Nope. Dilantin (phenytoin) and morphine (opiate) are completely different classes of drugs and should not cross react on a drug test.
Yes. It will show up as THC.

Will it wrk for a mouth swab
Yes
I take ultram for back pain 2 evey 6 hrs. will that show up positive for opiates on a oral swab drug test?
It shouldn't do. Zantac is in no way chemically similar to meth.
The average mouth swab detects use for up to 48 hours.
It's likely that you will pass a mouth swab test if you smoked weed 4 days ago as the detection window for THC in saliva typically ranges from a few hours to 3 days, with occasional cases lasting up to a week. However, this can vary depending on factors such as frequency of use, metabolism, and individual differences. Staying hydrated and practicing good oral hygiene might help clear traces of THC faster.
Probably because it ends up in the blood stream through the sinuses.. I seriously suggest if you are doing heroin that you stop... Very dangerous drug!
