How to get my dad to stop smoking pot?

I recently found a stash of a tiny amount of weed in a medicine bottle in our bathroom. I have found one other stash before, and I asked him about it, and he flat out denied that he does. He currently has no job, and asks my grandmother often for money. How should I address to him that I know he smokes, and that I want him to stop?

I don't think you should address it. It's his business, and many people smoke pot. If you'd found a suitcase of it, I could see a cause for concern... but let him be. Maybe it's a good stress relief for him if he doesn't have a job. Try not to be so judgemental.

Again...I agree with pink pearl. Let him be...he could be an alcoholic, which is legal, but a lot worse

if it's not affecting your life or his, what's wrong with smoking from time to time. Let his business be his, remember he is an adult, and he may be offended by his child trying to be the parent. Don't make the situation more than it is, sometimes you have to pick your fights.

His an adult im sure he has his own issues, Its probably stress relief for him stay out of it.

In a way I do agree a bit with what everyones saying but I've been in that situation myself, and if I were you I would leave it for now but if he dose anything that concerns you or you end up having a heart to heart just bring it up eventually he will come clean...when I confronted my dad he did the exact same thing total denial he even said he was willing to go down to the hospital and take a drug test, when my sister and I both knew it would be positive because we saw him smoking a joint on the deck lol but if its a really big concern and your really worried just tell him that you know he smokes pot and your concerned I mean whats the worst that could happen

Good Luck

give him more

Who cares.
