How long can I eat an edible after coke

[Hairbrushes]

Was wondering say if you did 3 tiny lines of coke and did last one around 6:30pm, when is it safe to have some weed in your system. It's now 9:30pm

Threads I read is only about doing the two together at same time and really affects your heart and cause panic attacks.

I'm never doing cocain again
I want to chill and sleep.

Now? Weed doesn't have any interactions...
