  Henden also notes that weakness of will seems rationally criticizable in a way that addiction does not, which suggests they can’t be the same phenomenon. Many addicts sincerely try very hard to abstain from using drugs. Though their effort may be insufficient for them to succeed in abstaining, it may nonetheless be sufficient relative to ordinary standards. That is, if someone who was not an addict made the same effort with respect to similar endeavors, it would be reasonable to expect her to succeed. The challenges that face addicts thus seem much more demanding than the challenges that face the average practical agent, including those prone to akrasia (Henden 2016, p. 123–4).
