Neither of the drugs he mentioned are research drugs... benzedrex (aka propylhexedrine) is an over the counter allergy drug (like a Vicks inhaler except it actually gets you high if you consume it - by the way, to anyone reading, you should NEVER eat the cottons, if you must do it, instead soak the cottons in acidic liquid, like a soda or Snapple or something... swallowing all that cotton can cause intestinal blockages), and ephedrine is well-studied. I would not say that stuff like meth or amphetamine is any safer. Nor should this guy be ridiculed for coming here for help for having a problem with them.
To the OP, you'll be fine. Fortunately, stimulants are not physically addictive. You'll feel tired and depressed for a little while. The most important thing is to find something besides drugs to focus your time and energy on.
