Don’t see how that would be any different to now - you would still be subject to chance of random search and would be prosecuted or fined etc if had made an incorrect declaration - that is no different to someone making incorrect declaration that nil to declare and using existing Green Lane - there is already the chance of random search, fine/prosecution/ seizure etc if incorrect declaration. Slightly off topic I’m staggered to see the number of elderly (of whom by statistics many of which are likely to be on at least some medication) using the Green Lane and not declaring medications.
