I think the Government commercial depicting an egg frying was pretty much the most substantive piece of evidence that the government possessed on the effect of drugs on the human brain.
IMHO, within a century the entire anti-drug regime will be seen as having been an enormous criminal conspiracy to maximise the revenues of the conscienceless grandees of the drug bizness. After all, who benefits financially from the current system? Criminals. What keeps prices high and entry costly? Why, taxpayer’s money spent on “fighting the drug dealers”
The lawyers, police, and prison and social service personnel catch a few crumbs and grab a little grease from this bizness, but the steak is eaten by powerful and protected cartels, who operate with apparent impunity wherever they go on this planet.
The money must flow to very high stations in life indeed for such immunity to persist.
IMO the Medical Marijuana movement has complicated the inevitable process of moving towards more rational views about cannabis use both medicinally and recreationally. It has succeeded in softening the law in many places for certain circumstances of possession but it has disingenuously, and IMO, intentionally confused the truth about both medicinal and recreational use.
There is indeed some crossover just as alcohol and caffeine are simultaneously used both socially and medicinally. But the MM movement is almost as guilty of misleading propaganda as the drug warrior element in the government has been.
