The psoriasis cream is just another of the wannabe cannabis drugs that have not proven to be anymore effective than a placebo.
The GWP clinical trials which to can follow on their website has shown that Sativex a 50/50 mixture of THC/CBD is no more effective than a placebo in mitigating pain in cancer patients.
Odd how you can follow their clinical trials and read the results but OWCP there isn't anything but more pump BS.
