It's a very specific way of saying "addictive," which I appreciate. Different drugs are addictive for different reasons, and redosing is triggered by different physiological inputs.

Compulsive redosing refers to a short-term addictive quality. It feels good so you take more.

Addictive can mean a lot of things. Opiates have agonizing, long-lasting withdrawal effects that can trigger redosing over the course of months or years. That's also a meaning of "addictive" but one that is intentionally not included by the author's wording.
