started out deliberately to hook the poorest in our nation to 'make them happy about living in poverty' by keeping them high, especially during prohibition when booze was outlawed and only the rich were able to pay the price for bootlegged alcohol for their speakeasies (sorry SE). Before that, booze was the 'high' of choice for poor people to escape their societal issues....mainly in the black communities.
Governments and cops were on the payrolls of most drug and booze 'dealers' especially in the depression years.
Then the upper echelon population started buying and since they could afford it, it was purchased in larger quantities but the poor were so hooked already that many turned to crime to pay for their addictions.
This was all done deliberately to the poor mainly to keep them 'in their place' and all of a sudden, the elites 'discovered' it and the demand grew to such an extent that cartels came into being and they couldn't get the crap here fast enough.
Look at the billions of dollars seized by the governments today...not just in drugs that are eventually (but not always destroyed), but in real dollars and properties. And they have free reign to seize anything even suspected as being 'drug money' or purchased with 'drug money'. For instance...our area is huge with Christmas tree farming (my property is rented for that purpose right now). Many of these farmers deal in cash....large amounts in the tens of thousands....one of them was stopped by the highway patrol on a route that is normally used by drug mules/traffickers and the car (pretty high end) was searched. The money was found, the car was seized along with the cash, and the man and wife were arrested. It was eventually in a courtroom where they were able to prove the cash had nothing to do with drugs....found innocent, charges and records purged....BUT it was ruled that the cash and car could be kept by the government. No explanation, and no appeal occurred because the people decided that an appeal would cost far more than what they were losing/having confiscated. I guess Florida hadn't met their quota for seizures that year. Personally, I would have sued for false arrest and imprisonment and theft of property. Since they were a black couple, some ACLU lawyer probably would have taken the case for them.
