I have spent 25+ years of my life providing ID and signing to buy laboratory equipment and chemicals so that some moron won't make crack pipes. I have news for you. I have a neighbor who makes drug paraphernalia (lovely stuff really, qualifies as art glass). He gets exactly none of his supplies from places where he has to sign for them. I suppose that you could regulate the sale of colored Pyrex glass and inconvenience all of the art glass folks as well in your quest for a drug free society.
Regulations only annoy the law abiding but they do provide good government jobs for union hacks. I suppose that there is some social good to come of it.
