California s Office of Environmental Health Hazard Assessment declared on Friday that the smoke from marijuana is carcinogenic and therefore falls under the purview of the state s Proposition 65, which requires all products with suspected carcinogens to carry warning labels.
Prop 65 is an unproductive law which provides no health benefit except to lawyers, says ACSH's Dr. Gilbert Ross. It has done nothing but encourage California s thriving bounty hunter litigation so that companies can be sued for not using the right warning labels.
