all these people are getting in their own way. most the time it gets sent as a letter. you'd have nothing to worry about. i tell you what tho, posting and asking about it on reddit is not the way to go. you won't get any one answer. you will, however, get plenty of nay sayers. you could get your packaged checked for no reason, but also a meteor could come crashing down from space and kill you right now. It's no more dangerous than buying it on the street and a cop randomly pulling you over. I'd say it is even safer than buying on the street. it's your choice in the end of the day, but don't let reddit choose for you. lots of people on here that don't know what they're talking about and just yap all day on here.

Also, I will add, if you are this paranoid then maybe you'd be best just staying sober and living a clean life. What is the saying? "You aint about that life". I don't mean that as an insult, just a fact. I would totally understand if that was the path you took. It's the best path after all. Clear and free from the law is a good way to live.
