I am moving to Austria from u.s.and I want too get high 1 last time before I leave. But I fear that if I eat pot brownies they will somehow find out(through drug tests) when going through customs.I ma eat them 1 month prior to leaving so I can make sure they are out of my system before flying. I only smoked twice in my life so I'm kinda paranoid about pot and getting caught haha. My fiancee told me that when she came to the u.s. try checked her hair or something. I heard you can check if someone has gotten high by checking their hair. Thanks in advance for teh help.
