It is the policy of the Congress that certain persons charged with or convicted of violating Federal criminal laws, who are determined to be addicted to narcotic drugs, and likely to be rehabilitated through treatment, should, in lieu of prosecution or sentencing, be civilly committed for confinement and treatment designed to effect their restoration to health, and return to society as useful members.

It is the further policy of the Congress that certain persons addicted to narcotic drugs who are not charged with the commission of any offense should be afforded the opportunity, through civil commitment, for treatment, in order that they may be rehabilitated and returned to society as useful members and in order that society may be protected more effectively from crime and delinquency which result from narcotic addiction.
