Where does Blue Alien come from?

Blue Alien is a cross of Blueberry, the classic berry-scented indica, and Alien Kush, a kush line with a heavier, earthier side. Both main listings agree on that pairing.

Who first made the cross isn't documented, and neither listing names a breeder. It's a fairly low-profile strain compared with its parents.

What does Blue Alien smell and taste like?

Blueberry is the headline: sweet, ripe berry with a candy-like edge. Some people also pick up earthy, fruity or faint diesel notes, and a few mention something floral on the exhale.

Published terpene results list myrcene first, then limonene and pinene. Myrcene gives the soft, earthy fruit, limonene a touch of brightness and pinene a fresh pine note.

Blue Alien effects: what people report

People usually describe Blue Alien as relaxing and sleepy, with a euphoric, sometimes giggly start. Couch-lock comes up often in reviews, so most people treat it as an evening strain rather than something for a busy afternoon.

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

How strong is Blue Alien?

Listings put Blue Alien at around 17% to 21% THC, which is moderate to fairly strong for an indica. A couple of reviewers report batches in the mid 20s, so some cuts may run higher. CBD is listed as close to zero.

Start small, especially if you're new to heavier indicas, and give it time before having more. The THC and CBD numbers on your label matter more than the strain name.

Buying Blue Alien in Canada

Blue Alien is less common than other blueberry strains, so check the label to make sure you're getting this Blueberry and Alien Kush cross and not a similarly named berry strain.

If you find it, look for dried flower or pre-rolls, and check the THC and CBD numbers and the packaging date. Fresher flower keeps more of that berry candy smell.

Blue Alien vs Alien Kush

Alien Kush is one of Blue Alien's parents. Alien Kush leans earthy and kushy, with a classic hash-and-pine profile, while Blue Alien swaps much of that for sweet blueberry and candy notes from its Blueberry side. Both are known for a relaxed, heavy finish. If you like a traditional kush smell, Alien Kush fits. If you want the same calm feel with more fruit, try Blue Alien.

  • Blueberry: the other parent, with the same sweet berry smell.
  • Blueberry Kush: another berry and kush pairing with a heavy, relaxed feel.
