MAC n Jack strain guide
MAC n Jack is a hybrid of MAC 1 and Jack Herer from Ethos Genetics. It pairs MAC's creamy citrus with Jack's piney, spicy side, and people know it for a sharp lemon and pine smell and a potent, creative feel that can turn heavy. It's a strong one, so it's better suited to people who already know their limits.
Where does MAC n Jack come from?
One strain database and Grow Diaries both credit MAC n Jack to Ethos Genetics, bred from MAC 1 and the 1994 cut of Jack Herer. Ethos sells it as feminized seed under the name MAC N' Jack R1. Another database lists the same two parents.
MAC 1 comes from the breeder Capulator and is known for its creamy citrus funk, while Jack Herer is the famous piney, spicy strain from the 1990s. You may also see the cross written as MAC and Jack or Mac Jack, and a few other producers have used similar names, so not every product is necessarily the Ethos version.
What does MAC n Jack smell and taste like?
Lemon comes first: sharp and sour, often described as old-school or landrace-style citrus. Behind it sit pine and wood, and some describe incense, sandalwood, nutty or earthy notes. The taste follows, with sour citrus up front and a woody pine finish.
We couldn't find published terpene results for MAC n Jack, so we haven't listed any. The pine and lemon notes suggest it takes after Jack Herer, but your product's label is the only reliable guide to what's actually in it.
MAC n Jack effects: what people report
Reports split a little, which fits a cross of a creamy hybrid and a classic sativa-leaning strain. Some people describe a focused, creative and uplifted start that suits the daytime. Others talk mostly about a strong, calming body feel, and at higher amounts it can leave people stuck to the couch or a bit foggy.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth is common, and one reviewer mentioned feeling anxious.
How strong is MAC n Jack?
MAC n Jack is a very high-THC strain. Breeder and database listings put it around 25% to 30% THC, and grow journals have reported batches near the top of that range. CBD is low, though one listing shows other minor cannabinoids like CBG.
This is not a beginner strain. Start with a small amount and give it plenty of time before having more. The THC on your label matters more than the strain's range, and our guide to THCA vs THC explains why you'll often see two numbers.
Buying MAC n Jack in Canada
Because similar names float around, look for MAC 1 and Jack Herer as the listed parents, or Ethos Genetics as the breeder, if you want this exact cross.
You might find it as dried flower, pre-rolls or concentrates. Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of its lemon and pine.
MAC n Jack vs MAC 1
MAC 1 is one of MAC n Jack's parents. MAC 1 is known for a creamy citrus and pine funk and a clear, balanced feel. MAC n Jack keeps the citrus but trades some of that creaminess for Jack Herer's sharper pine, wood and spice, and many people find it heavier at higher amounts. If you like smooth, creamy citrus, start with MAC 1. If you'd like more pine and bite, try MAC n Jack.
