No, I have not. But have you honestly tried ayahuasca? I bet if you did you would agree, not even close. I have done 40x and I just laughed my ass off for a couple mins. Try any of the DMTs and you will find god... or the devil. Both will change your life for the better

If all you did on Salvia was laugh, then you just got the buzz of it, not the full trip. It takes like 5 times of trying it until you actually trip, but when you do, whew!
As soon as I got back from my first trip(first time tripping on anything), first thing I said was I'm never doing that again. The fear was so intense, but it was a good fear, and the deja vu was unbelievable.
But yes, Salvia will send you to the spirit world. And it only lasts 5 minutes, of course there, there is no time.

of course I ended up doing it again, and a few more times after that :D. Now it's illegal where I'm from and I haven't been able to do it for more than 4 years.
