i tried salvia once. I first had a gravity bong bowl of dank weed. Then i had a bowl of 15x salvia in the gravity bong, which is the strongest hitting thing ive ever used in my life. It seemed as if it just supercharged my high. So ten minutes later i had another bowl of weed and i got way stoned. My friend had a bowl of salvia (after his weed) and he started tripping out. He tripped for 10 minutes, and i was his sitter, along with my sister. Well after that i smoked yet another bowl of the dank weed, and 5 mins after that bowl i started tripping. It looked like my kitchen was going to eat me, but i wasnt scared. It was way fun, even though my trip lasted like 20 seconds. However next time im going to either just use 25x with weed or 15x without weed.
