How do smoking and drinking alcohol affect psoriasis?
Both smoking and alcohol consumption have repeatedly been shown to make psoriasis worse. Smoking in particular has been shown to trigger a form of psoriasis called palmar plantar pustulosis. This variant of psoriasis presents itself as red and white bumps mostly on the hands and feet. If you are trying to quit smoking and are considering using a nicotine patch, consult a dermatologist first. Nicotine patches can aggravate psoriasis. Also, alcohol may not only prevent treatment from being effective, it may cause serious side effects when mixed with some psoriasis treatments.
