Will Medicinal Marijuana Alter How The Body Metabolize Dextromorphan Or

Will medicinal Marijuana alter how the body metabolize dextromorphan or doxylamine succinate? I'm curious as I am quite nauseaus from too much caffeine. I have had plenty of fluids within the last few hours but will have difficulty falling asleep without some for of sleep aid, can medicinal Marijuana and nyquil be used at the same time?
