Well at least the second page of this argument got a little better.
Yes, it should be allowed to be tested with. Illegal drugs have been used in all different parts of different societies for medicinal purposes, cocaine was given to US soldiers during the first world war and cocaine was even in the drink coca cola (around 1940 I believe) to heighten their senses and keep them alert.
That nasal decongestant you use? Well that's basically speed, or at least a polymer of amphetamine. Yes, nasal decongestant is amphetamine.
Those pills your nan uses to control her heart? Yes, why they are your grandad's viagra (beta blockers and viagra are essentially the same, I know it's not illegal but I'm just making a point)
So out of all these, weed is relatively harmless really.
Secondly, it should be decriminalised for personal use. It will free up the courts and the prison's for people who actually commit serious crimes.
I also think there's a good argument that the government should sell it, the same way it does tobacco or the same way Amsterdam used to (cry cry). The extra money from weed tax would certainly help propel this country out of the recession. Not to mention then that it will cut street dealing and associated crime, also because it would be regulated by the government they can tax it at whatever they decide. Also, kids won't be tempted to try something that is a legal drug and less stigma around the subject means people can be properly educated and people with 'addiction' problems can seek the help they need without fear of prosecution.
If the government did legalise it though, they should also force MacDonalds to deliver just like they do in other countries...
