Not the drugs are baned, just thinking differently and be proud for it!
Clearly you can establish that the use case of drugs dosent get reduced when you make it illegal in law, same is for every human behavior. You can find many killers and rapist when there is execution as punisment for it. Because the reasons for any choice of act and behavior are not disappeared when you strive against its symptoms.
And moreover using drugs are not objectively wrong by moral order of society, hwo do you might damage with it? Just pushing it to an underground style of living makes it related to some bad behavior like thivery or violence. And the rulers knows that exactly like i know. So you can buy it now in almost any country in the world, use it in proper conditions, hidden, away from your parents, even if a big number of people use it and knoes that so much people think its ok to use it. Not me is carrying all that stuff, hundreds of kilos of drugs transporting with ships and trucks to metropole. If the illegal status till now has done no difference by its use quantity, why you think they did spend so much energy to fight it?
Well when something is illegal its costs more and the biggest share goes to same click which makes laws. Thats a simple fact that everybody knows. But i think there is more than that. This effort is about to prevent that the consciousness from drug experience come to light and teach fearless the society about, what isnt this life and how it can be instead of this meaningless hustle and bustle. When you consume for example psylocibin mushrooms, you know that the data handled by your brain is the same before you did eat mushrooms, but the result is something else. Now, thats the main danger to them, which makes them try to separate the population, which goes after the secrets of experience and dont have courage to make it. This way the drug users are convicted to live it in their society and the daily praxis habits banished to illegal hustle. It becomes an illegal lifestyle, even if has to tell more than swinging numbers of prices in derivative markets.
We should legalize all the herbs of mother earth, no doubt. Even they cant tell clearly what life is, but they tell all about what it isnt, when you observe it with the eyes of father Peyote. I'm sure after all, its nothing to do with pumping the fake indicators. For more, you should look yourself, i dont want to spoil :)
