That was a habit that most people who practices it find it difficult to stop ,but in your case, you fought it and put an end to smoking , thus experiencing an enhanced health condition. Being mindful of what goes into our body system is important. The effect of cigarettes and excessive alcohol are so terrible and I hope humans can be intentional about what they consume. Water remains the safe liquid and I must commend that your friend for such discipline to stick with water only
