It is far more likely that Mr. Hoffman died of an accidental overdose than suicide. If it was suicide then the drugs are a moot point, there are many ways to commit suicide without drugs. But assuming it was an accidental overdose, then our society and the Drug Enforcement Agency are far more to blame for blocking Hoffman and countless others from getting the safe legal drug treatment they need. Most overdose deaths are simply a matter of the user mistaking the purity and strength of the drug they are taking. This could be easily avoided if Doctors were able to prescribe pharmaceutically pure versions of the drugs used in a controlled manner.
The DEA (Drug Enforcement Agency and FDA (Food and Drug Administration) must allow the AMA (American Medical Association) to be in charge of the 'drug issue' by giving doctors access to these drugs for treatment purposes.
If the FDA reschedules coca, poppy and pot and derivatives, so that doctors have access to these drugs for treatment to addicts, then we will save many innocent lives and be able to make quick progress towards deflating the South American and Afghanistan drug empires.
Also, with the present prohibition we are dooming our civilization by empowering Drug Lords like Arab Kings. The Drug War funnels money to the underworld and is the funding mechanism for major terrorism and rogue government leaders.
Our confused policies have been a cancer on all of the Americas for decades. We must change, Philip Seymour Hoffman could be alive today.
