1 gram of x10 will be enough, depending on how many people you're going to smoke it with. You can take quite a few hits from a gram so if it's just you by yourself or with a mate then 1g of x10 will last you for a few hours. It depends of how hard you wanna hit this stuff. I like to have a few drinks, listen to some music and we'll get through it in 2 or 3 hours without going mad. Salvia comes on quickly and is pretty fucking intense for what seems like 5 or 10 minutes but might actually be only a minute or two so really you wanna space it out over an evening, maybe smoke some weed and have a few drinks in between.

If you plan on smoking with a crowd of mates then get more, but too many cooks spoil the broth when it comes to Salvia because its a pretty personal drug that needs a quiet, relaxed and darkened atmosphere for you to really enjoy it. At least, thats what I think. I wouldnt compare it to shrooms in any way because you eat shrooms with loads of mates and trip together but you'll go far deeper with Salvia although only for a very short time period and it'll be far more personal than a mushroom trip and completely different in so many ways. You might come down feeling elightened, confused, talkative, stoned, paranoid or all of these things but the affects will usually be totally gone in 1/2 an hour. Then you can have some drinks, smoke a spliff and talk about the trip with a friend and maybe go back to the Salvia a bit later on in the evening.

Sorry man, started rambling cos it's 4am, my weed is finished, my beer is long gone and i'm bored. But yeah, 1g is enough for a trippy evening.
