For me, the best method is through a bong, plain and simple. Smoke it quickly, try to finish the whole bong pack in one or two hits... expecially if its an extract. In my experience, don't smoke bud first, it lessens the salvia effects. Feel free to smoke it during the trip, but you won't need to. Also, try to be in a calm state of mind when you smoke it, being hyped up or nervous changes the trip.
