I too got alittle paranoid about this and always throw away my old bottles and make sure now to only get a delivery once a month after funny looks from the FedEx lady. If you don't draw attention to yourself and be obvious, you shouldn't have a problem....i.e. don't answer the door naked and drunk.....ha ha....don't open the door, rip open the package and take a handful right in front of the delivery driver.....common sense things like that. I also don't tell friends about it anymore or talk on the phone (cordless) about it to friend's anymore, never know when officer friendly is down the road with his laptop trying to intercept your call.
