TOKYO - Japan will criminalise cannabis use and legalise medical products using substances derived from the plant under revised laws that will take effect on Dec 12, the health ministry said on Thursday.
While the possession and cultivation of marijuana are already banned in Japan, the country will prohibit its use as well, setting a prison sentence of up to seven years for violation.
Ok, so that clears that up.
Can’t be arrested for smoking if your buddy holds the bong for you I guess
