Probably alone, maybe with a family member.
My mother has been quite unwell over the last couple of years and a naturopath she occasionally sees has been trying to convince her to try "the medicine" (as they call it) for a long while now but I think she finds the thought of attending a ceremony a bit overwhelming.
So I might consider doing with her at home if/when she's well enough again. DMT is easy enough to get i'd just have to look into the MAOI. I'm sure DMT nexus will have me covered there.
