Amalgam is safe too. Just ask any dentist that uses it.

Dentists, dental assistants, and nurses have really high rates of prescription drug misuse/abuse also. Just check any state medical license database. Lortabs are more popular than pot for those who have access to the prescription pad. They're safe, can't you tell that by the fact that so many of them are successfully employed under the influence? I cannot figure out what all the fuss is about.
