No, its from legit sources. It's been a more and more popular diagnosis the last 5 or 6 years. I first saw it around 2018 in a legal state. One someone has it they kind of just have it and any THC use will cause the symptoms. It's n/v and abd pain characterized by recent cannabis use in a chronic cannabis use patient. I've never seen it in anyone who described themselves as moderate. Relief with hot showers and worsening with cannabis use are the diagnostic criteria other than personal/social hx.

The doctors I worked with felt like it was due to the low price and availability of concentrates.
