“At that time there was a bhikṣu suffering wind. The doctor instructed him to use 'smoking'. The Buddha said using 'smoking' was permissible.”

They knew how to smoke and clearly did. It was part of Ayurveda. Again, it wasn't tobacco, but probably opium or cannabis. Also, this was for medical reasons, not to get high.
No, niether cannabis or opium is intended here. Smoking a specific blend of medicinal herbs that are good for the lungs is mentioned as part of dinācarya (regular conduct) in the Caraka Saṃhita.
