I’ve never been a big user, but as I’ve grown older, pot has made me pass out more than once. I took a drag off of a joint at a festival a few years ago and passed out and couldn’t be revived for 5-10 minutes. They said my blood pressure dropped dramatically. I’m wondering if this happens to anybody else

Couple of things it could be:

  1. You locked your knees without realizing it, shut down the blood return from your legs, then had a drop in blood pressure due to decreased blood return to your heart causing you to pass out.
  2. You took a big hit, expanded your chest, held it, decreased blood flow through your thoracic cavity due to the increased intrathoracic pressure then a blood pressure drop as above.
  3. Your vasovagaled yourself somehow (bearing down on a held hit maybe or just due to weed effects) which is increased parasympathetic nervous system tone that drops blood pressure
  4. Some weird shit 🤷🏼‍♂️, the body can be odd and changes as we age so maybe you just can't smoke weed now cause of the earlier mentioned weird shit

I agree with your doc (I'm a family med physician), don't smoke if all of a sudden you're passing out.

Thank you very much. It’s happened multiple times and every time I was standing up. Fortunately, I don’t find the effects of cannabis super enjoyable so I think I’ll just stop.
