Your landing page screams for A/B testing, but not just of different permutations of this page but of entirely different product names going for different market segments.

If you wanted to market to this particular segment, you could more explicitly make mention of how well kava goes with cannabis.

EDIT:

I have a KAVA tea mix that some people told me was really good so I threw together a website - and will sell it shortly. But I really have no idea how the hell to promote it. Thought I would ask. :)

If the tea is mostly caffeine: maybe sponsor some hacker event?
