lol yeah eating is definately the healthiest, with vaporizer's in close second. Now when you add the bud to the water you want to make sure its ground as fine as possible, that way theres more surface area and the THC and other cannabinoids(lol its trying to tell i spelled it wrong!) have a better chance of being leached into the butter. And a vaporizer essentially boils THC without burning any plant matter. Good luck and happy toking!
