I dont think there are restrictions but..that said..I would advise against it. I have discovered over the many years or travelling in and out of the BVI that C and I officials and the TSA do not always know all the rules and can apply their own instant judgement..that might ruin the start of a great vacation. Leave them at home and you might be able to get some on island..but that I dont know for sure.As a sidebar and more serious..but a US citizen just spent 6 weeks in jail on Tortola for carrying a gun on his private jet..even though he had a US permit for it.. A fine of $50,000 and time served finally got him released with his plans of buying a multi $$$$ home in the BVI's in ashes and his psyche severly damaged. Every country has its own rules....
