Apparently medical students take psudoephedrine like the stuff in solpha sinus etc to stay awake.....
That's the basis for Crystal Meth, Mercenary...Pseudo...
That was all listed out in the Netflix series of 'Breaking Bad' when 'Badger' brought a bag
full of sinus tablets to 'Jesse Pinkman' as pseudo fer his Meth cook in the Winnebago Lab.
Also in the same series the word "
Hippocampus" was used and explained by 'Walter White'
while in discussion with 'Gus Fring' during dinner at Gus's home.
