My younger sister (18) started smoking pot about little over a year ago. Not soon after it become an everyday thing. She does it in her room & is allowed to. Parents dont care.

Just like me when i started, i was 13 at the time though, shes been dressing differently, cut her hair, not taking as good care of herself as she used to. For me maybe because it was at such a young age smoking pot to me was like an adult smoking crack. I started stealing for drug money, started using other drugs, stopped taking care of myself, became depressed & I believe it has had long term effects on my psyche. I dont want me sister to have to go down the same path.

I think pot is a dangerous drug to give to a teenager. Its a gateway drug & destroys your personality & mind especially if you’re doing it everyday. (some people are more susceptible to side effects other can smoke it & be mostly okay)

Is there any hope or any way i could persuade her to stop without sounding condescending?
