listen, it is perfectly legal to buy the fina pellets. it is illegal to introduce them into the human body. if they track it so what. they still have to perform a sting and catch you injecting it. its not worth the money to the feds to get 1 person on use. they look for people ordering this stuff in mass quantities, no pun intended. then they can get that person for intent to distribute which to them is huge. but for ordinary joes like us, no they arent going to come busting down your door, raid you house, strip you down and check for needle marks, take you to court to find out they messed up during the process and have th case thrown out just so they can try and bust one guy for personal use. now if you were driving and got pulled over and they searched your car and found it then they can ask questions but again, they would have to prove you are using. hope this helps.
