A shaman who isn't me recently administered 6g of powdered Syrian Rue in diet 7up, followed 15 minutes later by 70 mg of yellowish mimosa spice (also in diet 7up). The shaman's subject reported experiencing significantly weaker effects than when he smoked 50-60 mg of the same spice. Also, the subject only felt effects for about one and a half hours. Why were the effects so short? Does oral administration cause weaker effects? Should the shaman wait longer to administer his spice? Should the shaman increase his dosage of spice? Discuss.
