I have bought some Kratom from the Netherlands. I am very nervous about taking it - I have no idea whether it is legal in the UK or not as I have seen conflicting info. my order arrived today in a clear plastic envelope marked only "RVB" . The Invoice states "this product is not meant for human consumption" I cannot take this as I have no idea what it is or whether it is indeed Kratom. I used de kratomshop.nl Any advice would be much appreciated.
