Drug Prohibition = A law making the production, sale, or use of
a drug a criminal offense.
Legalization/Decriminalization of A Drug = Repealing a prohibition
on the drug.
Utilitarian = One who holds the view that government should try
to maximize total utility (i.e., happiness).
Libertarian = One who holds the view that the only legitimate
role of government is to protect rights to equal liberty.
In class we distinguished various types of Libertarian view. It
is useful to give them names:
Unrestricted Libertarian = A Libertarian who holds that one should
be permitted to give up one's rights.
Restricted Libertarian = A Libertarian who holds that the rights
to equal basic liberty are inalienable; one should not be permitted
to give them up.
We also added another type of view, which I think we should classify
as another type of Libertarianism:
Caveat Emptor Libertarian = A Libertarian who holds that even
laws that are intended to promote informed consent (e.g., laws
requiring warnings or other information) are violations of rights
to equal liberty (either the rights of the person required to
provide the warning or information or the rights of the person
required to be exposed to it).
Classical Conservative = One who holds the view that one of the legitimate roles of a government is the moral improvement of its citizens. (Analogy to the role of parents.)
In lecture, we also added:
Mill's Harm-to-Others Principle:
"That the only purpose for which power can be rightfully
exercised over any member of a civilized community, against his
will, is to prevent harm to others." 
Paternalistic Reason for a Restriction on Liberty: A justification
for a restriction on liberty that is based on preventing physical,
psychological, or moral harm to (or promoting the physical, psychological,
or moral good of) the person whose liberty is being restricted,
against that person's will.
Mill's Arguments Against Paternalistic Interference: The state
should not intervene to prevent a person from using drugs, if
the only harm is to the user him/herself.
Compare Mill's discussion of gambling, drunkenness (the Maine
Law prohibited alcoholic consumption), and poisons.

Others are Directly Involved
