Background: Given limited extant research, we assessed the use of portable, battery-powered cannabis vaporizers by adult e-cigarette users.
Methods: 522 adult vapers completed an online survey. Demographics; lifetime and past-month cannabis vaporization via e-cigarettes/vape-pens; preferences for hash oil, D-9-tetrahydrocannabinol (THC) wax, or dried buds; and cannabis vaporization beliefs and motives were examined.
