FAQ
Is Delta-8 legal in Switzerland?
No — Swissmedic treats Delta-8 like Delta-9. Products above 1% total THC are controlled substances.
Why is Delta-8 popular in the US?
Because of a loophole in the 2018 Farm Bill allowing CBD derivatives, from which Delta-8 is synthesised. Many US states have since closed the loophole.
Is Delta-8 safer than Delta-9?
Delta-8 causes less anxiety, but safety depends mainly on the purity of the synthesis — solvent residue scandals have hit the market.
