I am currently 17 and a sohphomore in college.  I am at the point where
I need to pick a definite career path and stick with it.

I am seriously considering becoming a pharmacist, and would like to
know ahead of time if it will require that I take random drug tests.

I am also considering chemical engineering and a couple others.

Also, any advise on choosing careers would be much appreciated.

Thanks in advance!
