Drugs have no place in today's society , it will surely surely end with nothing good for the entire world
Drugs have their own uses. Even the banned drugs are useful in various forms as painkillers, relaxants, and anti-depression medications. I agree that there seems to be a lot of drug-induced violence going on in this world. But you must understand that banning the drugs and prosecuting the drug users haven't done the trick for the last many decades.
Perhaps they are useful for some diseases, but dosage is difficult to observe when you want more. With legalization, it is unlikely that they will be used strictly for their intended purpose, it is better not to take risks.
