Sales of products containing ephedra extract not containing ephedrine remain legal. Health Canada has investigated the risks and benefits of pseudoephedrine and ephedrine/ephedra. Ephedrine is obtained from the plant "Ephedra sinica" and other members of the genus "Ephedra". The sale of ephedra alkaloid-containing dietary supplements remains illegal in the United States. Ephedra is a medicinal preparation from the plant "Ephedra sinica". However, several reports have documented a number of adverse events attributable to unregulated ephedra supplements. The same may be true of other herbal products containing extracts from other "Ephedra" species. Following Bechler's death, the FDA re-opened its efforts to regulate ephedra use. Ancient Soma most likely consisted of Poppy, Phaedra/Ephedra (plant) and Cannabis. This suggests that its close counterpart soma is also made from the Ephedra plants. It is a combination of theophylline, ephedra, and hydroxyzine. This points to ephedra as being a strong candidate for soma. Products containing ephedra extract remain legal to this day. Sarianidi says he also found dishes with traces of cannabis, poppy and ephedra.
