illegal to purchase or carry in California (along with most western states) because of the many meth labs in the area that use it as a base ingredient (so i hear)
however, on the east coast you can but it OTC at any mini-mart chain or gas station.
personally i find it to be a big help when going thru hydro & other holidays. it gives you some energy & your body doesn't hurt all over when taken 1 or 2 at a time.
conversely ~ when taken too often they can make you paranoid & a little koo koo.
my question is: what other bad effects do they have on the body???
