79It is also apparent from the Court’s case-law that if there is uncertainty as to the existence or extent of risks to human health, a Member State must be able, under the precautionary principle, to take protective measures without having to wait until the reality of those risks becomes fully apparent. In particular, Member States must be able to take any measure capable of reducing, as far as possible, a health risk (see, to that effect, judgments of 1 March 2018, CMVRO, C‑297/16, EU:C:2018:141, paragraph 65 and the case-law cited, and of 19 November 2020, B S and C A (Marketing of cannabidiol (CBD)), C‑663/18, EU:C:2020:938, paragraph 90).
