Are care packages offensive or appreciated?

I am a college student with limited finances, but my college has a big homeless population. A friend and I want to make care packages with gift cards, water, granola/protein bars, handwritten notes, sweet snacks, cough drops, socks, pens, paper. We would get cigarettes, but we are not 21 yet. We genuinely want to know if care packages help. As students, we can't really get to the closest shelter, but we see many homeless on the streets. We want to ask if they want a package and hand one to them if they say yes.
