[|Human|] CAN LONG TERM METHAMPHETAMINE ABUSE BE THE REASON I HAVE PSORIASIS AND PSORIATIC ARTHRITIS?
[|AI|]  Hi; Psoriasis is an autoimmune skin disorder it comes on due to some trigger like stress mental/physical ;odd working conditions & as sudden impact of some bad news like death of a close one;or accident & occasionally aggravated because of some allergic thing. Psoriatic arthritis is a complication of it. Now the big question is whether you had psoriasis before abuse of Methamphetamine. If yes then you see the reason is not abuse ;& if you did not have before then it can be because of abuse. In any case even if Methamphetamine abuse is not the cause of Psoriasis ;it will always act as the aggravating factor, so please discontinue abuse of the said Chat Doctor.  Thanks
