Absolutely. You have to be so careful with the extraction methods and diluent agents when it comes to vaping concentrates (that includes regulated vape carts--not just black market carts).

[Cannabis] extracts are not diluted in propylene glycol or glycerol like nicotine due to their hydrophobic properties. Instead, various forms of oils including vegetable oils, terpenes, and tocopheryl acetate (vitamin E acetate) have been reported as diluents. In most reported cases of EVALI, additional flavoring additives are also added to products.

Although many of these diluent agents and flavorings have been “generally recognized as safe” for oral ingestion by the FDA, recent research shows that when heated to form an aerosol and inhaled, conditions including bronchitis, bronchiolitis, acute hypoxic respiratory distress, lipoid-associated pneumonia, and pneumonitis may result. [1]

The terpenes used in vape carts to dilute and reintroduce flavor and aroma (which is lost in some extraction methods, like BHO) also produces harmful byproducts when vaped. [2]

Another problem with vape pens and e-cigs is the cheap atomizers/coils used. There have been confirmed cases of these coils/atomizers leeching heavy metals into the vapor produced.[3]

Dry herb vaping is the only medically endorsed inhalation method of marijuana consumption. Plus you get to keep your already vaped bud (AVB) to make edibles! If health is truly a concern for people, then dry herb vaping and edibles are really the only options. But that's not to detract from the risk mitigation approach. I will very occasionally smoke a joint or a bowl. No more bong rips for me ever again tho.
