I've noticed this personally, they're from a dispensary. Sometimes they just never work, I'll switch to another pen, it works, I switch back to the one that didn't and it works, but in general I feel like there's a difference in potency throughout. This Tahoe OG I have which is like a pure stone has been giving me euphoria instead lately, there never was really much of that before, it's less than half vaped.
