Moderate "conscious" sedation with propofol anesthesia

[Roman]

I posted this in a few places today and wanted to start a new topic anyway...

 

I am scheduling a colonoscopy and they use propofol to sedate patients, but not entirety unconscious.  I've studied that this drug can cause hallucinations so I'm very concerned because I'm so sensitive I can't even be around second hand cannabis smoke without feeling horrible, it even can raise my blood pressure. I'm also not sure if I even have a typical HPPD condition because of my unusual symptoms and lack of professional care. But I'm now wondering if propofol is not only safe but could actually help me improve?
