Nicotine patches, a good alternative?

Hello folks,

I am currently looking for the least harmful way to consume nicotine.

All this smoking, vaping, and snus is far too harmful for me. Vaping and snus don't seem to improve my shortness of breath much either.

Wouldn't nicotine patches be a good alternative?

They may not be cheaper but in my opinion they are not as harmful.

My specific questions:

Are nicotine patches more harmful or "healthier" than smoking, vaping, or snus?

Can I use nicotine patches to consume nicotine?

At what age can I buy nicotine patches?

Yes, I'm a minor, but I'm still worried about my health. I know quitting would be the best course of action, and I also know that what I'm doing isn't entirely legal right now. However, I'd like to see an objective approach to this issue.

Have a nice day dear reader
