try looking @ products intended for nasal decongestion.
However, I did a quick internet search and for Canada-Currently, the maximum allowable dosages for Ephedra/ephedrine in products is 8 mg ephedrine/single dose or 32mg ephedrine/day. Products containing Ephedra which are marketed for traditional medicine, will continue to be available, provided they do not contain caffeine and that the ephedrine content does not exceed 8 mg/dose to a maximum of 32 mg/day.
