Detailed answer

CBD is not psychoactive and does not impair driving. The catch: Swiss legal CBD flowers may contain up to 1 % THC, absorbed during smoking. Switzerland's zero-tolerance limit (1.5 μg/L blood THC) applies regardless of THC origin. Recommendation: wait at least 6–8 h after smoking CBD flowers; prefer THC-free CBD isolates or oils.
