How many cigeretts and tobacco can you bring back from Barcelona?

According to the Spanish customs regulations, visitors can bring the following tobacco and cigarette products into the country for personal use:

- Cigarettes: 200 cigarettes or 1 carton (10 packs of 20)

- Cigars: 50 cigars

- Smoking tobacco: 250 grams of loose tobacco

- Other tobacco products: 100 grams of other tobacco products, such as snuff, chewing tobacco, or pipe tobacco

It's important to note that these limits are for travelers over the age of 17, and it is prohibited to bring tobacco and cigarette products into Spain for commercial purposes. Additionally, these limits also apply to duty-free purchases made at the airport.

For more information on tobacco regulations in Spain, I recommend checking the official website of the Spanish customs (Agencia Tributaria) or contacting the Spanish embassy or consulate in your country.
