Uh oh...I'm about to get flamed here Im sure, but I DEFINITELY think this is possible. Ephedra has been compared to amphetamines in many studies. I was on it (Dymetadrine Extreme) for 6-8 months and coming off it was HELL. I think actually becoming "addicted" to it would depend on the users personality. Some have addictive personalities and get hooked easier than others. Upping your caffeine intake when you go off seems to help a lot of people.
