Hey all. I appreciate everyone's feedback on this. I feel it's only fair to fill in some of the blanks. I do have heart problems that I take medicine for (a lot is wrong with me physically), but it's stable at this point. Even though I'm a decade into my very regular smoking, I'm only in my mid-twenties, so I hope I'm not getting too old! I'm going to lean towards I being something to do with the herb itself because I've been smoking far too long to send myself into a panic attack. And plus, my husband was also smoking with me and experienced the same issues as me. Now, mind you all, we only smoked two hits. I was even high when I was experiencing these side effects and this is definitely not one hit wonderweed. I've been to Amsterdam and I explored many different varieties, both sativa and indica and hybrid, and I've never had anything like this happen before. What chemicals could we be reacting to in the grow process? I know nitrate was mentioned but I couldn't find much about how it would affect a person.
