The ban on smoking in the Canary Islands will come into force on Friday, along with a requirement to wear masks in all public places.
The Canary Islands were the only area in Spain where face masks were not yet mandatory.
Officials in other regions, including Madrid and Andalusia, are also considering similar restrictions on smokers.
“Smoking will not be allowed in open places, in places where there are crowds, if there is not enough social distance,” Canary Islands President Angela Torres Torress told a news conference.
In Galicia, the ban on smoking in public places came into force last night.
In Galicia, smokers are prohibited from removing masks to smoke in a public place if it is not possible to keep a distance of at least two meters with other people.
Galicia and the Canary Islands are among the least affected areas of the new coronavirus in Spain, which has the highest number of infections in Western Europe.
The Spanish Epidemiological Society called for a ban on outdoor smoking in July because of the risk that infected smokers who do not have the symptoms of Covid-19 could spread small particles of saliva into the air and thus endanger the rest of society.
The World Health Organization (WHO) says smokers can increase the risk of transmitting the virus because it involves finger contact with the lips.
Many medical experts welcomed the smoking ban, while others questioned its effectiveness, saying there was no convincing evidence that tobacco smoke could transmit the virus.
