Also, hypertension risks are generally a problem for MAOI prescriptions: people who take MAOIs every day. With DMT, a MAOI is only consumed once, with the DMT. DMT is rarely taken on a regular and frequent basis, so it's unlikely someone would be consuming a very risky quantity of MAOIs over the long term.
MAOIs may increase DMT risk in other ways, but I don't believe hypertensive crisis is an issue for that specific combination.
