Help Can cannabis oil be taken instead of an antiemetic?

[JazzyWolfWhistle]

so, I want to overdose on opioids, which can get, but I can't get prescription antiemetic drugs, which you need to take so you don't vomit out the pills you swallow to kill yourself.
I read online that cannabis oil can be taken as an antiemetic, has anyone else heard this?
If you can look at it and see what you think I'd appreciate it.
Thank you.

If it's all you have I guess, but I would not count on it
