u get carded here for buying a can of air. thanks to all of the huffers. i went to buy a can of fellowes, air duster along with some other items and check license popped up. the cashier stopped the scanning and held the can with a death grip until i gave her my license. stupid huffers, u cant buy much of anything with a propellant in it. u r limited to 3000mgs of pseudoephredine a month in my state. the drug is sold otc at the pharmacy. each time u buy it, u have to show your license, they enter it into the computer, then u sign for it. kinda sad, but it beats having your next door neighbor blow their house up.
