Don't bother with buying plain leaf unless you plan on doing a home extraction with it. VERY few people experience any sort of high from smoking the plain leaf, let alone a psychadellic one.

I would highly recommend getting standardized extracts as well, as I've found they burn better and provide a cleaner feeling high, with no after headache. The same can't be said about non-standardized, which after smoking myself and all my friends get a throbbing headache.

I would also recommend getting 5x and then either 15x or 20x because while you'll notice a difference between 5x and 10x, it won't be terribly drastic. Salvia isn't the most comfortable of highs, but it's definately psychadellic and something worth investigating for anyone who is into that sort of thing.

I'm a salvia hard-head, but 1 gram of 20x can put me on a good 7-10 'spiritual journeys'. ((Ha! Kidding, I just do it to get fucked up. lolol))

Pack about 1/10th of the gram of extract for your first time, and hold a butane torch lighter over it while inhaling through a bong with ice and water for best effects. Take as much as you can, hold it in for a goof 10 seconds, exhale and immediately take another hit. 1-3 hits will tear your mind into a bajillion pieces. Lay back and close your eyes, expect to be flying through fractals in no time.

For some people more then 1 hit of 20x is terrifying and disorienting. I find it to be fucking amazing. Find your own personal preference and repeat.
