A single marijuana cigarette has the same effect on the lungs as smoking up to five cigarettes in succession.
” I noted in your “health” piece that you stated that “smoking marijuana is more harmful than smoking five cigarettes”. This is based on what evidence? How do you define “more harmful”? It should be noted that five cigarettes represents less than 20% of the consumption of the average cigarette user while any marijuana user who consumes any more than one joint per day is mostly dysfunctional.
It never ceases to amaze me whenever a mainstream media outlet publishes reports on any illegal drug as legitimate. Which version of the street drug is used to determine this harm? Any legitimate study of drugs always uses a standardized version of the drug studied. You can’t do this with a street drug – unless it is made legally available where quality and potency can be controlled. It can only be done with a legally available drug with legal users. Otherwise you taint the result with unregulated drugs and criminals and any result involving adverse selection is never anywhere near accurate”.
SO WHAT, is it worth having harsh prohibition laws that criminalize cultivation, manufacture, transporting, possession, and sale of this product. While we create a violent marketplace, imprison our mentally ill, lie to our youth. Fill our treatment centers with those with no interest stopping using the substance nor should they. Last, but the most important, destroy our constitution trying to stop these activities
