Why has propoxyphene (Darvon) become an important drug of abuse?

Its availability
Its low cost
In combination with alcohol its effects are greatly intensified
It's not detectable in standard drug tests

The correct answer is: In combination with alcohol its effects are greatly intensified

Propoxyphene (Darvon) has become an important drug of abuse due to its ability to greatly intensify the effects of alcohol when combined. This makes it more desirable for individuals seeking an even stronger high. The other options, while they may contribute to propoxyphene's abuse, are not the main reason for its significance as a drug of abuse. Its availability and low cost may make it more accessible, but it is not the only drug with these characteristics and therefore cannot solely explain its importance. Similarly, while it may not be detectable in standard drug tests, this is not the primary reason for its abuse.
