SINGAPORE – More than 444 vaporisers and related items were seized at Singapore's air, land and sea checkpoints between July 20 and 23. About 77 per cent of cases involved short-term visitors, with the remaining 23 per cent Singapore residents – citizens, permanent residents and long-term pass holders, said ICA. For foreign arrivals, short-term visitors who reoffend will be banned from re-entering Singapore, said ICA. Similarly, long-term residents who reoffend may have their passes revoked on a third offence. They may be deported and banned from re-entering Singapore.
