While more potent than smoked cannabis, vaped liquid formulations with Δ9-THC may have a similar PK/PD profile through modulation of Δ9-THC delivery by consumer use behaviors. Potential health effects of high-potency vaping products with Δ9-THC in liquid form need to be carefully studied. Lastly, researchers should continue to think creatively about how this important work can progress while restrictions on Δ9-THC continue to hinder research.
