The thing i'd be most concerned about is the taste/smell both during the salvia vaping and then afterwards with your Da Buddha (which should get hot enough, btw, around 3 or 4 like you mentioned). Perhaps you could ready some replacement tubing (if you're still on the tube) and find Iso or something similar to clean your wand and screens...such a bad taste, salvia. Maybe it's just me, but I found my first experience with salvia to be particularly enjoyable. Some friends and I had just ordered Swiss Chalet and were waiting for the delivery guy when someone showed up with "the blackness". We smoked and then... I remember throwing punches around and preaching from my chair. Then laughing, dancing, and jumping heel clicks! Actually, there was more falling down laughing than anything else, and certainly no preaching. The farther one travels, the less one knows. Arrive without traveling. Do all without doing.
