First weed ever. What did we do wrong?

We had our first weed session ever. Never had any of us smoked or eaten any weed before. We were using a Davinci IQ2.

I loaded the IQ2, powered it to Smart Path 3 (I read somewhere this is where I should start) and she had maybe 4 puffs from it and I had 2 during the 8 minutes session.

When the session ended, I powered it to Smart Path 4. She had 1 puff and it started to get her high, and she became nauseous and disoriented.

I was feeling happy and contemplative at the beach, and had my first puff on SP4. She might've had another puff and warned me to stop because she wasn't feeling well.

Then it hit me. My heartbeat went skyhigh, and hers too.

So I became anxious and worried we might have a heart attack. We're athletic and exercise 3-6 times a week.

She grew sicker, feeling cold, anxious, dizzy, like trash, she said she felt her stomach was bloated and going to explode.

I was alright, just a bit off, like I was thinking it out of my head and had to move the thoughts there. But I also was very, very worried for her. I gave her plenty of water , but she didn't want to eat because she wanted to vomit. She didn't vomit though.

About 4 hours later she was feeling better, just very tired.

What did we do wrong?
