Good grief. Nothing like news that's been filtered two or three
  times.

  Here it is more in context: [took a bit of searching]

  If you can use 5th grade Inference skills, he's primarily
  talking about NARCOTICS and inferring about the use of Methadone
  to treat NARCOTIC addiction.

  Marijuana is not a narcotic. In the USA we're very specific to
  refer to recreational drugs as meaning pot-only. Also, he was
  speaking to the Roman equivalent of the DEA.

  Let's imagine if he specifically stated, "Except for the poor
  little pot plant - that's fine" and kept the rest the same, or
  was specific about referring to methodone and heroine/opium,
  which are the primary narcotic addictions that seem to be a
  problem in the drug trafficking trade... would you still have a
  problem with what he said?

  *Let me state this in the clearest terms possible: the problem
  of drug use is not solved with drugs! Drug addiction is an evil,
  and with evil there can be no yielding or compromise,* Francis
  said.

  *To think that harm can be reduced by permitting drug addicts to
  use narcotics in no way resolves the problem. Attempts, however
  limited, to legalize so-called *recreational drugs* are not only
  highly questionable from a legislative standpoint, but they fail
  to produce the desired effects.*

  The pope said drug use was fed by a *deplorable* international
  commerce that put the lives of adolescents and young people in
  danger. *Faced with this reality, I can only manifest my grief
  and concern,* he said. === I'm not saying that the Pope is "for
  pot" or "against pot". But going by all the context, it sounds
  like he's talking about the heroin/opium trade, which is a HUGE
  problem and can leave people destitute.
