And more importantly, how can you get rid of it
A couple of years ago, you would have no other choice than to make homemade juice according to your own specs [as no commercial e-liquids went above this threshold of regular nicotine in their juices]
Food: Certain foods can accumulate heavy metals from soil, water, and air: Rice: Can contain arsenic due to soil contamination or water used in its cultivation
These commercial tobacco products are, however, addictive
And thats before you start looking at property damage (three housefires a day in London alone are directly attributable to lit tobacco), pollution, etc caused by lit tobacco that either arent applicable to reduced risk products (Im quite sure Snus hasnt started any house fires, ever) or are massively reduced (The fact that battery fires related to e-cigs are newsworthy is testament to how rare they are notice how you dont see news stories about cigarette fires) by these products
