J1 Strain

J1, sometimes known as Jack 1, is a relatively rare and special strain of marijuana that is much sought after by people who are interested in securing high end and collector’s edition cannabis. J1 is a hybrid and a cross between the famous Jack Herer and the almost equally famous Skunk #1. J1 is slightly Sativa dominant at 60% and is recommended for the morning as opposed to evening use, as it can be somewhat energizing. The high is unique, a clear-headed yet energizing stone that has well-balanced Sativa and Indica effects. J1 has a strong but not unpleasant smell of citrus that tends to travel far in both the growing stage and when ground up. While pleasant, if you have family or flatmates who are not smokers then it is best to consume this strain outside. The taste of this strain is similar to the smell, a sweet taste of orange. J1 is known to be a cerebral strain, and users will immediately note the head effects. It will induce clarity, focus, and euphoria, bringing people into the zone. It is useful for creative individuals who need inspiration and stimulation and is perfect for morning use. It will definitely make users happy, uplifted and creative, and is not suitable for evening use. It is not at all effective for the treatment of insomnia and has the opposite effect, despite being only mildly Sativa dominant. The flowers are emerald green and frosty with a sweet aroma resembling the unmistakable Jack Herer pungency. This strain’s seemingly only flaw is the top-shelf price that tends to come with its exceptional quality. It is also a little difficult to grow this strain well.

Why do Patients Use J1?

J1 is has a wide variety of medical benefits, and it would be nice to see it distributed more widely on the medical market. It can be found in dispensaries in California, Washington, and Oregon. J1 is a supreme strain for those suffering from anxiety and depression. All negativity will melt away with the wonderful cerebral uplift that the strain provides. It is also highly effective for the treatment of ADHD, ADD, PTSD, and Bi-Polar. This strain is medical marijuana gold.

However, the strain is not for first-time medical marijuana users as it is very potent, with THC levels ranging between 20-24%. The only areas where J1 does not excel as a medical strain are in the treatment of chronic pain and for insomnia.
