That's a strange thing to say, why do you think that? I know a lot of people who don't have anxiety disorders who had an anxiety attack when they first got high, and yes they might think they need to go to the hospital. The physical experience of weed can feel like you're dying

Most people know you can’t die from cannabis no matter what so in my experience they just sleep through it. I’m assuming people with anxiety disorders can’t rationally think through this scenario when they have taken too much and end up going to the ER.
