As a conservative, I fully support the legalization of drugs (or at least the soft drugs such as weed). The war on drugs and the ban has only helped the drug mafias and big bankers. If the drugs are made available through government-owned shops, then the drug violence will cease, and the number of deaths from drug overdose will be a thing of the past.
Yes, what we're seeing the world over is some Prohibition Era shit... Just remind them they'll earn money from legalizing drugs, they love taxes.
They are very shrewd. The tax money will go to the treasury, and only a small amount of it can be stolen by the corrupt politicians. On the other hand, if the prohibition remains in place, then the politicians will be able to earn a lot of bribes and commissions, not just from the drug mafias, but also from the big bankers and the pharma cartels.
