While legal access may reduce some harms associated with illicit supply chains, inconsistent state and federal regulations create a fragmented landscape where patients may receive products with markedly different cannabinoid profiles despite identical labeling, complicating efforts to establish reproducible therapeutic protocols or adverse effect monitoring. Healthcare providers counseling patients on cannabis use should remain cognizant that regulatory changes often outpace clinical evidence and that patient safety depends on direct conversations about product sourcing, actual potency verification when possible, and realistic expectations about therapeutic claims. Given these regulatory uncertainties, clinicians are well-positioned to serve as trusted sources of harm reduction guidance and can support patients by documenting cannabis use patterns and effects systematically, thereby gradually building the evidence
