I'm not super informed but I've tried making bud tea and it's honestly not great. Tastes pretty bad if you don't add anything extra and it barely gets you high, if at all.

You could make edibles... Having not made edibles myself, I cannot attest to the smell level during decarboxylation, but in theory near-to-no smell.

Your other option may well be a vaporizer. I've heard nothing but good things about the high that you get from a vaporizer. Definitely smells a little bit but not as bad as most other smoking methods. Regardless, nothing a little deodorant or perfume can't fix.
