Sirius Black Strain

Sirius Black is an indica-dominant hybrid sitting at 20 to 26% THC. It hits hard and leans sedative – this is an evening strain. Named after the brightest star in Canis Major, one of the darkest points in the night sky, it carries that weight in the experience too. Myrcene leads the terpene profile, pulling the aroma toward ripe grape and pushing the body toward the couch. It belongs in the same conversation as the heavier-hitting cannabis strains out there.

Effects

Sirius Black tends to open with a warm euphoric lift that many users describe as settling rather than stimulating. Within 15 to 30 minutes, that mental ease typically gives way to a full-body heaviness. Effects may last two to four hours depending on tolerance. At higher doses, deep sedation is common, making this cultivar one many consumers reserve for late-night use. Users who enjoy similarly relaxing Granddaddy Purple or Northern Lights often find Sirius Black a natural next step. If you enjoy exploring potent flower, the flower and prerolls section has options worth browsing.

Negative effects

Dry mouth and dry eyes are the most commonly reported downsides – staying hydrated helps significantly. Higher doses can bring dizziness, especially if you haven’t spent much time with high-THC indicas. Start low, wait, then decide if you need more.

Help with

Sirius Black is often chosen by people looking for evening stress relief. Many users report that the heavy body sensation helps them quiet a racing mind before bed, and it appears frequently in conversations about sleep support. These are user-reported experiences. This is not medical advice – tolerance, dose, and personal chemistry all shape what you actually feel.

Flavours

Grape and berry hit first. The exhale turns earthy – closer to damp soil than fresh fruit. There’s a subtle sweetness at the finish, but this isn’t a bright or citrus-forward smoke. The flavour is full and slow, which fits the rest of the experience.

Terpenes

Myrcene (green) is the dominant force here, the terpene most closely associated with earthy aroma and the couch-lock sensation many indica lovers seek. It contributes the grape and berry depth in the flavour profile and amplifies the sedative quality of the high. Caryophyllene (red) adds a faint spice and is the only terpene known to interact directly with the body’s endocannabinoid receptors, potentially adding to the physical ease users report. Limonene (yellow) shows up quietly – just enough citrus to keep the aroma from going completely flat, without pulling the profile in a different direction.

THC level

At 20 to 26% THC, this isn’t a beginner strain. If you’re new, start with one small dose and stop there. Intermediate consumers who know high-THC indicas will find it manageable. Experienced users can work into the full range – but even then, there’s no prize for rushing it.

CBD level

CBD sits at 1% or below, so it contributes little measurable modulation to the experience. The overall character here is driven almost entirely by THC and the terpene combination rather than any meaningful cannabinoid balance.

Frequently asked questions

What are the effects of Sirius Black?

Sirius Black typically produces an initial wave of euphoria followed by deep physical relaxation. Many users report feeling calm and sleepy as the experience progresses. Effects generally last two to four hours. Because of its sedative lean, most consumers use it in the evening rather than during daytime hours.

Is Sirius Black indica or sativa?

Sirius Black is an indica-dominant hybrid. Its effects skew heavily toward the physical and sedative side of the spectrum rather than the cerebral or energetic. If you’re looking for daytime focus and creativity, this cultivar won’t serve you well. It’s a rest strain, full stop.

How strong is Sirius Black?

20 to 26% THC puts it firmly in potent territory. Newer consumers should start with a lower-THC strain first. If you do try it, one small dose and a long wait is the right approach – experienced or not.

What terpenes does Sirius Black have?

The dominant terpenes in Sirius Black are Myrcene, Caryophyllene, and Limonene. Myrcene drives the earthy, grape-heavy aroma and contributes to the sedative quality. Caryophyllene adds a subtle spice and may support the body-relaxation effect. Limonene introduces a faint citrus note that keeps the profile from feeling too heavy.
