Spray

CBD spray is an oral and sublingual form of supplementation with cannabidiol, which is increasingly replacing traditional oils — a precise spray under the tongue delivers a measured dose of CBD directly to the mucous membrane, without the need for measuring with a dropper. On this page, you will find all CBD sprays available at u Bucha: Reakiro products in full spectrum and broad spectrum versions from 1000 mg down 6000 mg CBD in a 30 ml bottle, alongside supplements supporting natural detoxification after cannabis products. Read this page to learn how to choose the right concentration, how to properly use the spray, and what distinguishes broad from full spectrum.

How to choose a CBD spray?

Choosing the right CBD spray starts with three variables: the spectrum of the extract, the concentration of CBD per dose, and the purpose of use. A study published in Cannabis and Cannabinoid Research (2020) has shown that the sublingual route allows for the absorption of CBD within minutes, making sprays one of the fastest-acting forms of oral administration.

Extract spectrum — full spectrum contains all natural cannabis cannabinoids, including trace amounts of THC (up to 0.2% THC according to EU law requirements), which promotes the entourage effect. Broad spectrum is CBD without detectable THC — an option for those who want to avoid even trace amounts of THC. Before deciding, read our complete guide to types of CBD, which compares isolate, full, and broad spectrum point by point.

CBD concentration and dosing — the sprays offered at u Bucha range from 1000 mg down 6000 mg CBD in a 30 ml bottle. The standard pump doses approximately 0.14 ml, which at a concentration of 1000 mg/30 ml provides approximately 4.7 mg of CBD per dose. At 4500 mg/30 ml, this is about 21 mg, and at 6000 mg/30 ml — about 28 mg per spray. Those starting their journey with CBD should opt for the lowest concentration and gradually increase until they find the right effect — this is the so-called "start low, go slow" principle recommended by experts.

Quality and certificates — look for products with a certificate of analysis (COA) confirming the absence of pesticides, heavy metals, and the correct concentration of CBD. All Reakiro CBD sprays available at u Bucha are tested by independent laboratories. How to avoid price traps when choosing CBD?

Format and application — pure CBD sprays (Reakiro) are intended for daily sublingual supplementation. Alongside them in the category, you will find products supporting natural detoxification after contact with cannabinoids: 420FREE Kleaner 100 ml, DTOX Drink 10 ml and T-Break supplement 30 ml supporting the tolerance break.

Common mistakes when buying CBD spray — the first is buying solely based on price without checking the COA. The second mistake is choosing too high a concentration to start with: jumping to 4500 mg or 6000 mg without prior experience with CBD can make it difficult to find the optimal dosage.

Who should NOT use CBD spray? Individuals taking blood thinners, immunosuppressants, or cytochrome P450 inhibitors should consult a doctor before starting CBD. CBD inhibits CYP450 enzymes responsible for the metabolism of about 60% of prescription medications.

Dosage and use of CBD sprays

Sublingual administration of CBD means that the mucous membrane under the tongue absorbs cannabidiol before it reaches the digestive system. A study published in Frontiers in Pharmacology (2018) confirms that the bioavailability of CBD when taken sublingually is significantly higher than when swallowing a capsule or gummy. Start with 1–2 doses daily and observe the reaction for at least 7 days before making any changes.

The general rule for starting dosage is about 1–6 mg of CBD per 10 kg of body weight daily. For a person weighing 70 kg and using the spray 1000 mg/30 ml this means 2–4 sprays (approximately 9–19 mg CBD).

The timing of use matters. Many users choose the evening — CBD supports relaxation before sleep. When using throughout the day, it's worth splitting the dose: in the morning and evening. The effects of CBD accumulate with regular use for at least 2–4 weeks, so do not judge its effectiveness after the first 2 days.

How to use CBD spray?

1. Shake the bottle — before the first use and after a long break, gently shake the bottle for 5–10 seconds.
2. Position the nozzle under your tongue — open your mouth, lift your tongue, and direct the spray tip to the mucous membrane under your tongue or the inner side of your cheek. Do not aim directly at the throat, as swallowing the product immediately reduces its bioavailability.
3. Press the pump — each full press doses approximately 0.14 ml of the product. With a concentration of 1000 mg/30 ml , this is about 4.7 mg of CBD; start with 1–2 doses and only increase after a few days of stable use.
4. Hold for 60–90 seconds — do not swallow immediately. Hold the product under your tongue for at least 60–90 seconds. This is the most important step: shortening the exposure time significantly reduces the amount of CBD absorbed through the mucous membrane. Pharmacokinetic studies confirm that sublingual retention time directly affects bioavailability.
5. Swallow and wait — after the time has passed, you can swallow the remaining product. The first effects usually appear within 15–30 minutes. Observe the full effect for 60–90 minutes after administration, only then decide on any additional dose.

Safety and contraindications of CBD sprays

CBD is generally well tolerated by healthy adults. European Food Safety Authority (EFSA) is conducting a safety assessment of CBD as a supplement and indicates the need for caution with doses above 70 mg of CBD per day used long-term. Products from u Bucha at starting doses (1–2 sprays daily) are well below this threshold.

