I am sure that the state is not interested in the legalization of drugs. Addiction is the addiction of the young. It kills first those people whom the government is interested. Who will work and bring income to the Treasury? I think legalization of drugs is only interested in some officials who want to make money. Legalization will bring harm to all.
So all officials are engaged in something poisonous in order to earn money in treasury. Alcohol, cigarettes, drugs, prostitution ... all these are governed by rulers.
Officials earn more on illegal businesses. Let's see what happens for example with cigarettes. Europe has set a very high excise tax on these products. Now everywhere you can buy illegal cigarettes. They bring money to the officials and the police, but the state loses income.
