I don't agree with this at all, i don't see how you can punish someone who acted within the law in the country that they were in. It is ridiculous... but Thailand did act in a similar way prior to the legalizing (the case of the Dutch guy who was jailed and lost everything in Thailand for legally selling marijuana in the Netherlands springs to mind). Bearing in mind how the Thai justice system treated this Dutch guy will be interesting to see how they respond to the behavior of the Malaysian authorities.
