It had an effect on me, I just didn't like it. wish acid wasn't so hard to find, For me salvia was a dark trip, both times, one Time I took a huge hit of 10x with the intention of walking outside and seeing what the world looked like while triping on salvia....yea...didn't happen, never made it out the house, got stuck in a mirror world trying to open a door, and they're wew infinate amount of doors, and I was afraid if I let go of the doorknob then I wouldn't know which door got me back to the real world and I could be stuck there forever, I tried franticly to open the door. did this while wife was asleep, we had the door tied on the other side to keep the kid from getting out while we were asleep and getting into stuff, couldn't think well enough to remember that, to me the door just wouldn't open. Luckily my wife heard the door shaking and opened it, and seeing her was like` seeing a link to the real world, and I held on to her while it faded away, saying something along the lines of...yea....uh...not my thing apparently...
The other time I tried it I was playing american mcgee's alice, I took a hit, and the whole world started shaking violantly, like the physical plane was jolting and my astral body was loosing sync, we had a kitchen bar that I could see from the living room where I sat, no one else was home, yet someone was talking to me from the kitchen, and I was talking back, it was like I new this entity for a long time, we weren't friendly, he was kinda prickish, but not scary, though the jolting was, Oh, and my daughters white rabbit was running around looking for something for my daughter, apparently she was a queen over a kindom in wonderland...really wierd, but yea... I ended up writing a short story based on that trip....but yea, never had a bad trip on acid, no matter how much I took, was always able to steer the experience where I wanted it, couldn't do the same on salvia...I'm sure some can, but I can't and its probably that lack of control that kicks in the fear I feel when I'm on it.,.
