Rob,
Oh, I've no doubt that this incovenience will only slow down a determined cook just a little, and yes, it is an incovenience for the non-meth-cooking public. I tend libertarian, but in this case, it's a worthwhile step - even if it only raises awareness of meth abuse, which might lead to more police tips about questionable behavior. The reason for the ID is to leave a crumb trail for police when someone smurfs the stuff at a string of stores to get the amount needed.

edit: I'm 35 and still(!) get carded semi-regularly. It cheers me up.
