Mae'r canllawiau hefyd yn cynnwys cyngor i ysgolion ehangu eu polisïau ar ysmygu ac ymddygiad i fynd i'r afael â'r cynnydd mewn defnyddio e-sigaréts. Anogir ysgolion i ddatblygu'r rhain gyda dysgwyr, staff a chymuned ehangach eu hysgol.
The guidance also includes advice for schools to expand their smoking and behaviour policies to address the rise in vaping. Schools are encouraged to develop this with learners, staff and their wider school community.
