If you're a cannabis fan who cares about her long-term health, you should be vaping instead of smoking. But these days, different strains and brands can be so strong that it's hard to know what you're getting (or to properly microdose). That's where this new innovative vape pen comes in: The Dosist ($40 for the 50-dose version, $100 for 200-dose pens) comes loaded with one of six custom formulas depending on your mood — bliss, sleep, calm, relief, arouse, and passion — and measures out a precise 2.25-milligram dose with each use. That means that with each hit, you know exactly how much you're getting, and won't need to overdo it.
