What is J1?

J1 is a hybrid-leaning sativa strain (Skunk #1 x Jack Herer) with THC levels of 18-24%. It features a Terpinolene-dominant terpene profile and is known for relaxed and happy. Best used during the evening.

About J1 Strain

J1 is a sativa-dominant hybrid cannabis strain created by crossing Skunk #1 x Jack Herer. Testing at 18-24% THC, J1 offers moderate to strong potency suitable for regular cannabis consumers.

Users of J1 commonly report feeling relaxed, happy, euphoric. The experience typically begins with an uplifting cerebral rush that sparks creativity and mental clarity. As the high develops, many users find themselves more talkative and socially engaged. Best enjoyed in the evening, this strain helps transition from the day's activities into a more relaxed state.

Medical cannabis patients frequently turn to J1 for relief from stress, anxiety, chronic pain. Terpinolene's presence adds uplifting qualities while potentially offering antioxidant and sedative properties at higher doses.

Due to its moderate-to-high potency, J1 is best suited for experienced cannabis consumers. New users should approach with caution, starting with a very small dose and waiting to assess effects before consuming more. Common side effects may include dry mouth, dry eyes. Staying well-hydrated and having snacks on hand can help minimize discomfort.

The aroma of J1 is characterized by earthy, sweet, pungent notes that create a distinctive sensory profile. On the palate, expect earthy, sweet, herbal flavors that develop throughout each session. The terpinolene-dominant terpene profile is largely responsible for these aromatic and flavor characteristics, contributing to the entourage effect that shapes the overall experience.
