The calm disposable vape pen by dosist has a 10 1 CBD to THC ratio. It harnesses the properties of CBD and pairs them with naturally occurring terpenes like beta-caryophyllene (also found in black pepper, cloves and balsam) and limonene (present in citrus fruits and juniper). The vaporization elements reach precise temperatures and deliver a pull quickly and accurately, while consistency is achieved through optimized temperature, airflow and time controls. To use, inhale at a normal, consistent rate, and the vaporizer will shut off automatically after 3 seconds. A slight vibration will occur when 2.25 mg has been released. This pen is available in two sizes 0.185 g (50 pulls) and 0.5 g (200 pulls).
