Salvia is not to be toyed with, But, ill post the first experience i had... I was like you, figured, id hit it hard the first time.
i obtained salvia, 21x oaxaca brand i believe (to this day, this is the strongest salvia i have smoked and i have smoked up to 40x extracts)...
i packed a decent hit, nothing happend, so im like.. "Wtf?"... Would estimate the hit at about 0.1 atleast...
Later on that night, i darkend my living room, smoked abit of green and loaded my "salvia bong" up with a small bit of green to plug the hole as to not lose any sally... i pack as much sally into it as i possibly could, (its a big bowl so it was well over your 0.2 mark, but still).. I put on a song "Karnivool - The Caudual Lure" and paused so that the second i put the bong down i could start the song...
I hit the bong, could sense something going on before i even finished the hit (I smoked the entire thing in one hit, i have monster lungs), As i put the bong down, i hit play, i feel reality start to shift, like in the butterfly effect when he is at the start of being transported to his lost memories, i think to myself "Wow, this is weird"... The first words of the song after the instrumental intro are "Ask the question" (i picked the song mainly for this reason as i only to psych's when i need personal questions answered)...
At that moment, the second he said those words, i noticed that i had tunnel vision, very bad tunnel vision, to the point where everything in the tunnel vision was BLACK, actually black, pitch black.. I started to get a lil freaked out, but calmed myself, but, the blackness continued to take over my entire eye sight... (This all happend in about 30seconds, bong hit, weird felling, play, intro, freaking out) So, im 30seconds in and already starting to freak out a alil, but, i compose myself and reassure myself this is what i wanted...
another 5seconds goes by and i completely forgot i had just smoked salvia... My vision is now black.. i feel something creeping up my left side up to my mouth, It then comes across the slit of my mouth, moving across the right side... Boom, Im disconnected from my body in an eternity of blackness (remember, my eyes are open), i see a line in front of me (i assumed this was where my head has been seperated from my body), and i seem to be floating above it...
At this point im totally freaking out, the song no longer exists, my body doesnt exist... What exists is my mind floating through a pitch black abyss... I would estimate this to be no more then 1minute into the trip..
Then, suddenly, i feel the same way i did when i first put the bong down, that "butterfly effect feeling" and i start see something... Its very familiair.. Its my neighbourhood from when i was growing up... im me, in a past memory in my front yard, watching an old friend ride his bike and do lil jumps n stuff from the neighbour across my streets driveway..
This calmed me GREATLY!!! I was really calm and happy and blissful.. so much happiness... But, as quickly as that first "butterfly effect feeling" came and went, it happend again... I get the feeling again and im transported back to this blackness... Its ok tho, im happy to be back in the blackness and await for what will come next.. I rememeber i had smoked salvia at that moment i thought, "Wow, this is what everyone was so scared of?" ... i then saw in the distance of the blackness, a giant gargoyle carrying something.. It gets closer and i hear "Salvia.... Salvia..." in the most deep and demonic voice i have ever heard, it was the gargoyle... As it moved closer, i could start to see what it was carrying..
It was carrying the very room i was sitting it, the entire room, i could see it as clear as day.. It was calling salvia to claim me as a victim for my previous thought of "this is what everyone is so scared of?" ... I got a lil scared by calmed myself and just s tarted at myself being carried by this gargoyle creature... Ms.Shiva never came to claim me...
once again, the butterfly effect feeling comes..
as it comes on, i suddenly start to hear music, its the song!! im almost home!!
the next place i visit is the band performing a live set for me in total darkness, with a faint purple background, pulsing to the sound of the music.. The band starts spinning upside down and around in all crazy ways, i started to feel as if i was on a rollercoaster..
The song is ending now, but, im still blind to everything, the darkness persists.. As the second song starts (THANK GOD IT WAS A HEAVY INSTRUMENTAL SONG!!) i start floating through this darkness, but, for some reason, there is alot of light/dark/pulsing purple around that if i focus on becomes more brighter and intense...
Then, the centre of my vision starts to come back, im thankful for this... The first image i see is the Earth (i used my ps3 for music and had the visualiser playing the earth).
So happy to be back home, had an amazing after glow.... Reborn.. Did not touch a ciggy for about 2 weeks, thats how intense this rebirthing feeling was.. I was literally a new me for about 2 weeks, did not drink coffee, smoke weed or ciggies, was alot more active in life.. But, alas, it diminished after a while, but, i will never forget the feeling.. I rarely smoke cigs anymore, i smoke pot once a week as opposed to blazing atleast once every hour and enjoy coffee in moderation...
Was a life changing experience for some very strange reason, i do not recall why this had such a profound effect on my life, but, it did and im thankful for it..
In conclusion, Do as you wish, its your life and your body... I did as you want to and had a very intense experience, was very scary but very calming..nothing i had ever experienced before prepared me for this.. I would rate it as a bad trip, there are alot of details i have excluded for personal reasons...
Posting this mainly as a guide to serve you that if you do plan on going through with this, make sure you have a trip sitter (i did not, i have no idea what happend to my body during this entire trip apart from when i was watching myself in the gargoyles box), Make sure your very calm and not scared of the experience your apart to par-take in, respect it but do not fear it and if you plan on taking such a large dose, dont be surprised if you forget that you just smoked salvia..
It will scare the shit out of u
Be respectful, Tread water, then swim.. Dont go scuba diving straight away like i did..
