The Scottish Government could bring in a complete ban on advertising for e-cigarettes and vaping products.
First Minister Nicola Sturgeon said a consultation on the move would take place in the “coming months”.
She pledged if evidence supported further regulations on the sale of such products her government would “not hesitate” to act.
Ms Sturgeon spoke out after being asked about deaths in the US that have been attributed to vaping.
Three confirmed cases and two probable Massachusetts cases of vaping-associated pulmonary disease have already been reported to the US Centres for Disease Control and Prevention.
While an estimated 3.6 million people in the UK use e-cigarettes and vaping devices – up from 3.2 million in 2018 – Ms Sturgeon said their popularity in Scotland was still “relatively low”.
Speaking at First Minister’s Questions, she said: “The approach we have taken has been very cautious.
“That is perhaps one reason why e-cigarette use remains relatively low in Scotland… our approach has been a precautionary one.”
