i'm pretty sure DPH (benadryl) can be lethal by itself. i've experimented with the deliriant drug class, and i've gone up to 750mg dph. i've read trip reports of people going to 1-2 grams, 1.5+ is called "Eiriel". at that point the risk of death is high, but the dose for different trips is different. at some point over 2 grams i'm sure it's extremely lethal- but not at all comfortable.
before you'd die, i'm almost 100% sure you'd trip first. it's a horrifying drug class, and i seriously suggest researching DPH if this method interests you!! people say it's a psychedelic, but it is
NOT. anyways, be safe, and we're all here if ctb ends up being a choice you don't want to make.
