A complete ban had been imposed on sale, manufacture, storage and distribution of tobacco products like Gutka, Kheni and Pan Masala in the state from Gandhi Jayanti, an official spokesman said.
"A large number of customers are asking for Gutka whose sale has been banned now," said a shop owner on the Mall Road here.
The state government had taken the decision to ban Gutka and other tobacco products on July 13 this year.
Its implementation was, however, deferred following representations by traders who demanded some more time to clear their stocks.
Himachal had already banned smoking in public places and state capital Shimla had been declared a smoke-free city.
