The Jack Herer high is happy, bubbly, euphoric, energizing and creative in combination with a wonderfully relaxing, yet not sedated body buzz. The Jack Herer high is versatile and can be a good choice for a wake and bake before for a day of errands or settling in on the couch for the evening. The high provides an excellent balance between the cerebral and physical effects, leaving the users deeply relaxed but attentive and social.

The buds are a bright lime green, covered in a blanket of trichomes and rust colored hairs. Jack Herer buds are so thickly smothered with clear trichomes that they appear sugar-frosted or sparkling with dew-drops. The aroma can be described as spicy pine and citrus with a peppered punch. The Jack Herer smoke is soft and tastes similar to the smell, leaving the palate with a pleasant spicy pepper aftertaste.

Jack Herer’s combination of both Sativa and indica effects make it a sought after strain for both adult-use and medicinal users. The pain and stress relieving body effects are accompanied by an uplifting head high, for those seeking daytime pain relief from a cannabis strain. These effects can also be beneficial for those with mood debilitating disorders such as depression and anxiety.

Jack Herer Effects

Searching for an uplifting yet potent psychoactive buzz? This cannabis strain has the reputation of inspiring a stimulating and thoughtful mental experience. Potent, this plant routinely contains between 16 and 20 percent THC, the primary psychoactive molecule in the cannabis plant.  

As a high-THC cultivar, consumers can expect changes in perception and insight after participating in Jack Herer. In particular, THC can temporarily cause feelings of happiness, relaxation, and euphoria. It can also change your perception of time, which many consumers find helpful in enjoying the present moment. While this particular cultivar isn’t commonly known to produce sedation, research on THC suggests that it stimulates the production of melatonin. Melatonin is a neurotransmitter that helps control the body’s internal clock, inspiring feelings of sleepiness at nighttime.

However, high levels of THC can also have negative side effects. It is not uncommon for those with low tolerance to the terrain to experience a raging heartbeat. THC can also cause anxiety and paranoia in some consumers, especially if it is taken too much. However, Jack Herer offers more than just THC. To get a deeper insight into the experience that this strain offers, current thought suggests that it is important to follow your nose.

The History of Jack Herer

Jack Herer starts with a well-known sativa called Haze and is then crossed with Shiva Skunk and Northern Lights # 5 to provide strong indica traits and a real layer of sticky white trichomes and resins. Jack Herer is a child of the mid-1990s.  It was bred in the Netherlands by renowned cultivator Sensi Seeds. The purpose was to create a highly medical burden by combining Haze’s clear-headed Sativa stimulation with the overwhelming amount of Shiva Skunk and Northern Lights # 5 resins. So it was possible to create a hybrid that has won numerous awards and was strongly prescribed by Dutch doctors and is very popular with recreational users. It quickly spread to weed hotspots around the world and eventually to personal growers who produced their own unique recordings of Jack Herer. With the end of weed prohibition in some states in the US, with medical use being the most accepted use, Jack Herer has emerged as a prime candidate for doctor recommendations as well as recreational use.


More on Jack Herer marijuana strain

Jack Herer is perhaps one of the most typical Sativa strain of all time. Named after the “Emperor of Hemp,” this optimistic flower pays tribute to the late Jack Herer, a popular cannabis activist, and author. Jack Herer is a man to remember.

Herer sometimes referred to as the “father” of the legal cannabis movement, began in 1973, along with his activist Ed Adair, who campaigned with him for the legalization of cannabis. He published 1985 The Emperor Wears No Clothes, one of the most popular and often cited historical studies of the cannabis factory. The book has been printed every year since its publication and now appears in its twelfth edition.

Herer is an apostle for the reunification of hemp and ordinary life, and he worked diligently to educate the public about the myriad medical, social and environmental benefits of hemp. He campaigned until his death in 2010 for legalization. The Jack Herer cannabis strain was created in the 1990s as a commemoration to Herer’s life work. The invigorating flower was bred by Sensi Seeds in the Netherlands and contains a complex mix of Haze, Northern Lights # 5 and Shiva Skunk. No wonder the herb won many cannabis cups in its day. Now, Jack Herer’s relatives and offshoots are more likely to be found on the shelves of pharmacies. Nevertheless, this stunning and resinous strain is one of the most popular and well-known sativa plants in contemporary history.


The Flower

Jack Herer has won seven-count them, SEVEN — first-place wins at the High Times Cannabis Cup. That should be no surprise. “The best Jack Herer borrows sharp lemon candy, fresh pine and light clove notes from its Northern Lights and Shiva Skunk lineage while adding buttery vanilla undertones from its Haze background. This was surprisingly complex for a ’90s creation like the weed version of’ The X-Files’. In addition, it will have a sativa-like appearance with long branches and a squared structure. So look for a Christmas tree shape as opposed to a rounder, bulbous structure.

A well-balanced hybrid, Jack Herer generally tends to easily sativa at 55% to 45% Indica. THC can be up to the age of 20 in high teens, along with a considerable amount of CBG (anti-inflammatory and antioxidant). There is little CBD content – not enough to write about. But that’s fine: the strain makes up for it by producing a striking head-high that is cerebral and great to “shit”

When Sensi Seeds created this strain, they not only wanted to honor this legendary man but also wanted to make a 50% Haze cross that maintained the characteristics of the best sativas but did not require a painful time (6 months) to flower. They did a solid job! While Herer’s ancestry has been somewhat secretive, most believe it is a menage-a-trois of three strong strains: Haze (Sativa); Skunk #1 (a Sativa-dominant hybrid); and, Northern Lights #5, (an indica-dominant hybrid). This three-way hybrid is a great contender for both recreational and medicinal users.
