My mother has had severe hives come and go for months. No allergies after testing. What could this be. And could she be allergic to her cigarette smok?

In brief: CHRONIC URTICARIA
The cause of hives is unknown in up to 50% of patients! some patients have 'chronic urticaria' which has to be managed with histamine blockers such as zyrtec (cetirizine) and zantac (h1 & h2 blockers).
She should stop smoking for overall health reasons.

In brief: See MD
Chronic hives are a very difficult medical condition.
A patient with hives for more than 6 weeks is categorized as "chronic". Such a patient needs a thorough evaluation to look for unusual causes of hives -- from the very benign to the very serious. As mentioned it is not unusual, however, for no specific cause to be found.
