Dr. Mark Lewis explained that all commercial HHC is made by chemical conversion of CBD under acidic conditions followed by hydrogenation. European markets sell HHC products that pass roadside mouth swab tests despite producing psychoactive effects. Dr. Lewis holds a patent on HHCA (hydrogenated THCA).
