As far as I know, that lifting of the ban was only in Utah. Actually, this was discussed a while back pretty thoroughly:
As far as making HOT-ROX with ephedra in it, it defeats the purpose of us ever having made HOT-ROX. We began developing HOT-ROX long before ephedra was ever banned. Tim had a conference with Bill and myself and wanted to develop a product that would make ephedra obsolete in terms of efficacy and safety. The original article explains a great deal of this. With HOT-ROX, you don't have to worry about beta 2-adrenergic down-regulation, nor excessive cardiac stimulation nor increase blood pressure due to lack of selectivity when it comes to ephedrine's adrenergic effects. You're also improving endogenous thyroid hormone levels. In terms of altering body composition, it's hard to argue that ephedra or ephedrine is more effective. In terms of an anorectic effect from ephedra and the CNS stimulatory effects, one can make a case for ephedra being more effective and rightly so as there is at least one amphetamine-like compound in the alkaloid extracts.
All of that aside, adding ephedra to the current HOT-ROX formula would require dropping out at least one of the compounds due to possible interactions.
Again, the reason we developed HOT-ROX was to have a product which had greater overall efficacy and safety than ephedra products and I think we succeeded. The fact that HOT-ROX and its' related products have been so successful in terms of sales over the years, while other products designed to replace/exceed ephedra products are now off the shelves or were ditched long ago, I think, is supportive of that. Furthermore, I believe the success of the product has opened doors for it to be sold on a much wider scale than any other previous products.
Again though, in terms of psychiatric effects and CNS stimulation, I'd admit that ephedra is superior, but most people simply aren't seeking such a product when it comes to losing fat.
