Vape pens have become ubiquitous in states that have legalized cannabis. And for good reason: Vape pens are so easy to use, discreet, come in an assortment of styles and the cartridges are easy to replace. The vape pen itself is essentially a battery and the consumer purchases oil cartridges that come in a wide variety of potency and flavors. With vape pens, consumers can easily modulate their dose by trying a variety of cartridge with a wide range of CBD-THC ratios. For example, you could begin your symptom relief with a 20:1 CBD-THC product and slowly work your way to a ratio that suits you best. Many customers will vape a CBD-rich cartridge during the day and switch to a cartridge higher in THC in the evening.

Handy, discreet and perfect for the on-the-go person. *Vape Cartridges (Require External Battery)
