What Side Effects Are Caused On Smoking Marijuana During Colonoscopy?

hi, i just had a colonoscopy this afternoon, i may or may not be going to my friends house later where they will be smoking marijuana and such and i do not know if i should go. i am worried about possible drug interactions with the propofol that i was given for the anesthesia. I need an answer on what may happen if i go and whether or not i should, thankyou
