I think even if not legalisation then at least decriminalisation is certainly worth investigating.
For those who think that the only preventing people taking drugs is the law, don't understand drugs. You, I or anybody else could go out and buy any drug we wanted if we wanted it badly enough. The reason most people don't is because they don't want to be addicted, they don't want to be drug users, they don't want that lifestyle. They aren't pilara of society kept on the straight and narrow by fear of the law. Equally most drug use isn't prosecuted because doing so is expensive, pointless and wastes resources which could be out towards tackling violent crime. Addictions aren't choices, by the time somebody addicted, particularly to drugs like crack and heroin, the choice to steal and desperation for the next fix isn't in their control anymore. Because they have so little faculty over that choice, trivialities like the law won't stop them doing anything to attain the next fix. And so are absolutely useless in preventing drug use.
If you look at more progressve countries with better programmes and facilities for drug users, such as a bunch of smthr scandi countries we see that most people want to get clean. In these countries the focus being on wellness and recovery, not punishment, this helps users access services without stigma or risk of prosecution.
For less potent drugs like marijuana, decriminalisation and legalisation has proven greatly effective in many countries and has shown to have the ability to generate enormous tax revenue, legalisation also helps to defund organised crime. Legalised drugs are also safer and less likely to contain dangerous chemicals, harder drugs or things like chemical contamination and pesticides.
The war in drugs is a joke, it's already been lost lol.
