Is THC-P legal in Japan?
- Legal status
- THC-P (tetrahydrocannabiphorol) is a Designated Substance (指定薬物, shitei-yakubutsu) under the Pharmaceuticals and Medical Devices Act — the MHLW named THC-P in the 2023 cannabinoid wave that designated THCV, THCB, THCH, THC-P and THCjd, prohibiting non-medical handling. This is separate from cannabis (prohibited) and from the Cannabis Control Act's THC rules. No death penalty.
- Consequences if caught
- Manufacture, import, sale, possession and use of a designated substance outside permitted uses are punishable by up to 3 years' imprisonment and/or a fine up to ¥3 million (up to 5 years / ¥5 million if done as a business).
- If prescribed or medical
- No consumer or medical market; designated-substance status leaves only strictly controlled medical/scientific use.
- Documentation
- Do not carry or import THC-P vapes, edibles or distillate; they are seized as designated substances.
