One of two things.. hes gonna get it back and be a good businessman and send it to the correct adress, or He's gonna be a dick and keep your money.
He will probably read your email before he sends out the product considering he usually doesn't send out the product till a month after he gets paid for it. If he does send the product to the wrong address it will probably get returned to sender and the sender address will probably be a random apartment complexs street address with out a number specified, to take care of just such a mishap. It will eventually end up getting thrown away most likely. If it gets delivered to a house the person might open it I guess, but it wont link back to you if you used a fake name for delivery, and it wont link to the vendor either because he probably wore gloves and used a fake return address etc. Nothing is likely to come of it unless you used your real name. If you used a real name with the wrong address there is a small but significant chance that they will open your mail and freak out that they got an envelope with white powder in it and call the police or something. The cops will likely raid you if that happens just to find out what the fuck you got white powder sent to a house for and maybe ask you what it is since they wont be able to identify it very quickly. If you did get it delivered to your name I would run DBAN on your computer and wait it out for a while, keep your fingers crossed that the vendor checks his email before sending it out. Also would have helped if you used Tor, your ISP could check your internet logs and see you connected to that vendors website if they do an investigation on you, and chances are you didn't encrypt E-mail either. But you don't have much to worry about. It is worth noting that 4-aco-dmt degrades into 4-ho-dmt even outside of the body, so you are outside the scope of grey area and are certainly considered to be trafficking in a specifically scheduled schedule one substance, even if only .01 percent of the 4-aco-dmt has degraded to 4-ho-dmt, which is probably has. But really I would not worry about it!
nah this guy has a nice heart and all so he'll send it to the right address instead of keeping the money the wrong address it was sent to (IF he sent it) does not exist i think im safe i'm also drunk (and I NEVER drink, im way against it) cuz i was so fucking stressed man so i could be being stupid too. lol
He would be extremely stupid if he used his real return address to send drugs from, especially something as dark gray / black as 4-aco-dmt. That is as close to scheduled as you can get with out it being straight up scheduled, I think it is likely it would be charged as a schedule one if intercepted, far more likely than 2c-i or something. But I really wouldn't worry much about it.
He is unlikely to resend it if he sent it to the wrong address. For one he almost certainly did not use his real return address, and for two even if he could get mail from the box he put as the return address, he would be stupid to. For all he knows you are a cop and are doing surveillance on the return box, and only made up a story so you could catch him getting the returned mail. It is risky enough for vendors to pick up orders from suppliers or distributors, much less picking up return mail from consumers or dealers. Senders are far safer than receivers, and product is sent linearly from those most likely to be investigated down, I doubt he will compromise his security for a mistake that was not on his part and can't really blame him.
Haha both now that I think about it. But I was referring to the vendor, who I actually believe would send it out with his address as a return address.
