I'm just going to copy and paste what I put on another similar topic, it might not be 100% relevant but it certainly expresses my views on this matter:
I don't condone drugs, or drug use, I've used them myself (only weed, used to be quite regular) and have nothing against them. When you say drugs, you really are lumping together an enormous amount and hammering it into a small and stigmatised pigeon hole.
Weed. Reportedly more carcinogenic than Tobacco, but consumed in much lower quantities, not chemically addictive. When people get addicted to it, it is to fill a hole in themselves, they become habitually addicted because they don't know how to function without feeling high. If it wasn't cannabis it would be something else. This isn't a plus point but it raises a much more important issue. The highest percentage of people habitually addicted to weed are from broken homes, bad backgrounds, poor education, abusive/negligent parents. The real issues that need to be addressed are the failings in our society that cause people to turn to weed in the first place. They are the same issues that turn people onto constant alcoholism and harder substances.
It's like the fox hunting debacle in Great Britain, the ruling party use issues such as this to pull attention away from their more devastating failures. When governments need to be seen to be doing something, they go the easy route: The War on Drugs. Not the War on shit teachers, not the war on shit schools, not the war on bad parenting, poorly run state welfare, child abuse, health care, employment etc etc. These are issues that they are either too scared or too incompetent to solve for fear of law suits, or spending billions of tax payer money on some hair brained scheme that is doomed to fail. The fact is modern governments are so weighed down under the mounds of bureaucracy, they simply don't have the ability or the courage to tackle these problems.
Drugs are like sex offenders and murderers, they're "evil", no one will disagree or find contention with the aims of a "War on Drugs" and it is much easier to produce positive, albeit frankly futile, results.
"Look here mindless simpletons, we busted a small farm of marijuana that was poisoning our society with its evil ways! It only took months of police resources and thousands in tax, but our work is done! Gaze upon our crime busting glory! What's that you say? Knife/gun crime on the rise? Child Abuse and failing foster care systems? Nonsense, it's the War on Drugs that matters!"
It is a proven fact that recreational use of weed is much less dangerous than smoking tobacco or alcohol. It is impossible to Overdose on THC by smoking Marijuana. It's medical uses are numerous and powerful. Its bi-product is Hemp, a low cost, low maintenance - high yield substance that has multiple uses: Bio Fuel, Clothing, Lubricating Oils and perhaps most significantly - paper. If it was legal it would be the ideal crop for 3rd world countries to produce. Bringing industry, jobs and prosperity to impoverished countries.
When it comes to pharmaceuticals, people are woefully ignorant. Medicine is really lovely word for drugs isn't it. When you think of medicine you think of running 3 miles in 10 minutes, a cancer free, golden haired pillar of society, running free and healthy thanks to medicine. Some of the shit that gets prescribed to the general public on an alarmingly regular basis, all legal, all untaxed, all at huge corporate profit, is horrifying. Anti-depressants, anti-psychotics, mood enhancers; all thrown at men, women and children like fucking jelly beans and no one bats an eyelid.
The main reason why Marijuana is failing to be legalised is because more established corporations that invest in timber and other competing markets put extreme pressure on their governments to think otherwise, and in some cases vilify it's production.
If a 9 year old smokes weed, is it the drug producer's fault, or the fucking incompetent parent's fault? The fact is if the government regulated its use, much less of it would find its way into children's hands. Yes there will always be a black market for things, but your average dealer would never, ever be able to compete with a legalised distribution chain. Shady dealers that sell dangerous weed to young people would cease to exist.
Now when we talk about things like: cocaine, heroin & other opiates, Meth, crack, Amphetamines. Yes these are all, unarguably, terrible things, but they're increasingly wide spread use is at its core, a child of the failures of our society and its governing bodies. People really need to educate themselves before ranting and raving like mindless automatons about Drugs, be specific.
What are drugs good for? Well the Beatles, creators of modern music as we know it, if they weren't high as the bloody Hubble Telescope, I'm the arch-angel Gabriel.
