ok heres my experence with salvia:
i had bin high on pot for about 1 and a half hours and i was blazed then i took a big ass hit of the salvia and held for about 40 sec's and i didint feel nothing then i tried another hit and held for the same time and the next thing i new i was siting on my side with my legs curled up and pulled to my chest and i was kinda shakeing and i thought i was in a cave with water dripping on my face but it turns out it was just my own sweat.
salvia really isint a good mix with weed if u ask me o plus what i had was 10x i didint like it much and probly wont do it again
