Has anyone passed out after smoking?

Last night my bf and I smoked and after around 10-15 minutes my bf started saying he wasn't feeling well and started taking deep breaths so I told him we should go home since we were near my house. When we got up he said he really wasn't okay and a few seconds after he fell and passed out, since I panicked I don't know how long it lasted but my guess is around 20-30 seconds, he then woke up and said he was okay but it really scared me. Also something worth noting is that a few days ago something similar happened to me where I was also taking deep breaths and felt like I couldn't breathe but I didn't pass out. Both times happened from the same batch we bought a few days ago, could it have something to do with that?
