Is something off?

I’m an avid weed smoker (7months-mainly pens/occasional flower) and I have been trying a variety of brands to see which I can keep in rotation. I finally decided to try a Plugplay as I have heard of it but never actually bought my own. I got the melon dew flavor and I enjoy the taste very much, the pen also gives a nice cloud.

Anyways about a week later of routinely smoking the pen, I just started being very paranoid/anxious with my stomach killing me. I have little appetite and I am already slim and I lost 6 pounds. I have brain fog/headaches and no big news/changes/ or anything has shifted in my life during this time.

I’ve smoked about half a gram in 10 days which i don’t think is a crazy amount. Like I said no changes other than the brand I’ve been smoking.

Obviously my first thought was the weed, but it doesn’t necessarily mean it’s the brand and could just be me.

Just curious and doesn’t hurt to ask around, has anyone else had a similar experience? (I have cut down on smoking very much to see if my symptoms start to get better)

Edit: Major typo makes me look even more dumb. I started getting very paranoid/anxious AND my stomach was also killing.
