Acute use of high-potency cannabis impairs memory and increases false memories, regardless of whether it contains CBD. In a study where 80 cannabis users either stayed sober or purchased and inhaled one of three high-potency products (flower with ≥20% THC without CBD, flower with ≥20% THC with CBD, or concentrates with ≥60% THC with CBD), all three cannabis products increased susceptibility to false memories. High-potency flower with CBD impaired free recall, while flower without CBD and concentrates impaired source memory. CBD did not offset cognitive impairments, and users self-titrated concentrates to produce comparable intoxication and impairment as flower.
