Panicking over something someone else did?

When I was 8, I was drugged and SA’d. Ever since I’ve had a deep fear of being under the influence of anything. Anything that has drowsiness or loopiness as a side effect sends me into a full panic, sometimes even thinking about it does.

Tonight my fiancé went to go get high with his friend. He told me beforehand and everything. I’ve seen him smoke weed before, it usually just calms him. I’ll sometimes join if I know he’s around to keep watch on me. He calls me pretty late, panicking and crying. I try calming him down, talking him through it. Then he starts slurring his words really badly, I could hardly make out what he was saying. At certain points he’d start making drawn out noises, eventually just becoming completely unable to string words together.

For some reason, I started to have a panic attack. A really bad panic attack, too. I didn’t understand why. I know it’s just weed and he’s probably just greening out (he also didn’t smoke but took a “mystery edible” from his friend, so idk what’s going on). So why did I start internally freaking out? It’s not like I’m high or anything. I thought into it and I think it’s just because of the trauma I have with being drugged? If so, that would really suck because he likes to get high and wants to more often. I don’t want my issues to bleed into his wants. He doesn’t know that I’ve been panicking and on edge since, he eventually fell asleep over the phone. I don’t know if I should tell him or not tomorrow. I don’t want to ruin anything for him.

Is it possible to have weird triggers like this? Or is it unrelated? I feel like I’m losing it.
