Ya whenever I do salvia I found the best method is to take a bit, smoke it, feel a little something, wait 5 mins, and then smoke the dose you really want to do. Helps with the tolerance. And ya man, salvia doesn't work... ya know until you smoke some extract, and turn into an item in a dollar store, and attempt to beg this fat lady not to buy you. Or when you end up as a pot on a shelf, and try to get your friend to stop laughing, because you KNOW there is a giant on the way, that has a hankering to make a meal, with you his favorite pot.
