Longer lasting cannabinoid

[rotovap5002]

Hi i tried 5c and 5f and they both last for only around 30 minutes. Can anyone recommend of another cannabinoid that lasts for at least an hour and a half or so?

JWH-018 will work for 1-1.5 hours

Yeah that i know, but its hard to get jwh kits.
Was wondering about mdmb-fubinaca, i read that it lasts for 150 minutes on a scientific paper
