Hi there ~
I understand your concerns. I believe that smoking
marijuana and MDMA usage are not related to psoriasis
directly, however they may hamper the recovery from the illness. I believe there are many anti itch medications available over the counter as well as medications that are useful when you visit with and get prescriptions from qualified local doctor. I hope you do so as soon as possible as either MDMA or marijuana are not the answers to your problem. Wishing you the very best in recovery.
I hope this helps. Take care of yourself and have a lovely day!
