Where are teens exposed to ads about tobacco products

Teenagers are usually exposed to those kind of ads one social media sometimes or posters on some convenience stores. Most social media ads are against tobacco products now, but there are some teenagers who choose to ignore the warning and do the opposite. On convenience stores the posters they have on the wall usually promote the tobacco products so people buy them so the store it self is making money.

I'd say mainly through media (t.v, instagram, youtube, facebook etc) but also normal advertisement in real life. i've seen many posters of tobacco companies advertising their product.

The attention line is placed above the recipient line, that is, above the name of the firm to which the mail-piece  is directed.

You didnt put any descriptions, so i can't really tell ya which one is the best since you don't even have any..sorry.
