That is always a possibility, but there are ways to minimize that possibility. For example, I order everything domestic, and I order relatively small quantities. Keep in mind that customs is not involved when ordering domestic, and if you order a smaller quantity, even if caught, you likely won't be charged with intent to distribute. I also like sources that have extremely secure payment methods. There is no apparent transfer of funds, and no trail left behind like when you use western union, and the money transfer is 100% anonymous. You may want to look around at different sources and find the one who has the most secure/anonymous method of payment. The less trails that lead back to you, the better.
