Show him a picture of a damaged liver, lungs, eyes caused ny smoking.

what does he smoke? is it cigarette or weed ?

if its weed , then leave the guy . you said he is one of the best students in your class, that's because the weed opens up the locked corners of his medulla

weed is not a bad thing if moderate.

stop condemning the holy leaf

just discuss the long term bad effect with him. that won't stop him though, if he's been smoking for 3 months plus. Cigarette addiction is quite strong especially when a supposed intelligent person smokes it, cause he's already aware of the cons. If he smokes it for the tiny bit of euphoria nicotine gives, introduce him to cannabinoid edibles, it will completely blow his mind and he make him uneasy; he may completely lose interest in euphoria inducing drugs( this is method is not practical tho, but it worked for my niece). If he smokes to relief stress or for calmness, then I don't know what to say.

There is this guy in my department, he is among the best students in my class and a friend too but recently I discovered that he smokes cigarette(like I caught in the act),I was so surprised because I think he is still young for that(about 18 years of age)....what surprised me most is that as he is an intelligent person,I think he should know the risk of smoking....what advice can.I give him to stop it [s] so as him not to constitute nuisance in the future and even in this country(cos youth are the leaders of tomorrow as they say)

smokers are no nuisance to the society.