The most commonly reported side effects at high doses are dry mouth, transient drowsiness, and mild lowering of blood pressure. CBD inhibits cytochrome CYP450 enzymes responsible for the metabolism of about 60% of medications — if you are taking any prescription medications, be sure to consult the use of CBD with your doctor. It is also worth reading our article on natural methods of coping with stress and choosing CBD, which also discusses safety with regular use.

Pregnancy and breastfeeding — there is insufficient clinical data regarding the safety of CBD in these physiological states. EFSA points to an insufficient amount of data for sensitive populations, therefore pregnant and breastfeeding women should avoid CBD supplementation until further research results are obtained. The use of CBD in children under 18 requires medical consultation.

What do studies say about CBD spray?

Cannabinoids and their routes of administration are one of the most intensively studied topics in pharmacology in recent years. For users of CBD sprays, three areas are key: bioavailability, safety profile, and directions for use.

Sublingual bioavailability — A review published in Frontiers in Pharmacology (Millar et al., 2018) indicates that the bioavailability of CBD after oral administration is only 6–19% due to the first-pass effect through the liver. The sublingual route partially bypasses this effect — CBD absorbed through the mucous membrane goes directly into the bloodstream, which increases the absorbed fraction and shortens the time to the first effect. This explains why sprays and oils work noticeably faster than capsules or gummies.

Pharmacokinetics and duration of action — A 2020 study published in Cannabis and Cannabinoid Research compared the CBD concentration profiles after different routes of administration. Sublingual administration provided detectable CBD concentrations in plasma within minutes, with peak concentration (Cmax) reached after about 30–90 minutes. The half-life was about 1–2 hours with a single oral dose. With daily use, CBD accumulates in fatty tissue, extending the effective duration of action.

Safety profile — EFSA published a technical report (2022), which analyzes the safety of CBD as an ingredient in dietary supplements. At doses up to 70 mg per day in healthy adults, the risk profile is low, and the most common side effects are fatigue, diarrhea, and changes in appetite — usually at doses above 300 mg/day. The doses available in u Bucha sprays (about 4.7–28 mg/spray at 1–2 doses daily) safely fall within the range studied in the scientific literature.

Endocannabinoid regulatory system — CBD acts, among other things, by modulating CB1 and CB2 receptors and the serotonergic system. A review from Frontiers in Pharmacology indicates that CBD does not directly bind to CB1 receptors (which explains the lack of psychoactivity), but modulates their activity allosterically. The entourage effect observed with full spectrum — the synergistic action of cannabinoids, terpenes, and flavonoids — is confirmed in in vitro studies, although clinical evidence is still limited. Therefore, the choice between full and broad spectrum should be based on personal preferences and any professional restrictions, rather than solely on marketing.

Frequently asked questions

Does CBD spray work faster than CBD oil?

The mechanism of action is identical — both products are used sublingually, and the mucous membrane absorbs CBD in a similar way. The difference lies in dosing precision: the spray automatically dispenses a consistent dose with each pump, while the oil requires manual measurement with a dropper. Both formats achieve effects within about 15–30 minutes of sublingual administration, provided the retention time is appropriate.

How much CBD is in one spray?

The standard pump dispenses about 0.14 ml of the product. When a concentration of 1000 mg/30 ml — about 4.7 mg of CBD; when 4500 mg/30 ml — about 21 mg; when 6000 mg/30 ml — about 28 mg per spray. Each manufacturer provides exact values on the label and in the laboratory certificate COA.

What is the difference between broad spectrum and full spectrum in spray?

Broad spectrum contains CBD and other cannabinoids, but THC is removed to an undetectable level. Full spectrum retains the natural spectrum — along with THC to 0.2% according to EU law. The entourage effect is stronger with full spectrum, but sensitive individuals or those avoiding THC for professional reasons should choose broad spectrum.

How long does the effect of CBD spray last?

The duration of action depends on the concentration and individual metabolism. Typically, the effect of sublingual administration lasts for 4–6 hours. Pharmacokinetic studies of CBD indicate that the half-life for sublingual administration is about 1–2 hours with a single dose, but with regular use, it extends.

Is CBD spray legal in Poland?

Yes — CBD sprays from Reakiro available at u Bucha contain CBD from legally cultivated industrial hemp strains and meet EU legal requirements regarding THC content (below 0.2% THC). They are dietary supplements, not medicines. Legality is confirmed by the COA certificate of each product.

Can CBD spray be used daily?

Yes — daily CBD supplementation is common and used in most clinical studies. Studies lasting 4–8 weeks with daily doses of 15–25 mg of CBD did not show serious side effects in healthy adults. It is recommended to use it at a consistent time and the method start low, go slow when selecting the dose.

What is 420FREE Kleaner Spray and how does it work?

420FREE Kleaner this is an oral spray with natural plant extracts — garlic, fennel, wormwood, beetroot, and caper. It is a dietary supplement, not a medicine. The formula is alcohol-free and fully natural. Available in a capacity of 100 ml in a refreshing mint flavor.
