Penalty is up to life in prison Its on same category as heroin But i think their swab tests and machine wont detect it. I also doubt dogs are trained to sniff kratom. That being said if you not do something really stupid like bring 1kg without label or worse put in package which say kratom you should be ok. Most hilarious story i heard is that one guy brought 3kg kratom to uk they actually search bag found kratom Thank god he had enough brain to put moringa label on package he found label on i
