well i already know what you mean by salvia gravity and i liked it....it really fucked up my typing cuz i was trying to support the weight of my arms with my fingers on the keybaord while typing so i was typing like this to my friends: likt hettte wlallllsss sare vlosimg innnnnnnn.....it was pretty intense and fun...didn't last long tho =/ wh ich i guess at that volume of being fucked up you wouldn't want it to last hours....i only took one hit, but it was a massive fuckin hit..i cashed the whole bowl in one hit and took it all in (it's a decent sized bowl too) then i was holding it and when i let it out it hit me..i think i dropped my bong and it did a flip and landed standing up on the floor too....lmao....my wife's gonna read this and crack up i can already see it....
