Cocoa v. Coca.

This is actually something I’ve wondered for a while. Are the proper botanical names Cocoa and Coca related in any way? They certainly look similiar. One tastes great on a cold and blustery day. And one might get you 10 to 20 in the slammer. So are they related?

Thank you in advance to all who reply:)

Coca comes from the Quecha word “cuca”

Cocoa comes from the Nahuatl word “cacua”.

The two languages aren’t related.
