If You’re Still Smoking Weed at 30, Scientists Have Bad News

There is no established “safe” quantity of cigarettes that one can smoke daily. Any level of cigarette consumption can elevate the risk of cancer development. However, the likelihood of developing cancer increases with the number of cigarettes smoked. A study conducted in 2021 involving 229,028 participants from Australia aimed to assess the probability of individuals developing cancer by the age of 80. The findings revealed that only 1% of individuals who had never smoked were diagnosed with lung cancer by the age of 80. Conversely, the risk of developing lung cancer rises to 14% for smokers. For those who smoke between one and five cigarettes daily, the risk is approximately 7.7%, while individuals who smoke more than 35 cigarettes each day face a 26.4% chance of developing lung cancer by age 80. It is important to note that smoking is not a prerequisite for developing cancers associated with tobacco; exposure to secondhand smoke also heightens the risk of lung cancer.
