You are correct. Indeed, it is far beyond mere addiction for smokers. It is a matter of hard-core heavy duty BRAIN DAMAGE. Medical science has shown this for CENTURIES, http://medicolegal.tripod.com/preventbraindamage.htm since at least August 1603 . The addiction aspect has been reported since at least the year 1527, http://medicolegal.tripod.com/tobaccoaddiction.htm Smokers also are documented to suffer from disproportionate mental disorders, http://medicolegal.tripod.com/preventmentaldisorder.htm
Deleterious cigarettes are illegal in Michigan, http://medicolegal.tripod.com/milaw1909.htm There is no right to use an illegal substance.
The term "smokers' rights" refers to their right to sue their pushers for tobacco-caused injuries, http://medicolegal.tripod.com/dangeroustobacco.htm (and the right of their estates to sue their pushers, once they are dead).
Constitutionally, rights exist to (a) put out fires and (b) pure air, as per anti-nuisance and pro-safety legal principles, http://medicolegal.tripod.com/pureaircases.htm Such rights of nonsmokers date back thousands of years and are continually upheld.
When smokers claim otherwise, remember their sad state, brain damage, etc., impairing reasoning and comprehension. See details on tobacco's adverse brain results and symptoms caused, at http://medicolegal.tripod.com/preventbraindamage.htm
