.

How CBD Works in Your Body

THC binds directly to CB1 receptors in your brain. That is what causes a high. CBD works differently. It influences the ECS without binding to those receptors.

Five Mechanisms of Action

Scientists have identified over 65 molecular targets of CBD. The five primary ones:

• Enzyme inhibition: CBD may slow the breakdown of anandamide (your body's natural "bliss molecule") by inhibiting the FAAH enzyme. More anandamide in your system means more of your body's own calming signals stay active longer.
• Allosteric modulation: CBD acts as an allosteric modulator at CB1 receptors. Think of it as a dimmer switch: it does not turn the receptor on or off, but adjusts the volume. This is why CBD can moderate the effects of THC.
• Serotonin receptor activation: CBD activates the 5-HT1A serotonin receptor, which plays a role in anxiety, mood, and pain perception. This may explain CBD's calming and anti-anxiety effects.
• TRPV1 receptor activation: CBD activates vanilloid receptors (TRPV1), which are involved in pain perception, inflammation, and body temperature.
• Immune signaling pathways: CBD modulates the immune response by interacting with adenosine receptors and reducing the release of pro-inflammatory cytokines.

Types of CBD: Full-Spectrum, Broad-Spectrum, and Isolate

The extract type determines which hemp compounds survive alongside CBD.

The Entourage Effect

Cannabinoids, terpenes, and flavonoids may work better together than any single compound alone. Researchers call this the entourage effect. Full-spectrum and broad-spectrum extracts keep these compounds intact.

Terpenes: The Aromatic Compounds in Hemp

Cannabis contains over 500 compounds. Terpenes are the aromatic molecules behind the plant's scent and flavor. Lavender, citrus, and pine trees produce them too. In hemp, terpenes may amplify CBD's effects through the entourage effect.

Key Terpenes in Hemp

Broad-spectrum products retain these terpenes. Isolate strips them out. Buddha Beans keeps them in.

CBD Bioavailability: How Your Body Absorbs It

Your body does not absorb all the CBD you consume. How you take it determines how much reaches your bloodstream.

CBD Dosage: How Much Should You Take?

No universal dose exists. Your body weight, chemistry, and goals all factor in.

General Guidelines

The "Start Low and Go Slow" Method

The most widely recommended approach from both clinicians and researchers:

1. Week 1: Start with the lowest dose (one cup of standard CBD coffee, approximately 10mg)
2. Week 2: If you do not feel effects, increase slightly (add a second cup or switch to Black Label)
3. Week 3+: Continue adjusting by small increments until you find your personal sweet spot
4. Maintain: Once you find an effective dose, stay consistent. Many users report that daily use produces the best results as CBD builds up in your system over time

Studies have used doses up to 1,500mg per day without serious adverse effects. At the doses found in CBD coffee (10-30mg per cup), side effects are extremely rare.

What Researchers Are Studying About CBD

This section summarizes published research on cannabidiol as a compound. It is education, not a description of what our coffee does. Most of this work is preclinical or early-stage, and Buddha Beans makes no health claims for any product we sell.

Stress and Mood Research

This is the most studied area. Published double-blind, placebo-controlled trials have measured self-reported stress and mood outcomes, and researchers point to serotonin receptor (5-HT1A) activity and the endocannabinoid system as candidate mechanisms. That describes the literature on isolated cannabidiol, not our coffee.

Researchers have examined serotonin signaling in this work. These are research questions under investigation, not established outcomes, and nothing here is a claim about a coffee product.

Sleep Research

A case series published in The Permanente Journal reported sleep-score changes in 66.7% of patients within the first month, and a 2024 study compared 15mg of CBD with 5mg of melatonin on sleep-quality measures. Those are the published findings for isolated cannabidiol under study conditions. We make no sleep claims for our coffee, which contains caffeine.

