I've met potheads that have never done heroin, coke, crystal meth, etc, but I've never met a junkie who didn't get started on weed. All crackeads, heroin addicts, tweakers started on weed. Gateway drug and I'm for stiffening the laws.
How many junkies have you met? Alcohol & Cigarettes are normally the first drugs that people take - these are the gateway drugs - and they're legal. Worldwide, 162 million adults use marijuana at least once per year, and 22.5 million use the drug daily. To date, marijuana has never killed anybody, marijuana has many many medicinal purposes and the plant itself is a fantastic resource for making clothes, rope, paper etc.. The war on Drugs has caused far more suffering and deaths than if the drugs were legal.
If you take what's going on in Mexico as a prime example, were the cartels actually run the country and brutally murder at an alarming rate, there is now widespread corruption, also Military intervention to help police the country and the most horrendous crime rate and brutality. It is inexcusable for those in power to enforce what people ingest into their bodies - forcing your beliefs onto others on what they should ingest is Fascist nonsense. I'm amazed that people don't see the inherit violence of such an immoral ideology. Those who support such policies have a tremendous amount of blood on there hands and are responsible for untold suffering.
By criminalising marijuana, you create very powerful criminal organisations, one that operates beyond the law - the ultimate price is paid for by the taxpayer, the legal system and the average user who is incarcerated in an already overburdened jail system. Everyone loses except the Drug Lords!
