Dear 100 Hour Board,
Regarding the purchase of products containing ephedrine in Board Question #53593:
Whether anything happens from buying too much varies GREATLY by state. As a brief example, take a look at this news story out of Indiana that talks about a grandmother who purchased two boxes of cold medicine in a week. This violated state law (purchasing more than 3.6 grams of pseudoephedrine in one week) and she is being charged with a class-C misdemeanor (carrying a potential sentence of up to 60 days in jail and up to a $500 fine).
Laws vary by state regarding the purchase of such cold medicines. Know your state laws before purchasing!
