Title should be enough to to get the general idea of the situation but here it goes. I had been planning a trip with two local friends with the intent to cross country for a music festival. I was intending to drive while the other two intended to fly. I offered to take some of there camping gear as it would be cheaper then them flying with it. I request both of them disclose any and all drugs that they may have packed as I was requiring that I be aware of it to be willing to drive with it. They both stated they had very little to nothing above what I was expecting. After getting to the destination it was discovered that one of the two people had put an ounce of what is a federal crime everywhere in my car and didnt bother to tell me. Thankfully I was not pulled over or charged but this person is acting as if its no big deal and asked the other friend to even lie about the situation to me. I feel I am being gaslight because he is not taking any responsibility for his actions and it saying its fine because nothing happened. I feel I was taken advantage of and that he does not value me as a friend. AITA for wanting to tell him to fuck himself and remove him from my life entirely? I have not spoken with them fully regarding my frustrations and the fact that I know they tricked me. We are now approaching another event the group of us planned to attend and I am at the point I want to put my foot down and tell him to actually fuck himself and remove him from current event. AITA for now telling him this was the straw that broke the situation weeks to a month after it happened?
