This is a horrible idea. If you don't end up getting yourself noticed by law enforcement, you're still very likely to find someone who will take advantage of you to make a quick dollar.
I have friends who met up with people they'd been talking to on bluelight, and get ripped off several hundred dollars, and one was even robbed at gunpoint.
And in that situation, what the hell can you do? You're not exactly going to call the police and say "Uh, yeah.. So I was trying to buy drugs from someone I met off the internet, and dude totally took my money!"
So please, don't do this. If you're having so much trouble finding drugs, I'm sorry, but maybe you shouldn't be using them.
There are plenty of things you can order off the internet, legally.. Pods, Kratom, etc.. Other than that, I highly suggest you wait until you find someone you can trust. Trust me, when you're interested in drugs, you always seem to end up finding people with similar interests eventually.
But ugh.. Please don't look for illegal drugs from people on the internet..
And yeah actually tried to find people to sell you drugs on 4chan? Are you serious? Do you know what a troll is? 4channers will have you curled up in a ball and crying..
Although, I'm wondering if the OP is a troll himself?