Pain and Inflammation Research

Preclinical work, meaning animal and cell studies rather than humans, has examined CBD's interaction with TRPV1 receptors, adenosine receptors, and immune cell signaling. Survey data indicates pain is a common self-reported reason people try CBD. Preclinical results frequently do not replicate in humans.

Neurological Research

The FDA has approved Epidiolex, a prescription drug containing purified cannabidiol, for two rare seizure disorders. That approval applies to a regulated pharmaceutical at prescription dosing under medical supervision. It says nothing about coffee, and no food or beverage containing CBD is approved to treat any condition.

Digestive Research

Cannabinoid receptors are present in the digestive tract, and preclinical studies have examined cannabinoid activity there. This research is early and we make no digestive claims for our coffee.

Dermatology Research

Most skin-related cannabinoid research studies topical application, not ingestion, and the work is largely preclinical. Drinking coffee is not a skincare treatment and we make no skin claims.

Inflammation Research

In laboratory studies researchers have measured cannabidiol's effects on inflammatory signaling markers. That laboratory activity is why the compound continues to be studied across several areas. None of it is an established outcome in people drinking coffee.

Antioxidant Activity

The U.S. government holds a patent (US6630507B1) on cannabinoids as antioxidants and neuroprotectants. Coffee is a major source of antioxidants in the average Western diet. We mention the patent because it exists, not as a claim about what our coffee does for you.

Safety and Side Effects

The World Health Organization reviewed CBD in 2018. Their conclusion: "generally well tolerated with a good safety profile." They also found "no effects indicative of any abuse or dependence potential."

Possible Side Effects

At 5 to 50mg, side effects are uncommon. When they show up, they are mild:

• Dry mouth
• Drowsiness (more common at higher doses)
• Reduced appetite
• Mild digestive changes
• Fatigue

Drug Interactions

Your liver metabolizes CBD through the cytochrome P450 enzyme system. Many prescription drugs use the same pathway. If your medication carries a "grapefruit warning," talk to your doctor before using CBD. Blood thinners, seizure medications, and immunosuppressants are the biggest concerns.

Who Should Avoid CBD?

• Pregnant or breastfeeding individuals
• People taking medications that interact with grapefruit
• Children (unless under medical supervision, such as Epidiolex)
• Anyone with liver conditions (discuss with your doctor first)

Legal Status of CBD

Federal Law (United States)

The 2018 Farm Bill removed hemp from the Controlled Substances Act. Hemp and CBD regulations have continued to change since then at both the federal and state level, so current rules are best checked locally. Hemp: cannabis with less than 0.3% THC on a dry weight basis.

FDA Regulation

The FDA retains authority over hemp products. They have not approved CBD as a food additive or dietary supplement (Epidiolex, a prescription drug, is the exception). CBD products sell across all 50 states. The FDA focuses enforcement on companies making false medical claims, not on responsible CBD food and beverage brands.

State Laws

Most states follow federal law in permitting hemp-derived CBD. A small number of states have additional restrictions. CBD products with zero THC (like Buddha Beans broad-spectrum CBD coffee) face the fewest legal restrictions in any jurisdiction.

International

CBD's legal status varies by country. In the EU, CBD products must contain less than 0.2% THC. In the UK, CBD is legal as a "novel food." In Canada, CBD is regulated under the Cannabis Act. Always check local laws if traveling with CBD products.

How to Evaluate CBD Quality

The CBD market is largely unregulated, which means quality varies dramatically. Here is what to look for:

1. Third-Party Lab Testing (COA)

The single most important quality indicator. A Certificate of Analysis from an independent lab verifies the CBD content, THC levels, and absence of contaminants. If a company does not publish COAs, avoid their products.

2. Hemp Source

Look for USDA Organic certification or hemp sourced from reputable U.S. farms. Organic hemp is grown without synthetic pesticides or herbicides. Hemp is a bioaccumulator, meaning it absorbs whatever is in the soil, making sourcing critically important.

