Hi there ~
I understand your concerns. The dry flaky lighter skin after the use of "recreational" drugs is due to loss of blood supply coupled with poor appetite
resulting in malnutrition
when a person is dependent on a substance for a prolonged period of time. I also believe that you may be able to overcome this problem by being able to go off of the substances by consulting a psychiatrist
that is well versed
in substance use disorders. I wish you the very best in early recovery.
I hope this helps. Take care of yourself and have a lovely day!
