Replying to Stupidest thing EVER

ok so 2 weeks ago, my mom booked me with weed. now, instead of grounding me or something, she is making me write a 2 page essay about the negative effects of weed use. she says this is because im "too young" to smoke weed. im 15 years old in grade 9. also, she grew up in the 60s and 70s, so whatever she tells me about "never trying it as young as me" is complete bullshit. sorry it seems like im just bitching in NSG, but what do you guys think about my situation?
