Am I wrong for being pissed at my fiancé for smoking weed?

My fiancé and I have recently been planning to move out of state. Something that we’ve talked about for two years for better paying jobs for the both of us. We finally set the day we are moving for September 1st. Meaning we both have to drug test sometime within the next two to three weeks. I personally don’t do any type of drugs but my fiancé on the other hand smokes a good bit of weed so “quit” last week during my week off work. I started working again this week and came home this morning (I work over nights one week on and one off) and found cigar wrappers and the house smelled of weed. So I confronted him about since we’ve already told both of our families that we had plans to move the first of September and that with him smoking weed again he won’t be able to pass the drug test and I’m going to be honest I was pissed about it. He then told me that I had no reason to be mad since I told him at the beginning of our relationship that I didn’t care if he smoke weed as long as we were able to manage our bill. So am I wrong for being pissed about him smoking
