It is a natural curiosity, yes, but Trimpey leaves that out of the books, at least the ones that are based on AVRT. The assumption is the reverse of most disease theories, including psychological disease theories. Drugs make you feel good, and if you take them for long enough, your body will necessarily adapt and a perverted survival drive (the Beast), similar to one's sex drive, only more potent, will eventually be born.
In other words, drugs cause addiction, although there is mention of gambling and other vices.
