I have suggested licensing drug usage. In which case it is not up to the government, but rather the user's employer and health insurer to decide if the user can partake in a particular recreational drug and still remain active employees and insurees. Why should the freedoms of individuals be restricted for the convenience of employers and insurers? Staying up too late also affects one's health and job performance; should government also license adults' bedtimes for the convenience of employers and insurers?
Good point.
