Anything you wish you could've known before you started and would like to pass on? Opsec, getting new customers, possible blunders, etc? Dealing with LSD, Marijuana+concentrates. Don't deal with much lower end stuff but tips for those guys would be good too
Use Signal with all your clients, they will likely be terrible at consistently using whatever stupid codewords or not just directly saying "you still selling LSD? how much for a 5 strip?"
