In Review: The Ace of Spades Vape from O.pen will put you at ease no matter what’s on your plate. While it was designed to provide just the lullaby you need to hit the hay, it will also loosen you up with notes of lemon and an amiable high that can help you push through a workout or shine in social situations. One of O.pen’s Daily Strains, you can rest assured that this was scientifically formulated to achieve consistent effects and a fantastic flavor profile. So stock up, and get ready to power down.

The box for this O.pen cartridge says, “Sleepy.” Score: I love to sleep! I try to get at least eight hours each night (I know, this is a luxury for many) and become a grumpy bear when I’m tired. Unfortunately, I’m also a light sleeper. The gentle rustle of my partner reaching for their phone in the morning wakes me up, regardless of how silent they think they’re being. Even more unfortunately, I’m also an occasional insomniac, especially when I’m stressed.

Fortunately, there’s weed for this.

I decided to take the Ace of Spades cartridge at its word and employ it as a sleep aid on a few nights when I had a lot on my mind. Each time, I had the same strange experience. I’d screw on the cartridge to the O.pen battery, heat it up, take a smooth, blueberry-tasting hit or two in bed, and experience a gradual and pleasant inability to do anything but sleep. I’d fall asleep fast and sleep deeply for a while. Then I’d wake up completely alert…at 4 a.m.

I figured it was the high wearing off, and while it wasn’t too difficult to get back to sleep, I was starting to side-eye the Ace of Spades. But then I cracked the code. I’m not much of a gearhead when it comes to weed, and the O.pen battery is a touch more sophisticated than my ten-year-old, flower-only vape, with several modes for heating the concentrate.

“I felt my mind shut off with a nearly audible click, and slept soundly all night long.”

Once I clicked the end twice to bump up the voltage from low to medium, I took a puff, felt my mind shut off with a nearly audible click, and slept soundly all night long. Success! As a lightweight, I’ve avoided the ‘dab’ mode, accessed by cycling the pen through until its lights glow blue, and then holding the button down to inhale. But I’m willing to bet it'd knock out even the most seasoned stoner.

A note on the O.pen experience: others’ mileage may vary, but I’ve found this setup to be relatively smooth and easy to draw on. I have asthma, and even a perfectly functioning pen can feel harsh in my throat and chest. I’ve accidentally pan-seared my lungs by drawing on a cloggy cartridge, with the resulting miserable burning sensation lasting hours.

But the O.pen is smooth, and I don’t end up with a sore throat or tight chest. The company is part of a corporate cannabis conglomerate, which I have mixed feelings about. But a benefit of their parent company’s ample resources is that they have tons of money and people to ensure they’re selling good quality products. And because they operate nationally, they’re under scrutiny by multiple states to meet their safety standards.

Lungs intact, I brought Ace of Spades out of bed and into the world on a mild afternoon, taking a few hits before I went on a short city run around a scenic pond. This outing was for science—I was curious if I would feel compelled to lie down and nap right on the trail, zonked out in my sneakers. But instead, I became a running machine. My mind remained totally in the present, focused on one foot in front of the other.

“When I returned home, I enjoyed a pleasant drifty feeling that lasted a few hours.”

I smiled at folks out enjoying the weather. I vibed to my music. I didn’t even contemplate when I might stop, a question that usually preoccupies me entirely when I exercise. No aches, no pains, just my feet on the ground and the light playing over the surface of the pond. When I returned home, I enjoyed a pleasant drifty feeling that lasted a few hours. And when the high wore off, I didn’t feel like I’d gone too hard, even though RunKeeper logged my time as faster than usual.

Later, the cartridge delivered the same experience at a dance class: pure, in-the-moment presence and energy that carried me through a strenuous practice. I felt enough mental clarity to remember complicated choreography, and the physical ability to keep pushing past where I might have felt tired without it.

After practice, I enjoyed that mellow drifty feeling again as I caught up on small talk with my fellow dancers. Sometimes, indica-dominant strains make me too paranoid to want to chit chat with folks who don’t know I’m high. Perhaps you know the feeling: what if I say something weird? But the Ace of Spades allowed me the presence of mind and social aptitude to be a decent—and very smiley—conversationalist.

I can’t explain how the same concentrate can both knock me out and pump me up. Maybe it’s the CBN in the formula. Maybe it’s the Motorhead song that starts playing in my head each time I bust out the cartridge. But I’m not going to question this gift too much. The next time my workout energy is flagging, I’ll turn to O.pen’s Ace of Spades to keep my head in the game. And the next time I can’t sleep, I’ll use it to keep my head on the pillow.

Apparently, the only cartridge I need for any activity is the Ace of Spades.