3. Extraction Method

CO2 extraction is the gold standard. It produces clean, solvent-free CBD extract without chemical residues. Ethanol extraction is also acceptable. Avoid products extracted with butane or other harsh solvents.

4. CBD Type and Dosage

Know whether the product uses full-spectrum, broad-spectrum, or isolate CBD. Check the dosage per serving. Reputable brands clearly state the milligrams of CBD per unit (per cup, per gummy, per dropper).

5. No Medical Claims

Responsible CBD companies do not claim their products cure, treat, or prevent diseases. They present research, share their testing, and let you make informed decisions. Be skeptical of any brand making miracle-cure claims.

CBD and Coffee: Why They Work Together

Coffee and CBD affect your body through different but complementary pathways. Here is why the combination makes sense:

Caffeine + CBD: Complementary Mechanisms

CBD coffee gives you the energy you want from caffeine while reducing the side effects: jitters, anxiety, stomach acid, the crash.

Caffeine blocks adenosine receptors, promoting alertness. CBD modulates the stress response through a separate pathway. Two systems, one cup. Our customers call it "jitterless, focused energy."

Safety Data

A 2024 study tested CBD and caffeine together. No negative interactions. No altered subjective effects. Early safety data confirms what coffee drinkers have reported for years.

Infusion vs. Spraying

Most CBD coffee brands spray oil onto pre-roasted beans. Buddha Beans infuses CBD into the bean during roasting (our ZenFusion method). The difference: even distribution, consistent dosing per cup, no oily residue, no hemp aftertaste.

Dosing

Our standard CBD coffees contain approximately 10mg of CBD per cup. Our Black Label line contains 20mg+ per cup. For detailed dosing guidance, see our CBD Coffee Dosage Guide.

Frequently Asked Questions About CBD

Will CBD show up on a drug test?

Standard drug tests screen for THC, not CBD. Broad-spectrum CBD (which Buddha Beans uses) contains zero THC, minimizing this risk. Full-spectrum products with trace THC could potentially trigger a positive result with very heavy use. No product can guarantee a negative drug test, but THC-free products like ours carry the lowest risk.

How long does CBD take to work?

When consumed in coffee or food, CBD typically takes 30 to 60 minutes to take effect. The duration is usually 4 to 6 hours. Sublingual (under-the-tongue) CBD oils work faster (15 to 30 minutes) because they bypass digestion. Inhaled CBD works within minutes but has a shorter duration.

Can I take too much CBD?

CBD has a very high safety ceiling. Studies have used doses up to 1,500mg per day without serious adverse effects. That said, more is not always better. Most people find their optimal dose between 10 and 50mg per day. Start low (one cup of CBD coffee) and adjust based on how you feel.

Is CBD addictive?

No. The World Health Organization's 2018 report found that CBD "exhibits no effects indicative of any abuse or dependence potential." CBD does not produce euphoria, tolerance buildup, or withdrawal symptoms.

Can I give CBD to my pet?

Many pet owners use CBD for their dogs and cats. However, CBD coffee is not appropriate for pets due to the caffeine content. If you are interested in CBD for your pet, consult your veterinarian and use a pet-specific CBD product.

Does CBD interact with alcohol?

CBD and alcohol may amplify each other's effects. Both can promote relaxation and sedation, so combining them at high doses may increase drowsiness. At the low doses found in CBD coffee, this interaction is generally not a concern.

How should I store CBD products?

Store CBD coffee in a cool, dry, dark place, just like regular coffee. CBD degrades with prolonged exposure to heat, light, and oxygen. Sealed bags stored in a pantry are ideal. CBD coffee typically maintains potency for 6 to 12 months.

What is CBG and how is it different from CBD?

CBG (cannabigerol) is known as the "mother cannabinoid" because all other cannabinoids are synthesized from it. Like CBD, CBG is non-psychoactive. Research suggests CBG may be particularly effective for focus, gut health, antibacterial activity, and neuroprotection. Buddha Beans offers both CBD and CBG coffee products.
