Yes, there are CBD oil cartridges tailored for discreet vaping. These cartridges are designed to produce less vapor and have a more muted aroma than their THC-rich counterparts. Opting for a higher-quality oil vape pen can also make a difference, as they often allow for better temperature control and smoother vapor production. Additionally, CBD doesn't have the strong, recognizable smell that THC has, making it ideal for those who want to vape without drawing much attention.
