Juuls use a silica wick which, while possible to absorb something as thick as Vit A the vaporization process would happen too quickly for the pod to perform properly. You'd have to wait 10+ minutes between puffs and the vapor production would suffer greatly. You would immediately know something was wrong. Concentrate cartridges use a ceramic stone with a heating element inside or encased. This ceramic greatly reduces the flow rate and allows slower vaporization of the concentrate. I ran a vape shop for years I am more than happy to discuss safety of vaping but won't participate in whataboutism.
