Grow up a bit, at least a couple more years...
LSD was my first psych... I took it when i was 16. That was a generally good time in my life... At 14-15, i wouldn't even want to imagine it... I was depressed, the type of kid who over thought everything. at that age i was hating my life... Its strange to think back on it that at that time in my life i was asking myself "why not just kill myself?" and other than a messy cleanup for whoever i couldn't think of much... pot helped that, it broke up the everyday monotony of life... I started to just let go, stopped worrying about things that were far beyond my control and just let things happen as they would.
I was at a stable and mature mindset by the time i was 16. i had a job, i was happy, and with a couple of exceptions life wasn't bad. I dropped and had an amazing trip. Still, maybe in a few years i will look back on it and decide i dropped to early in my life. Perspectives change with time, you might think you are mature but you still have alot of growing up to do and alot of things to experience. But at least you are mature enough to ask if its a good idea.
my advice is to go onto erowid, read everything you can about everything you want to try, especially the experiences. Good and bad, to fully judge the potential of what might happen. But no matter how much you read about it, you have no idea what it is like. for me LSD was like nothing i could ever imagine, and more than i could have dreamed for...
Salvia is a ridiculously powerful substance. A good breakthrough trip would teach you a 5 minute lesson in respecting the power of psychedelics... Salvia could be doable in that, it doesn't cause too many life changing perceptions but it is very powerful. 1.5 hits of lsd caused me to see the world differently, a small bowl of salvia ripped reality to shreds and hurled me into new universes... but i didn't get anything out of it other than a "what the fuck just happened?" sort of feeling... if you do it, do it around another person where there is not anything you could hurt yourself around...
my last salvia trip was at night while camping, i was thrown into some fucked up tv set, and then in what seemed like final judgment which caused me to think that i had died. i started walking up a staircase to the next plane of existence... i got to about the 2nd step when something tackled me...
i hadn't really made it vocal that i was taking a bong rip of salvia so no one stopped me from getting up... so i walked around the fire pit. and turns out that the "2nd step" was over the fire pit where there was a considerable fire going... i slammed my foot down into the coals. the salvia kept me from feeling any pain from this. and a girl tackled me out of the fire and into a tent which broke.
i came down at this point to a bunch of worried faces of my friends. i didn't know that i had stepped into the fire until they told me... looked at my foot to see a few minor 2nd degree burns, things could have been worse.
The point is that for that short duration of time, you will have no idea what you are saying or doing, anything that might ordinarily be very painful you might not feel at all...
. I'm impressed, tho I ought to have expected it
