The street name for Dexedrine was called Speed when I was young. College kids used it primarily as a way to pull and all-nighter. I also think it is/was used commonly by truck drivers when having to drive all night.

It had also been used as a pill to help with obesity.

As far as how you feel physically, taking a pill will not do you any harm with one. It is more whether you like feeling as if you had consumed a WHOLE bunch of coffee!!

As far as addiction, I highly doubt you will become susceptible. You are old enough to be in control. THAT is my assessment of you, Twink.
