You sound a bit preachy and judgemental. Nicotine is very addictive, do you think most smokers wouldn't like to have a cigarette then leave it? I took up smoking because of stress and then oops! I became addicted, just like that. Tobacco smoke is harmful, vaping 'fumes' (???) are not. I use cbd now, i have arthritis and fibromyalgia, bypassed the whole nicotine vape thing, so....going to preach about that now?
