Not Ethyl, Jim.

For drinkers of IPA we have hospitals.
Actually, I don't know what effect IPA has when ingested*.

The IPA concerned is already notionally 99%+ and has no emetics or
similar added, so distillation is unlikely to improve its
comestibility.

http://en.wikipedia.org/wiki/Isopropyl_alcohol

Isopropyl alcohol and its metabolite, acetone, act as central nervous
system (CNS) depressants. Symptoms of isopropyl alcohol poisoning
include flushing, headache, dizziness, CNS depression, nausea,
vomiting, anesthesia, and coma. Poisoning can occur from ingestion,
inhalation, or absorption; therefore, well-ventilated areas and
protective gloves are recommended. Around 15 g of isopropyl alcohol
can have a toxic effect on a 70 kg human if left untreated.[14]
However, it is not nearly as toxic as methanol or ethylene glycol.
Isopropyl alcohol does not cause an anion gap acidosis (in which as
lowered blood serum pH causes depletion of bicarbonate anion) unlike
ethanol and methanol. Isopropyl alcohol does however, produce an
osmolal gap between the calculated and measured osmolalities of serum,
as do the other alcohols. Overdoses may cause a fruity odor on the
breath as a result of its metabolism to acetone, which is further
metabolized to produce the nutrients acetate and glucose.[15]
Isopropyl alcohol is oxidized to form acetone by alcohol dehydrogenase
in the liver.

but

Isopropyl alcohol dissolves a wide range of non-polar compounds. It
also evaporates quickly and is relatively non-toxic, compared to
alternative solvents. Thus it is used widely as a solvent and as a
cleaning fluid, especially for dissolving oils
