I tried acclimating myself to salvia before going to level 5 with it by taking rips of it throughout the day. After 2 or 3 days of taking a bong rip of salvia every 3 hours had got me kind of used to the state of being you are in on salvia. And, yes, your tolerancy definitely goes up. At first it took just a wisp of smoke for me to get those initial bugged out feelings now it takes 2 or 3 which is why I use the quid method.
