Rick Simpson oil - a few questions!!

Hi there!! I have psoriasis and excema all over my body ! Applying this topically would cost way too much. Any suggestions???

Also, who is legit that I can order from? Why can’t I order from Rick Simpson himself??

If I take it orally, when do think k may see results? I don’t want to keep taking it because we get randomn drug testing at my job, but I should be ok if bi start soon and stop taking it within a month. How long does it stay in your system?

Any testimonies of it healing Psorasis and excema ?
