i first smoked regular salvia leaves and obtained only very mild effects after smoking about 3 full bowls. Then i went and bought standardized 25x extract which costed about $10 for just a little pinch. When i got it in the mail i was disapointed because of how little i got for 10 bucks and i was thinking "if i smoked 3 full bowls and barely felt anything what the hell is this going to do?". But i had no idea just how strong this little pinch of leaves were. I smoked it and held it in my lungs and quickly lay down on a lawn chair in my yard. What happened next was incredibly wierd and hard to put into words. First of all i couldnt move at all, i felt like something was pinning me down to the lawn chair and just moving my arm took incredible force. I felt as if there were thousands of layers pinning me down and every inch i moved broke though one of these "layers". There was also this strange voice telling me which layer i was going through, although i couldnt really understand what it was saying, but it was in this strange rhyming voice. Maybe this sounds kind of cool but it definelty wasnt enjoyable. After about 10 minutes i could start moving again after i forced myself to get up through incredible effort but i was still shaken over the overwhelming experience.
