Nightmare Cookies Strain

The Nightmare Cookies marijuana strain owes its name from the parent plants it is bred from. These include White Nightmare, a stove-dominant hybrid, and Girl Scout Cookies (AKA GSC), an indica-dominant hybrid.

The result is a nice, sativa-dominant hybrid. There’s enough THC present to produce a medium high, and has a pleasant taste and aroma to enjoy as it soothes and relaxes you.

In this article, we’re going to be talking about the strains’ history, including its genetics and origin, and it’s appearance, taste, and aroma. We will also be talking about the presence of cannabinoids and terpenes within, and about its various side effects and medical benefits.

This is then followed by a quick review, before we go on to talk about growing information, such as yield, seeds, and flowering time. Then, we’ll wrap up with a brief conclusion.

Please feel free to scroll ahead to any area of interest to you.

Strain History

Now, this is quite a convoluted breed of marijuana. It is not at all pure, but is a hybrid of two other hybrid marijuana plants. Let’s break it down for you.


We mentioned this in our introduction, but it bears repeating here. The Nightmare Cookies marijuana strain owes its name from the parent plants it is bred from…

These include White Nightmare, a stove-dominant hybrid, and Girl Scout Cookies (AKA GSC), an indica-dominant hybrid.

For those who are interested, White Nightmare is the child of Blue Dream, yet another hybrid. While the Girl Scout Cookies marijuana strain is the child of OG Kush and F1 Durb.

(In the interest of brevity, we won’t go back any further than that.)

It may also interest you to know that the Nightmare Cookies strain can be bred with the Mint Chocolate Chip marijuana strain to produce the hybrid strain known as Devil Cookies.


The precise origin of the nightmare cookie strain still remains a little muddled. However, the origin of its parent, the Girl Scout Cookies marijuana strain is known – in fact, all cookie strains originated in the San Francisco / Bay area of the USA.

Strain Appearance

The Nightmare Cookies marijuana strain is quite modest in size and colorful in appearance. It features bright orange pistils, and deep, frosty-looking purple hues that could almost pass for silver.

Strain Flavor

One of the great things about the Nightmare Cookies marijuana strain is its seductive, sweet flavor. Don’t get me wrong it does still have that more common earthy tone to it, but this is in the background, and it’s the sweetness that overpowers it.

Strain Aroma

The top aroma that hits you with the Nightmare Cookies strain is that reminiscent of pine tree sap. This is combined with a little earthiness too, but the dominant scent is one of sweetness and berries.

This is thanks to the terpenes present, which we will be covering in more detail shortly.

Strain Cannabinoids

For those who don’t already know, cannabinoids are the name given to compounds found in cannabis plants that will bind to cannabinoid receptors on nerve cells in the brain.

These cannabinoid compounds can be either psychoactive or non-psychoactive. If a cannabinoid is psychoactive, this means that it will have an effect on the mind.

One of the more common cannabinoids present in marijuana plants is THC, which is short form for Tetrahydrocannabinol, and this is the cannabinoid most often associated with getting high.

The Nightmare Cookies strain is believed to contain at least 17% of THC. Although, there are some who say that there’s as much as 22.75% of THC present.

There is also another cannabinoid present known as CBD, which is the short form for cannabidiol. But this will not give you high, and is only present in very low levels in this strain. Specifically, between 0.46 and 0.78 %.

There may also be other cannabinoids present in this strain at similar levels to the CBD.

Strain Terpenes

It is the terpenes with the Nightmare Cookies marijuana strain that are responsible for the strain’s overall taste and aroma.

The Nightmare Cookies marijuana strain has a very broad terpene profile, featuring a whopping 12 different terpenes altogether.

The most dominant terpene in the mix for the Nightmare Cookies strain is pinene. And with its pine forest aroma, it is responsible for exerting that calming pine sap scent we made mention of earlier.

The other more abundant terpenes present include myrcene, which gives off a more herbal, earthy scent, and is one of the more common terpenes present across all marijuana plants.

And this is closely followed by caryophyllene, which is responsible for giving off a peppery scent.

Strain Side Effects

Unfortunately, there have been several side effects reported for the Nightmare Cookies marijuana strain.

The predominant side effects are psychological ones, with almost 50% of users reporting feeling anxious.

This is closely followed by insomnia and trouble getting off to sleep.

However, some of the more common side effects of taking marijuana aren’t as strongly present in this strain as they are on other strains.

For example, only a mere 14 % of users have reported experiencing a dry mouth. While even less have reported experiencing dry eyes.

Medical Benefits

We are pleased to report, however, that various medical benefits have been brought to our attention…

The predominant medical benefits derived from the Nightmare Cookies cannabis strain are psychological ones. This should not be surprising, given the relatively high level of the psychoactive cannabinoid THC (AKA Tetrahydrocannabinol).

More specifically, it has been found to be very effective at treating depression, and at reducing the user’s stress levels.

The Nightmare Cookies cannabis strain has also proved to be very effective at treating a lack of appetite.

And finally, we can report that 44% of users have reported a reduction in headaches.

Strain Review

The Nightmare Cookies cannabis strain is quite typical in its effects.

At first, you’re met with the aroma, which is distinctly marijuana, but also comes combined with a scent reminiscent of pine sap, and an underlying sweetness.

And this distinctive underlying sweetness carries through to the taste as well.

It has a medium to high level of the psychoactive compound THC present, and because of this, partakers get to enjoy a nice high. Approximately 92% of users have reported feeling euphoric after partaking, while 91% have reported feeling happy, and almost as many, 89%, have reported feeling relaxed.

But that’s not all. Other reports have included the likes of feeling uplifted and focused, and a lift from their depression. And medical benefits such as this are what makes it all worthwhile.

Moreover, the Nightmare Cookies marijuana strain enables users to treat their stress and depression without having to endure more common side effects such as a dry mouth and dry eyes.

(These side effects can occur, though they have been reported at a far lower rate compared to similar alternative marijuana strains.)

It has also been known to have an effect on the user’s appetite.

Strain Grow Info

The Nightmare Cookies marijuana strain is moderately difficult to grow, so perhaps not well suited for beginner growers.

You can grow it either indoors or outdoors, and it gives quite a good yield (more on that later).

When grown indoors it can grow to a height of 60 to 80, but outdoors it will grow even taller to 90 plus.

Strain Seeds

The seeds to grow your very own Nightmare Cookies strain are readily available online. Or you could go old school and breed them via crossing their two parents, White Nightmare and Girl Scout Cookies.

Strain Flowering Time

The flowering time for the Nightmare Cookies strain comes in at 56 to 63 days. Or, in other words, 8 to 9 weeks. Harvest time is a little longer, coming in at 71 days.

Strain Yield

The Nightmare Cookies strain can provide a very generous yield. When grown indoors, you can expect to harvest 400 grams per square meter (or in other words, 1 to 2 ounces).

And when grown outdoors, you can achieve an even better yield, coming in at approximately 550 grams per plant, which is about 15 to 20 ounces per plant.

Wrap Up

Those who are thinking of partaking of the Nightmare Cookies strain should not be put off by the name. Sure it can produce anxiety in some, but it does not induce paranoia, hallucinations or nightmares.

In fact, it can be rather effective at treating psychological ailments such as stress and depression. This is achieved partly through its mellowing effect and partly through a mild euphoria.

You could even argue that it’s a better strain to take compared to many others, due to the improved sweeter taste, and the reduced side effects of dry mouth and dry eyes.

It’s moderately difficult to grow and cultivate, however, so we don’t tend to recommend it for beginner growers.
