As most people know, true opiates such as morphine and hydrocodone are highly addictive drugs because they contain narcotic components. In comparison, Tramadol is a non-narcotic medication even though the effects it produces are similar to narcotics. This is the primary reason many people still question the classification for Tramadol as being a narcotic drug or not.
Armadillos do carry diseases. In fact, one of the most common diseases that are often found in armadillos is leprosy. The link between human infection and armadillos has not yet been heavily tested, but it does still remain a risk.
There are six living sloth, four anteater, and 20 species of armadillos. A recent study confirmed that the Andean hairy armadillo (Chaetophractus nationi) is a synonym of (i.e., the same species as) the screaming hairy armadillo (C. vellerosus), which reduced the number of extant armadillo species from 21 to 20.
