Blue Crack strain guide

3 min read · Updated October 14, 2026 · WeedDB editors

Blue Crack is a hybrid of Blue Dream and Green Crack, two of the best-known daytime strains around. People know it for a sweet blueberry smell and a focused, energetic feel that's usually called smoother than Green Crack on its own.

Where does Blue Crack come from?

Blue Crack is a cross of Blue Dream, a sweet berry hybrid, and Green Crack, a punchy sativa-leaning strain known for its energy. Strain databases agree on that pairing, but no breeder or release date is well documented.

Sources disagree a little on the balance. Some call it sativa-leaning, which fits its reputation, while others list it as an even 50/50 hybrid.

What does Blue Crack smell and taste like?

Blue Crack smells sweet and smooth, with blueberry front and centre. That berry side comes from Blue Dream, and it carries through to the taste.

Pinene is the terpene most often reported at the top, followed by myrcene and terpinolene. Pinene brings a fresh, piney lift, myrcene a softer, earthy side and terpinolene a light fruity note. The flavour is usually sweet berry from start to finish.

Blue Crack effects: what people report

People most often describe Blue Crack as focused, energetic and euphoric, with a clear head rather than a heavy body feel. A common theme in reviews is that Blue Dream softens Green Crack's rush, so it feels stimulating without being as racy. That's why many people save it for the daytime.

These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth and dry eyes are the most common complaints, and some people mention a headache or feeling hungry.

How strong is Blue Crack?

Blue Crack is usually a mid to high-THC strain. Listings put it around 18% to 24% THC, with little or no CBD.

If you're new to it, start with a small amount and give it time before having more. The THC and CBD numbers on your label matter more than the strain name, so check the batch in your hand.

Buying Blue Crack in Canada

Blue Crack is a less common name than either of its parents, so read the label to make sure you're getting the cross and not Blue Dream or Green Crack on their own.

Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of that blueberry smell.

Blue Crack vs Green Crack

Green Crack is one of its parents, and the two share a focused, energetic reputation. The jar is where they split: Green Crack smells of sweet mango and citrus, while Blue Crack leans blueberry. Green Crack is known for a sharper, more intense rush, and Blue Crack is usually called smoother thanks to its Blue Dream side. If you want the full burst of energy, Green Crack is the classic. If you'd like something a bit gentler with a berry smell, try Blue Crack.

  • Jack Herer: another clear-headed daytime favourite with a piney edge.

How long does a high last? Smoked, vaped and ediblesHealth Canada says that after smoking or vaping you could feel effects for 2 to 4 hours, and after eating or drinking cannabis for 4 to 8 hours. Edibles also start later: within 30 minutes to 2 hours, compared with seconds or minutes when inhaled.Kief and trichomes: what they are and what to do with kiefTrichomes are the tiny resin glands on cannabis flower that hold most of its cannabinoids and terpenes, and kief is the powder of trichomes that falls off the flower, often collecting at the bottom of a grinder. Pressed together, kief becomes hash. Both are concentrated, so Health Canada advises new or occasional users to avoid them.How to read a cannabis label in CanadaEvery legal cannabis product in Canada has to show its Total THC and Total CBD, the red THC symbol, a yellow health warning, a lot number, a packaging date and an excise stamp for your province. Total THC is the number to compare, and it's shown in mg/g for flower and in mg per piece and per package for edibles.
