Drug info - SWIM is going to do salvia

[jm1g]

Hi guys... SWIM and his 6-7 friends want to do salvia. They all chipped in some cash and bought some "salvia" from a smoking shop, which turned out to be kratom. they smoked it and it didnt do anything, leaving everyone a bit annoyed. Anyway, they are going to buy some more salvia, and SWIM has been tasked with buying it.

Salvia usually comes in 1gram vials that SWIM has seen. SWIM has been reading threads on this forum and come to the conclusion that they will need a higher dose than 5x, even tho all but one of the said group are salvia virgins. The reason SWIM has come to this conclusion is because for 1g to work for everyone, not much is to be used.
The one person in the group who has done salvia, says that 2 bongs are needed to feel the full effects, so SWIM is going on this basis. So, 2 bong for 7 people. What strength shold SWIM buy to go around for everyone?

Another question. the first user in this group will have 6 spotters, who will all be sober. How long does it take the first user to return to a sober state? Because if everyone in the group is going to be taking it, does this mean that by the end, there will be no sober spotters?

SWIM looks forward to reading your answers, and if anyone has any advice for this person and his friends, they will appreciate it.
