Hello, I made a new account for this question. I'm in Thailand at the moment and tomorrow I can fly back to my home country. The only problem is that I am terrified. Me and my roommate gave a party at our apartment and it went a bit crazy. There where many drugs... I don't use them myself but they touched my stuff like laptop and tables. I'm afraid if I fly tomorrow and have these things with me the drugs dogs will sniff me out. I will have no drugs on me, of course, but I really don't want to be a suspect of a smuggler. My question is what is the best way to clean my stuff so not even the best drug dogs could sniff me out. I think the removal of a chemical ,so not a trace is left, falls under science. thans in advance for the answers (sorry for my english, not a native speaker)
