Is distrusting the MHRA's regulation of e-cigarettes "conspiracy theories?"

Recently on a forum for e-cigarette enthusiasts, a commenter said he "saw no harm" in the move to regulate electronic cigarettes as medicine in the U.K., if what the MHRA was saying about just wanting to have e-cigarette companies "apply for licensing and to make sure the nic juices deliver consistent amounts of nicotine as advertised" was true. Apparently expecting doubt from other commenters that the MHRA was being forthright, the commenter said, "Conspiracy theorists have at it."

How is it a conspiracy theory, I asked? These people have 30 years of lying to the public about tobacco, nicotine and low risk alternatives as evidence they have no interest in telling the truth.
