Principles of Responsible Cannabis Use

I. No Driving

The responsible consumer of cannabis does not operate a motor vehicle or other dangerous machinery while impaired by cannabis or - like other responsible citizens - any other substance or condition, including some medicines and fatigue. Although cannabis is said by most experts to be safer than many prescription drugs, responsible cannabis users never operate motor vehicles in an impaired condition. Public safety demands not only that impaired drivers be taken off the road, but also that objective measures of impairment other than chemical testing be developed and used.

II. Set and Setting

The responsible cannabis user will carefully consider his or her set and setting, regulating use accordingly. "Set" refers to the consumer's values, attitudes, experience and personality. "Setting" means the consumer's physical and social circumstances. The responsible cannabis consumer will be vigilant as to conditions - time, place, mood, etc. - and should not hesitate to say no when those conditions are not conducive to a safe, pleasant and/or productive experience.

III. Resist Abuse

Use of cannabis to the extent that it impairs health, personal development or achievement is abuse, which is resisted by responsible cannabis users. Abuse means harm. Some cannabis use is harmful; most is not. That which is harmful should be discouraged; that which is not, need not be. Wars have been waged in the name of eradicating "drug abuse," but instead of focusing on abuse, enforcement measures have been diluted by targeting all drug use, whether abusive or not. If Marijuana abuse is to be targeted, it is essential that clear standards be developed to identify it.

IV. Respect Others' Rights

The responsible cannabis user does not violate the rights of others, observes accepted standards of courtesy and propriety and respects the preferences of those who wish to avoid cannabis entirely. No one may violate the rights of others, and no substance use excuses any such violation. Regardless of the cannabis' legal status, responsible users will adhere to emerging tobacco smoking protocols in public and private places.
