I don't take drugs, personally I've never liked the feeling of being "high" but thats me, more power to people who love it.
Drugs should be legalised, why? Because as with everything else we attach a stigma to, it just encourages more people to try it because it must be cool.
Pretend sex doesn't happen, end up with kids having sex and underage pregnancies, open and frank discussion about sex prevents kids getting into trouble. Criminalise drinking and you had the exact same amount of people drinking as when it was legal, just a MASSIVE organised crime side providing the booze AND it couldn't be taxed.
Legalising drugs, despite what retarded politicians think, won't increase drug usage dramatically, it will ONLY change the numbers of people who admit to taking them.
But what are the upsides, there would be no crime involvement in drug production or distribution, so you wipe out lots of gangs, deny an entire area for youths to move into, drug dealing and so on, it simply won't exist anymore. Why would you buy coke for, whatever £50 a gram, when you can get pharmaceutical grade stuff at £10 a gram from a verified source legally? You wouldn't is the answer.
You can produce the stuff safely, without ANY of the smuggling, losses, hiding/dealing costs it would be a 50th of the cost, which means the same addicts who mug, rob, steal and hurt people to get money to feed their addiction, could get a reasonable amount for next to no cash so simply no need for addicts to turn to crime either.
Theres less problems with the source, kids taking E and finding out its been cut with rat poison, because people can get drugs, you get less of the very dangerous "designer drugs" that people manufacture and release without any knowledge of their safety.
Legalising drugs would remove so much crime and violence from our society, anyone that argues against it is completely retarded.
The people who get into a bad situation with drugs, will be better off, people who don't take drugs will be better off, the only people worse off, are criminals who lose a source of income.
Even though weed is plenty cheap enough and all but a tiny handfull of people I've met in my life have tried it, not that many people smoke it regularly, this idea that everyone will just be high 24/7 if drugs are legalised is just plain stupid. Most people still wouldn't take drugs, a few more people would simply be more open and honest about trying it, so would be less likely to hide a gradual problem developing which means getting help to prevent a serious addiction before it gets bad is more likely.
This is all ignoring the fact that 100's millions gets spent on drugs a year, billions worldwide, and it could all be taxed and redirected into providing better healthcare and schools, rather than sitting in criminals pockets.
