I know a cocaine junkie. Quite a solid uncle with money, though old-fashioned, prefers to take the staff personally from the dealers. There. He always gets dimych in addition to coke. I asked him, why do you have to be a dime? Can't you get coke without it? He replied that any substance without dimych is just a waste of money. Absolutely any substance acts much better with dimych. Make your own conclusions.
