Marijuana should have been legalized everywhere decades ago. Pot smokers generally aren't hyped up like meth users are. Some people cannot handle drugs of any sort, but stopping them from using is near impossible without intervention and desire. Money is made from all drug sales, and that won't stop even if you you target the main suppliers, like they do. The war won't stop anyway because much of the drugs are made, and grown, in country areas away from civilization, and are protected by cartel members with weapons, and a lot of police are involved protecting them. Like was mentioned, rich like drugs also, especially cocaine, and that again is protected by crooked law enforcement in every country, because money is to be made. Some drugs should be legalized, most shouldn't. Drugs cause changes in the brain, and some who use them get violent. Alcohol, another drug which is legal, kills far more than any other daily, and there are laws about alcohol use that are ignored, like driving under the influence. Doctors kill thousands of people a year over prescribing opioids, drugs that are extremely strong and very addictive. Where there's money to be made, illegal sales will continue, as will corruption. People love drugs. The problem is that they, like sugar, is addictive and it causes that addiction to continue. Penalties should fit the crime. Users that aren't hurting others should have rehab as an option. People selling drugs to children should get maximum penalties. People who kill others in their search should either get death, of life without parole. People are weak, but some are easily addicted, unless they have strong will power and can stop themselves.
