Is this fair?

I have temporarily changed the topic of my blog but this video I found in NY Times just made me mad.

Marijuana is legal in some states of the USA, like California. The war on drugs, sponsored by the USA, has caused so many negative effects in countries where marijuana used to be grown, deaths, herbicide spreading over crops ...

The link to the video is http://video.on.nytimes.com/?fr_story=b7e4529b7a3ac6b3ffbba2deeb447b5324e49b92

And apparently, some doctors write the prescription with the suggestion of their patients and "patients" go and buy the weed and smoke it...

What's next, legalization of cocaine when people in the USA learn how to grow coca indoors?

Unbelievable, this double moral...
