If you wanna smoke some plant material directly and get a tryptamine high, you can smoke cebil or yopo seeds.
Of course, these guys give a 5-meo-dmt high predominantly. (yopo has some nn-dmt in it, but still)
5 meo & bufo are significantly stronger by weight, and the concentrations in those seeds are high enough that you can smoke a bowl and get high.
SWIM finds the body load and the darker, colorless character of those substances annoying. Very rarely if already high on something light and colorful, SWIM will break out some seeds and puff them for the booster factor, though.
