I understand why you mention it (both make you feel good), but are you sure you want to draw lines between your service and a much-abused substance known to be highly addictive?
The truth is, it's a much more dangerous risk for us to die without anyone knowing we exist.
Instead, you're the first Happiness-As-A-Service (HAAS) company in the world!
It would draw direct issues - there are seedy massage providers out there offering sexual services under the guise of "massage".
So it's very dangerous to use the words "massage" and "happy" together. You'll start ranking on google for some very questionable queries.
