Does smoking marijuana 8 hours before a colonoscopy effect the anaesthetic?

Smoking marijuana eight hours before a colonoscopy can potentially affect the anesthetic. THC, the active component in marijuana, may alter the way your body metabolizes anesthetics, potentially leading to unpredictable effects. Additionally, marijuana can impact respiratory function, which may complicate sedation. It's essential to inform your healthcare provider about any substance use prior to the procedure to ensure safe and effective anesthesia management.
