Good you didn't get 15 years of forced labour (
see this thread), or be executed like they'd do in Singapore or Malaysia, even for a bit of hemp...
These Asian countries have really no idea of why the West started banning drugs, but copied them anyway just to look "modern" and now end up being criticized for human rights abuse, etc. because they can't think by themselves. Drugs are prohibited to protect people's health, so it is utterly illogical to execute someone or send them to jail for years until their health and mind deteriorate completely, because they "possessed" some relatively inofensive cannabis. And during that time millions of Japanese salarymen get drunk till they throw up in the subway almost every night.
