Yeah, 95% ethanol can get you stupid drunk in a hurry.  On the 
other hand, absolute (i.e., > 99% ethanol) has additional risks.  

Ethanol (EtOH) forms an azeotrope with water, so 95% is the max 
purity that can be achieved by typical distillation.  Getting to 
higher concentrations requires special techniques.  Historically, 
this was done by including benzene in the distillation to disrupt 
the EtOH/water affinity.  This process typically leaves traces of 
benzene in the resulting product.  Indeed, the EtOH I pilfered 
from the lab tasted horrid, even mixed with orange juice.

More recently, molecular sieves are used to make absolute ethanol.  
Even without trace benzene there are risks--because of the high 
affinity between EtOH and water, if you dring neat absolute EtOH 
it will suck the water right out of contacting tissues.  Not good.
