The article is clearly anti-marijuana from the first sentence, but John Arnold got off lightly after having his house raided. Arnold claims that he smoked marijauana in order to kick his heroin addiction.

John Arnold, 42, walked free from court, despite being nabbed with 41 plants and sophisticated growing equipment after a raid on his home.

Just a few months before, another cannabis grower got six months behind bars when he was caught growing a farm which contained just seven more plants.

I think this is interesting as it shows judges are fairly lenient towards pot. If this had happened to say, a ketamine dealer (also a Class C drug in the U.K.) I doubt he would have gotten off so lightly.
