Tobacco is a legal but addictive drug in Spain. Smoking one pack per day can cost over €1,150 per year. It is difficult for smokers to quit due to psychological addiction, though nicotine replacements can help. Many teenagers smoke because of peer pressure from friends, so it is important to say "no" if offered a cigarette to avoid manipulation or harder drugs in the future. Smoking causes both short-term effects like increased blood pressure and long-term health issues including lung disease, heart disease, and various cancers.
