THCP — the most potent known cannabinoid
Discovered in 2019, THCP binds up to 30× more strongly to the CB1 receptor than Δ9-THC. What does that mean in practice, and can you even own it in Switzerland?
THCP has a longer alkyl side chain than Δ9-THC (7 vs 5 C). Up to 30× CB1 affinity, ~5–10× practical potency of THC. Present in traces in plants, produced synthetically. In Switzerland captured by the generic 'THC isomers' clause of BetmG — de facto illegal.
Why THCP is so potent
The CB1 receptor recognises cannabinoids via their alkyl chain. THC has 5 carbons, THCP has 7 — it fits the binding pocket much better.
As a result, microgram doses are effective. A typical THC dose is 5–20 mg, whereas strong THCP effects appear at 0.5–2 mg.
Effects and risks
Reports describe strong sedative, physical effects with long duration (6–10 h). Frequently reported: tachycardia, anxiety, dissociation.
Without human studies, the therapeutic margin is unknown. Poisonings from THCP vapes are documented in Europe 2023–2024.
Swiss legal status
THCP is not listed by name in BetmVV-EDI, but falls under the generic 'isomers and homologues of THC' clause. In practice authorities treat it as a controlled substance.
For consumers: buying and possession are risky and treated analogous to THC offences.
FAQ
Is THCP legal in Switzerland?
No. Even without express listing, the generic THC-homologue clause of BetmG applies.
Is THCP natural?
Yes, in traces (< 0.1%) in some strains. Commercial quantities are synthetic.
How much THCP equals 10 mg THC?
Roughly 1–2 mg THCP, but variance is huge — self-dosing is dangerous.
Does CannabisClub offer THCP?
No. Neither legal nor quality-acceptable.
