This review is for an absolutely stunning and, by all rights, flawless grown and cured version of this strain fresh from one of the most expensive, highest-rated dispensaries in LA. Exceptionally vibrant, clear vision but with narrow, specific focus. Emotional state is on point for Jacks; light, uplifting, and euphoric. However, and also true for Jacks, is its emotional instability. Feelings are a bit edgy and fragile - not stable and would be reason to pause about doing in potentially stressful environments. I’m noticing more how much Jack’s physical drain detracts. It just makes your body feel...tired. Lethargic. Not “irresistible couch lock”, but more tense than relaxed. On the flip side, that also contributes to a sense of fun and thrill. Uncommon for a Jack is the ease of the come on. Most of the time there's a bit of a racy rush at the beginning, but this one didn't have that difficulty at all. Music sounds good! Smooth and pleasurably accented. The high continues impressively for a nice and long while with mostly a tampening of the brain and continual, chilled out euphoria. Instead of crashing, the physical drain gradually lifts off, maintaining productivity. So, not all negative...but strong pros/cons to consider.
